Understanding Cat Sounds (Includes Video Examples)

Cat's Meowing and Other Cat Sounds Cat sounds are the way felines communicate with humans, with other cats, and with other animals. Although domesticated cats can make more than a dozen different sounds, adult cats in the wild are mostly limited to non-vowel sounds. Kittens in the wild use meows with vowel sounds, but adult felines do not . Domesticated cats of all ages have a fairly large repertoire, however, as a form of learned behavior. These kitties have learned that insistent meowing can quickly get their human owner's attention. All cats make sounds, but some are more vocal than others. For example, kittens are usually more vocal than adult cats, and cats with close associations with humans are usually more communicative than feral cats. Some breeds are also more gifted with their cat sounds, including Siamese, Burmese, and Korat. These breeds generally vocalize and use cat meowing more often than other felines, but remember that each cat is a unique individual. You might have a Siamese that's very quiet, or you might find a Maine Coon that's loud and almost constantly meowing. Below are the major cat sounds made by felines, with a short description of each. Use these as a general guideline, but learn to understand your own individual pet - unless you can get it to read and emulate the following sounds and situations! Cat meowing The most common cat sounds, especially with domesticated pets, is the cat meow. If you own a cat or two, you know that not all meows are equal. Different meows mean different things, and meowing is your feline's most important way of communicating with you. By the way, have you ever noticed that cats do not meow with each other? Nope - they reserve these cat sounds for their humans. If you've had much experience at all with cats and cat sounds, you are probably pretty good at figuring out if your cat is angry, happy, or demanding, just by paying attention to its meowing. You cat might have a chirp-like sound it uses as a greeting, a longer, whining "meow" when it wants something like food or water, and an exaggerated "yowl" when it's seeking a mate. Generally speaking, low-pitched, long cat sounds are used when a cat is unhappy, while shorter, high-pitched cat sounds mean that your furry friend is happy. Why is this so? In the wild, deep cat sounds might make the cat seem larger and more threatening to potential predators. High-pitched cat sounds make the cat seem more vulnerable and more endearing to us humans. For example, a short, high-pitched chirp is often how your cat says hello. If your cat wants something, the meows are usually louder in order to get your attention. Murmuring Murmuring is similar to a closed-mouth meow and is often heard in conjunction with purring. Murmuring is a sign that the cat is content and at ease. Chattering Among all cat sounds, chattering is perhaps the most unusual, but it's somewhat difficult to describe. Think of it as a cross between a meow and the bleat of a sheep or goat. It's kind of like a stuttering meow. Chattering is usually a sign of excitement, frustration, or a combination of the two. You might hear these cat sounds when your pet felines see something that they want but can not get to it. Growling Growling cat sounds are deeper and more insistent that murmuring and are meant as a warning. Growling might be used as a response to humans, other cats, other animals, or to situations. If your cat growls at you, leave it alone. If your cat is growling at something else, discover the source of the cat's displeasure. Cats growl because of fear, anger, and territoriality. Squealing These high-pitched cat sounds are unmistakable and are a cat's version of screaming. Squealing or shrieking is usually a reaction to sudden pain, surprise, or aggression. Squealing is more of an unintentional reaction than it is a form of communication. Hissing Cats do not use this sound much, but when they do, you need to pay attention. Hissing is most often a response used when the cat feels frightened or threatened. The sound is usually used with other felines and other animals, but it might also be used with humans. When a cat hisses at you, give it some space. Move away slowly. Once the cat feels that the threat or danger has been removed, it will calm down. Purring Animal experts are still a little perplexed by purring cat sounds. For long years, most people assumed that cats purred only when they were happy and content. While this is true in many cases, there are exceptions. Injured cats and very nervous or fearful cats have also been observed purring. Now animal behaviorists believe that cats might purr as a form of self-comforting when they are in physical or emotional distress. Interpreting cat sounds on your own By paying close attention to your cat's meowing and other vocalizations, you will soon learn to interpret the various sounds on your own. In addition to the specific sounds, use other physical clues to decipher your feline's efforts at communicating, including a twitching tail, laid-back ears, and other body language that helps you tell whether or not your cat is happy, in pain, fearful, or angry. When you put these together with the various cat sounds, you will have "felinese" down in no time! Cat chattering: Whining, pleading cat meowing:

Application of Operational Amplifier As Differential Clamp Diode in Comparator
Application of Operational Amplifier As Differential Clamp Diode in Comparator
