NASA succeeded in data communication with the universe using laser at 622 Mbps

NASA (National Aeronautics and Space Administration) succeeded in experiments on laser communication which will be the next generation space communication technology. It records speeds of up to 622 Mbps and is expected to be applied to future high-speed, large-capacity data communications.

According to NASA 's announcement entitled "NASA' s laser communication system establishes record of interactive data communication speed with the moon," NASA announced that it is a lunar probe that orbits around the moon, which is about 385,000 kilometers away from the earthLADEEAnd the ground equipment of New Mexico State in the United States,622 MbpsWe succeeded in receiving data at the speed of establishing a new record. In addition, for reliable error-free communication, a speed of 20 Mbps was recorded. Up to now, the lunar orbiting satelliteLunar · Reconnaissance · OrbiterUsedExperiment, 300 bps recorded when communicating the image data of the masterpiece "Mona Lisa" was the best, but this time it was a markedly higher record than that.

Of this timeLLCD(Lunar Laser Communication Demonstration) program is an experiment program to replace conventional high frequency radio (RF) communication with laser beam, the communication speed faced by radio wave method NASA has been using for the first time into space We are gathering expectations as pushing up the limit of.

The movie of the LLCD program using this LADEE is released on the official NASA channel of YouTube.

On December 24, 1968, Apollo 8 was famousOut of the earthI took a few days before people on the ground saw that picture.


However, data communication using artificial satellites is now in practical use, and data can be shared in a short time.


When a radio signal (beacon) of connection request is issued from the ground to LADEE ......


LADEE which sensed it returns to the ground and returns radio waves.


Both sides are connected.


In this state, data communication by laser is started.


Mr. Badri Younas, Deputy Secretary of NASA's Space Communications and Navigation ("SCLN") said about this success: "LLCD is the first step to building the next generation of space communications environment.In the near future this I think that communication using technology will be put to practical use. " NASA is using this high-speed, large-capacity data communication technology and is planning to deal with image data of higher resolution than the past and 3D video data shot in deep space. This LLCD program is followed byLCRD(Laser Communications Relay Demonstration) program, and we are planning to demonstrate experiments in harsh outer space for several years. The system is scheduled to commence operation in 2017.

LADEE was a lunar probe launched on September 6 this year and succeeded in orbit launching the moon on October 6. It is aimed at observing the composition of moon atmosphere and dust and acquiring data for future lunar exploration.


This LADEE is also known as a "flying frog" together with a frog at the time of launch.
