Given that we are in an exciting period of space exploration and discovery, our Internet needs may soon extend beyond the earth. With this in mind, let ’s talk about the moon ’s Internet access.
Super long distance service provider. The real value of the Internet is that it makes it easy to transfer data between the host and the computer, but this is not the only way to share information over long distances. For data transmission related to space laser pointer exploration, radio frequency data transmission (ie radio frequency data transmission) technology is usually used because it is reliable and simple, although it is very slow.
However, the demand for fast information transmission becomes more and more important, and as more satellites and long-distance space travel in the future, we will need faster transmission speeds. If radio frequency data transmission technology is used, high-resolution images and videos require a lot of time to complete the transmission, which simply does not work in a society that desires speed and instant satisfaction.
In view of this, researchers from the Massachusetts Institute of Technology (MIT) and NASA have joined forces to solve this problem. After years of unremitting efforts, scientists have developed a telescope system based on red laser pointer, which can provide fast Internet access for future astronauts on the moon and deep space exploration.
The principle of the laser telescope system is as follows: Four ground telescopes transmit encoded infrared pulses into space, which are then captured by telescopes mounted on moons orbiting the moon. The earth ’s atmosphere will slightly interfere with the pulse signal, which is why four synchronized pulse signals need to be transmitted, which keeps the connection stable and complete. Subsequently, the telescope on the satellite focused the infrared beam on the optical fiber, and the photodetector in the optical fiber interpreted the flicker of the light as an electrical pulse, and then converted it into data.