The influence of internal differential input clamp diode on operational amplifier when operational amplifier is used as comparator. I ask a question - will these clamps affect the operational amplifier circuit? If the voltage between the two inputs of the operational amplifier should be about zero, then these diodes will never be forward biased in the standard operational amplifier circuit... Or will they be forward biased? A little reminder, we are discussing some differential clamp diodes that may appear in some operational amplifiers, see Figure 1.Generally, the influence of operational amplifier circuit can be seen in the basic non inverting amplifier configuration structure (including a simple g = 1 buffer amplifier). Let's look at a forward input step. The output cannot immediately follow the change of surge input voltage. If the input step is greater than 0.7V, D1 is conductive, affecting the non inverting input. When the operational amplifier is turning to its new output voltage, the current at the input of the operational amplifier will suddenly increase to a higher peak value, as shown in Figure 2. Finally, when the output "catches up" with the input, everything gets better again.Many applications themselves process slow or band limited signals, which is much lower than the conversion rate of operational amplifiers, so this will certainly not happen. In other applications, even if the input voltage changes rapidly, the input current transient will not adversely affect the operation of the circuit. However, in some special cases, the input current pulse will cause many problems. One notable case is the multiplex data acquisition system. The following figure shows a simplified case of this system with only two input channels.In this example, the multiplexer switches between channel 1 and channel 2, so it is required that the output of U1 can be quickly converted from - 5V to 5V. The forward bias of D1 and the resulting input current transient pass through the multiplexer switch, thereby releasing the voltage of C2. The R / C input filter is usually used to maintain a stable voltage during channel switching, but the current pulse partially discharges C2. Now, C2 needs more time to recharge to the correct input voltage, which reduces the multiplexing rate, that is, the accuracy. The solution is to select an operational amplifier without differential clamping for U1. FET input amplifiers such as opa140 have low input bias current (to reduce the burden of MUX series resistance) and no differential input clamping, which is very suitable for multiplexing input. Opa827 performs well in most applications - FET input, very low noise, high speed, stable and fast. However, it has some differential input clamping, so opa827 may not be the best choice for operational amplifier multiplexers. Previous posts focused on differential clamping and introduced the general principles of using various types of operational amplifiers. Refer to "operational amplifier as comparator" for details. I don't want readers to have the impression that differential input clamp operational amplifiers are risky and should be avoided, but this is not the case. In a few cases, they will affect your circuit. But if you know this, you won't make blind choices. Do you find that differential input clamping affects your circuit in other ways?
What Specification Should You Be Looking for with a Portable PA System?
What Specification Should You Be Looking for with a Portable PA System?
Suitable for both indoor and outdoor use, with a complete system you should aim to get one with a 12V rechargeable battery which charges when the system is simply plugged into the mains, it houses both a CD player with USB port for MP3 playback and a UHF Radio Microphone receiver which should come with a handheld radio microphone as standard.Looking to get one with an onboard voice priority circuit operated by a single switch will enable the music to be mixed discreetly into the background whilst announcements are being made over the microphone making it a very versatile for professionals and beginners alike.The whole unit is incredibly portable with wheels and a pullout handle for manoeuvring and it has a pole mount for sitting on top of a speaker stand. The system is just one single speaker, though you can buy additional active or passive units to add and supplement the sound from a large range of PA systems. We recommend buying the system with a single lightweight speaker stand and a waterproof cover to ensure it remains portable and even use it in wet conditions.We would recommend getting a Portable PA System which has the following features incorporated: 200W Music Power, 12V Rechargeable Battery that has a 10 Hours Charge Time. Ideally you should get around 6 Hours Music Play whilst running on battery with around 10 Hours Speech Time whilst on the battery. With regards to input and output you should be looking for microphone inputs and 1 line input, with additionally an active output with line out and speaker out.If you intend on using this for multipurpose I would recommend getting a remote control which can be used with the CD player which on board. In addition to a CD player you should be able to have the option of a cassette deck and extension speakers. The microphone that you should get with the above spec will most likely to be on the 863 - 865MHz Frequencu Range, UHF.

I Have Bryant Furnace and the Led Light Does Not Come on, Would That Indicate a Bad Board?
Yes it could indicate a bad control board, but it could also indicate a faulty door switch not allowing power to the board to start with, or could be a problem with power supply to the furnace1. I have anight light in my bath room. It's an LED light if that matters. It is angeled toward the mirror.?is this really a ?2.

