A laser communications terminal prototype to demonstrate this vision is currently being developed by satellite manufacturer Airbus, working in partnership with the Netherlands organization for app<\/a>lied scientific research (TNO). The project is co-financed by Airbus, TNO and the Netherlands Space Office.<\/p>\n

The work forms part of ESA’s program for secure and laser communication technologies\u2014which is known as “ScyLight” and addresses optical as well as quantum communication.<\/p>\n

Optical communication technologies\u2014which use lasers\u2014offer unprecedented transmission rates, data security and resilience, and are set to revolutionize satellite communications.<\/p>\n

Optical communication is extremely hard to intercept because, in comparison to radio frequencies, it uses much narrower beams.<\/p>\n

The laser communication terminal demonstrator developed by Airbus and partners will be designed, constructed and tested under laboratory conditions by the end of 2021.<\/p>\n

The following year, the system\u2014called UltraAir\u2014will be installed in ESA’s optical ground station in Tenerife, Spain and tested in a communication link with another laser terminal on board the Alphasat telecommunications satellite, which is in geostationary orbit some 36 000 kilometers above Earth.<\/p>\n

For the final verification, the UltraAir demonstrator will be integrated on an aircraft for flight testing by mid-2022.<\/p>\n

The technology<\/a> demonstrator will pave the way for a future UltraAir product which could reach data transmission rates of several gigabits-per-second while providing anti-jamming technology and a low probability of interception.<\/p>\n

In the longer term, the devices will allow airline passengers to establish high-speed data connections using evolutions of the European Data Relay System (EDRS), also known as the SpaceDataHighway.<\/p>\n

As of today, EDRS is designed to accelerate the flow of information from low-Earth orbit satellites back to people on the ground. It uses lasers to relay data back to Europe in almost real time.<\/p>\n

EDRS is an independent European satellite system, and is a Partnership Project between ESA and Airbus, as part of ESA’s efforts to federate industry around large-scale programs, stimulating technology developments to achieve economic benefits.\n <\/p>\n\n
