Boeing has provided space communication services to NASA for more than 40 years, and has been NASAs sole provider of tracking and data relay satellites since 1995.
Using communication relay satellites such as EDRS-A, the SpaceDataHighway will be able to transfer high-volume information from Earth observation satellites, UAVs and surveillance aircraft, or even from a space station such as the ISS.
Using communication relay satellites such as EDRS-A, the SpaceDataHighway will be able to transfer high volume information (images, video, data collected by sensors) from Earth observation satellites, UAVs and surveillance aircraft, or even from a space station such as the ISS.
The relay satellites are designed to lock on to low-orbiting earth observation satellites via laser and collect their data as they travel thousands of kilometres below, scanning land and oceans.
To overcome this obstacle, China will use a relay satellite named Queqiao that was launched on May 20, 2018.
Now NASA is developing an operational capability with their Laser Communication Relay Demonstration (LCRD), a geosynchronous (GEO) relay satellite system designed to support terrestrial, airborne and low Earth orbit (LEO) users.

A relay satellite, named Queqiao (Magpie Bridge), for Chang'e-4 has entered a Halo orbit around the second Lagrangian (L2) point of the Earth-Moon system, about 65,000 km from the Moon in June.
For example, China is planning to launch a relay satellite in the first half of this year and a lunar probe next year, which is expected to make the first ever soft landing on the far side of the moon.
That 425kg relay satellite will also guide the second element of the mission, a lander and rover, down to a soft landing on the far side of the Moon,where nobody has gone before.
This technology is now being used commercially in space by laser communication terminals onboard Copernicus the European Union's Earth Observation Programme and by SpaceDataHighway, the European data relay satellite system.
With the continuous developments of high-speed data communication, navigation and positioning, high resolution image acquisition and deep space exploration, the transmission demand of large capacity and high-speed data relay satellite services for inter-satellites is rapidly increasing.