I bought LED Light to go under my motorcycle, i know how to run it to my battery, but it just came with wires?You just need to add an on/off switch between pos. wire and the battery. Like Jeremiah J says, if you are not tech savy, find some one familiar with automotive electrical wiring6. 10000k led light strip and anemones?That light by itself is probably not enough for an anemone. Those are probably 1w leds which do not have the power to penetrate very deep through the water. It would help but if it is enough or not will depend on what other lighting you have with it.7. back led light on bumper. rite side not working but the light is lit and showing under the car?The internal lamp holder, mirror and support have popped out and hang somewhere. Have someone fix that, should be fairly easy. It may bring about a short-circuit, meaning a fuse would blow and that's about it. The only consequence would be another light (on the same side or diagonally opposite) will also go off. A simple/cheap fix. If the electrical system is in good shape, no fire risk. Depending on where you use the car - ticket risk if lights are off due to a short.8. How do you achieve this stairway 'chaser' effect with an LED light strip?What makes the light "run up the stairs" is the use of individually addressable LEDS. That means each LED on the strip has a microprocessor that can be called up and say "hey, you, turn on at this RGB value: 0x999999". That adds a bunch of complexity. Not least, the microprocessors that monitor the PIRs and sequence the LEDs in the direction being traveled. However, there's no end to the cool: the processor could roll pulsing light up or down the stairs... or it could even do rolling rainbows of color, like Boeing Dreamliner or something, because virtually all these "individually addressible LEDs" are RGB color type. It's there; the poster just has not unlocked it because the limiting factor is software (you have to write it). It also forces the installation to use 5 volts DC instead of 12/24 volts DC. This means the power supply must be heavier, and the wires must be much heavier. Parts list is: You can do the kaboodle on 12V or 24V, and so the wires get a lot smaller. You can drop the microprocessor altogether, and simply use 12/24 volt PIRs wired in parallel. (i.e. whichever PIR sees a customer turns the lights on, and the lights come on when either PIR asks for it, and the PIR auto-times out after a time.) You can also use simple, cheap 3528 monochrome LEDs in your choice of color temperature. Most 12 volt PIRS will happily run on 12V or 24V. So will dimmers. So you just get 12V or 24V LEDs to suit. Your parts list is:

Application of RFID Baggage Sorting Technology in Air Parcel Identification
Application of RFID Baggage Sorting Technology in Air Parcel Identification
Corresponding management of aircraft passengers and checked packagesFor the aviation industry, millions of passengers and checked baggage are handled every day and transported to their destination safely and on time. RFID tag is applied to the tracking and management of air parcels to ensure that airlines can track, manage and confirm passengers and checked baggage, so that passengers and checked baggage can arrive at their destination safely and on time. RFID electronic tag system can be simply integrated into existing baggage tags, check-in printers and baggage classification equipment. The system can automatically scan bags regardless of the placement direction and whether they are stacked or not.Through the baggage handling system, airlines can effectively solve most of the problems of misloading and misdelivery of checked baggage, and greatly reduce the amount of compensation for baggage loss. Airlines can take advantage of RFID system to plan ahead and prepare for customer baggage problems in advance. In addition, the RFID system can also inform the customers who pick up their luggage in the form of signal through the customer's mobile phone, so as to improve customer satisfaction.The field test shows that RFID system is more secure and reliable than the existing bar code system. The reasons why RFID smart tags are more suitable for the aviation industry include:1. It can be easily connected to the existing control system (DCS) and baggage management system (BRS), and can be combined with the existing bar code system.2. The data storage capacity is increased without increasing the size of the existing label.3. Some key information in the package original information (BSM) can be carried, so that the package can be operated without going through the central database.4. It can be easily integrated into the existing package label printer without adding additional equipment.5. The use of electronic labels can save some additional equipment costs during transportation.RFID baggage sorting technology processPreviously, the baggage sorting technology of the airport was realized through bar code identification technology: 1. On the check-in counter, the baggage was labeled with bar code label. 2. After security check, the baggage is transported to the entrance of the baggage handling system. This is the main basic process, but the problem comes. After the baggage enters the sorting system, the barcode label is often blocked or the angle with the code reader is too large, resulting in the failure to scan the barcode, resulting in the retention of the baggage. As a result, more and more airports begin to use RFID radio frequency identification technology better than bar code identification technology:1. First, during check-in, the baggage will be tied with a white card RFID tag like a work card or an inlay RFID tag instead of a bar code tag. 2. A UHF RFID reader and four antennas will be used in the system to form an omni-directional 360 degree coverage. 3. In this way, the reading and writing device can sense the electronic tag and obtain the tag information through the wireless RF signal.British Airways has achieved good results after fully adopting baggage tagsBritish airlines used RFID smart tags to test 75000 packages on the routes from Hislo airport to Manchester airport and Munich Airport in Germany, and achieved good results. The experiment fully proves the efficiency of package identification and tracking management in package classification system by using RFID smart tag system. In order to promote this technology, British Airways has disclosed all the test data to other airlines and international standards organizations.In terms of baggage sorting technology, RFID technology has the following advantages:1. The scanning is fast, and the barcode scanning is one-to-one correspondence, while the UHF RFID reader can identify and read multiple RFID electronic tags at the same time.2. With small volume and diversified forms, the reading of RFID technology is not limited by size and shape, and does not need to match the fixed size and printing quality of paper for reading accuracy.3. It has strong anti pollution ability and durability. The traditional barcode carrier is paper, which is easy to be polluted, while the RFID tag stores the data in the chip, so it can be free from contamination.4. Reusability. Most bar codes cannot be changed after printing. RFID tags can repeatedly add, modify and delete the data stored in RFID volume labels to facilitate the update of information.5. Penetrating and barrier free reading. When covered, RFID can penetrate non-metallic or non transparent materials such as paper, wood and plastic, and can conduct penetrating communication. The bar code scanner must be close and there is no object blocking before it can read the bar code.6. Security, because RFID carries electronic information, its data content can be protected by password, so that its content is not easy to be forged and altered.fqj

Why Doesn't Panera (or for the Educated, St Louis Bread Co.) Stock More of Their Popular Items Such
Sales fluctuate wildly from hour to hour, day to day, week to week, etc. What's popular one day might be cannon fodder the next. Managers likely base their orders on what sells the most in any given season and go from there. Why does not Panera (or for the educated, St Louis Bread Co.) stock more of their popular items such as muffins, souffles, etc, because they run out every morning?1. Amazon.ca Best Sellers: The most popular items in Outdoor Fire PitsOutland Firebowl Natural Gas Conversion Kits for Specified Models of Portable Propane Fire Pits, Complete 3 Piece Set - 12 Foot Hose, Quick Connect/Disconnect Coupling and Valve - CSA Certified for Quick & Easy Conversion (780 NGCK for Selected Manual Ignition Firebowls)2. Buy popular items off ebay then sell them for a higher price?No for a few reasons: 1. If it's popular, you can be sure that there will be hordes of other people who either want it for themselves or have the same or a similar idea as you do. 2. If you do manage to win the item, you will have to re-list it with eBay and Paypal (or whichever service you plan to use) fees in mind on top of whatever profit you are aiming for. The price will likely exceed the perceived value of whatever it is that you are flipping. To make it worthwhile, you are better off finding someone who will take it off your hands in person. 3. If you are planning to auction the item, there's no guarantee that you will get the price you are asking for. If you decide to put a reserve on it, you may end up losing potential bidders. If you list buy-it-now, you will have to wait for someone who's willing to pay your asking price. Many goods depreciate in value rather quickly and you may have to deal with undercutting competitors. 4. Depending on the popularity and availability of the item, you may also need to account for delivery times. If it's something currently in high demand, you have to decide whether or not the same item will be worth your asking price a week or two later. Unless you are real lucky and get a good closing price on something with high demand, flipping on eBay wo not be worth your time or effort.3. What do you think are the most popular items at a yard sale?I was going to say books too. Toys and sporting equipment, also musical instruments, tools. One thing if it is in an original package it can go for more. Just be careful I watch Antiques Road Show, people buy stuff for $5 or $10 bucks and it can be appraised for hundreds or thousands.4. What is a nice gift for Canada's "Inuit" people?I agree with my fellow NDN's on this. The non-natives answering this know dick all about what they are saying. We are big gift givers. It is a good way to honor people. When we have giveaways, or partake in them, popular items are, hats, t-shirts, bandanas, berries, cornbread, plants, fabric (nice cottons or satin) and craft supplies but I can see why you personanly may want to avoid glass beads...lol.

Solution of Vehicle Communication Video and Audio System
Solution of Vehicle Communication Video and Audio System
Mobile video applicationRecently, mobile video has developed into a feasible and even necessary accessory of car entertainment system. The selling point of several new recreational vehicles and small business vehicles is to take mobile video as an option. More and more people have considered installing video entertainment system on their vehicles.Fig. 1 car audio-visual system using LCD displayThere are many reasons for the rise of mobile video:Entertainment application - car is an entertainment environment where you can play video games, watch movies, cartoons, regional TV and even satellite TV. Because of the progress of mobile video technology, all these can now be realized in cars, trucks, business cars and recreational vehicles.Safety - when video is connected to the navigation system, it can send image and sound commands, which can increase travel efficiency and accuracy.From the development trend, car entertainment has evolved from the traditional pure audio mode, such as MP3, to a display integrated system integrating user manual and navigation functions. The in car entertainment system now also provides all-round entertainment functions, and the size of the display ranges from 3-inch medium size to high-end 7-inch mode. The display content usually includes analog information (such as DVD player output or digital radio and television) and digital information (such as multimedia interface or interesting wallpaper). The image processing chip ssd1921 of Jingmen Technology Co., Ltd. has these characteristics that can meet this new market demand.Ssd1921 image processor overviewJingmen technology ssd1921 is an image processing chip with image capture and processing functions. The image content can be processed by ssd1921 and displayed on various types of LCD panels, such as STN, CSTN, low-cost delta panel, and high-definition strip TFT.Figure 2 shows the application solution for car audio and video. Video decoding first converts CVBS (composite video signal) or S-Video signal into YCrCb (bt656 / bt601 digital format) and transmits it to the video input port of image processing chip ssd1921. If the video signal source meets the bt656 / bt601 standard, the design can be simplified, that is, there is no need to connect the video decoder. In most cases, the video input may not always correspond to the display panel at the ratio of 1:1, and ssd1921 has the function of "size adjustment", that is, the image data can be cropped and scaled before being written to the embedded SRAM. Therefore, NTSC / PAL video sources with various resolutions can be adjusted through this built-in scaling engine to be suitable for display on LCD panels with different resolutions.Figure 2 ssd1921 solution for automotive audio and video applicationsWhen the frame buffer in the 256Kb built-in memory is configured, the DVD image will be displayed on the LCD screen. This image processor can support up to 640x480 triangle arrangement (200KB) and 480xrgbx272 stripe arrangement (255kb). Color depth can be supported to 1, 2, 4, 5, 16 and 32 bits.The built-in 2D image processing engine provides flexible screen display effects, including screen display, translucency, multilingual font acceleration, dynamic JPEG animation, image scaling, virtual display, portrait display mode, coverage function, hardware cursor function, line drawing, raster operation bit block transmission, color filling and expansion. The internal JPEG engine can provide a highly customized user interface. For example, the user can capture his / her favorite and interested DVD images as a screensaver, or take personal photos as wallpaper. To achieve this function, users need to store JPEG images on SD / MMC card in advance, and ssd1921 can obtain the pre stored images from SD / MMC, decode and display them on LCD.Single chip integration solution for simplified application systemJingmen technology ssd1921 image processing chip integrates these main characteristics for vehicle audio-visual applications: video input interface, JPEG codec, 2D image engine, SD card interface, MCU interface and display interface. The single chip solution plays an important role in reducing cost and simplifying the system in this application system.Figure 3 structural block diagram of ssd1921The video input port on the chip can accept the general 8-bit digital video signal format YUV422, ccir601 or ccir656. Because CMOS and CCD sensors also use these two interface standards, designers can directly connect the image source of the sensor to the video input port of ssd1921. In addition, the video image can also be transmitted to the video input port of the image processor at a maximum frame rate of 15 frames / second. In today's car audio-visual products, in addition to the function of DVD recording and playback, static picture display (such as operation menu display and photo display) is also a very important feature. The ssd1921 can support CMOS image capture with a maximum resolution of 1280x1024 (equivalent to 1.3m pixels). If the video source is too large to display, the chip's built-in extraction and clipping engine can scale or trim the input video with a fixed size (1, 2, 4, 8, 16) to match the display output. Images up to QVGA (320x240) 16bpp color depth can also be previewed by cutting and extraction engine. In addition, the chip can also realize color conversion, that is, color change from fixed YUV format to RGB format, including YUV422 to rgb565 and YUV422 to rgb888 format (32bit color depth with 8bit color mixing). The user can adjust the Y, u and V components according to the requirements of brightness and contrast.JPEG encoding and decoding is pure hardware encoding and decoding. JPEG encoding and decoding can be completely separated from the operation of MCU (microcontroller unit). JPEG encoder compresses the video source into JPEG format and stores it in embedded memory, and supports JPEG encoding of various sizes up to 1280x1024. However, when the JPEG decoder receives a JPEG image from MCU or MMC / SD card and decodes the display, the size of the decoded image is limited by the display size or the size of the embedded memory. Extraction and clipping are two algorithms to reduce image size and memory requirements. Bus width and power consumption can also be saved accordingly. Cut and decompress the selected area of the whole picture, and non integer extraction can be realized by StretchBlt function in 2D image processing engine. Because the maximum resolution of the video input port is 1280x1024 and the embedded memory on the chip is only 256Kb, it is impossible to start JPEG compression after complete frame capture. The only way is to start compression while the image is captured.A 2D image processing engine is built in the image processor. Its design is based on GDI (graphics device interface) of Microsoft Windows. It supports the following seven main functions:Screen panning and scrolling;Image rotation, including: 0, 90180270 degree rotation;Cursor with three colors and transparency, the cursor can flash;Line drawing;Rectangle drawing;Ellipse drawing;Bit block transfer (BitBlt) - the purpose of bit block transfer engine is to transfer pixel data between CPU and video memory without the control of MCU. It can also be used to move pixel data from one specified position to another in video memory, so users can easily move a pixel pattern in video memory. The processing of larger images can be realized by repeating the transfer of hatch bit blocks several times. In addition, the color expansion function of the bit block transfer engine has the advantage of bit storage, so it can save memory. Allows users to apply Boolean logic functions to source and destination data, reflecting a high degree of flexibility in data management.Similar to other controller chips of Jingmen technology, ssd1921 also integrates MCU interface and display interface. The wide range compatibility of these interfaces reduces the complexity of design. The display interface supports most panel types, including monochrome and color STN (4 / 8 / 12 / 16bit interface), TFT (9 / 12 / 18bit interface), hr-tft (18bit interface) and 8bit serial TFT interface. For STN and CSTN panels, spatial and dynamic jitter can increase color depth. In addition, ssd1921 provides direct interfaces to various MCU, including low-end 8bit and high-end 32bit MCU. These MCUs include Freescale 68K, Dragonball series, Renesas SH3 and SH4 series, and Intel StrongArm / Xscale series.epilogueVehicle audio-visual system has become popular and has a very large potential market. Car entertainment will eventually become an important part of every car in the future. The monolithic integrated image processor such as ssd1921 is very suitable for various vehicle audio-visual applications. Its remarkable characteristics and simple system design help manufacturers speed up the introduction of products.
Space Laser Communication May Open a New Era of Data Transmission for Future Space Military Applicat
Space Laser Communication May Open a New Era of Data Transmission for Future Space Military Applicat
The development of the information age requires the establishment of a communication network system with fast transmission rate, large amount of information and wide coverage space. Space laser communication mainly uses the laser as the carrier to load the information onto the laser and transmit it in free space such as outer space. At the receiving end, information transmission and communication can be realized through a series of photoelectric transformations. In today's increasingly crowded space satellites, they have received extensive attention and research from various space military powers.Space laser communication system has smaller volume, lighter weight and lower power consumption, which is the power source to help it go to space. Previously, the United States has accumulated a solid technical foundation through a series of research projects such as "laser communication Demonstration System", "international orbital space station optical communication", "synchronous orbit Lightweight Technology Experiment", "Mars laser communication Demonstration System" and "transformation satellite communication system". At the same time, Europe and Japan have successively carried out inter satellite laser communication experiments. Russia has also used laser communication to transmit electronic data back to the ground receiving station, and transmitted 2.8gb of space data in one breath.Compared with the traditional radio communication, space laser communication technology uses light wave as the information carrier and has a larger available frequency band. At the same time, laser communication greatly reduces the possibility of information interception in the communication process, and has better confidentiality and security. It also effectively avoids the dilemma of lack of global radio spectrum resources, or will open a new era of data transmission for space military applications in the future.At the same time, space laser communication will also have great prospects in the civil field. Several commercial companies in the United States have invested heavily in the research and construction of space laser communication network, which will further promote the practical process of space laser communication.In the future, space laser communication is expected to become the key technology of data transmission between satellites and earth, and complement the ground optical fiber network, so as to establish a three-dimensional cross laser communication network including satellites and inside and outside the atmosphere, completely subvert the existing global communication system, and become a large bandwidth and high-speed communication network to meet the information transmission needs of the Internet of things era.
