SpaceDataHighway achieves 10,000 connections

MUNICH, May 20, 2018

The SpaceDataHighway system, a public-private partnership between the European Space Agency and Airbus and the world’s first ‘optical fibre in the sky’ based on cutting-edge laser technology has achieved 10,000 successful laser connections.

 The reliability rate has reached 99.8 per cent, and during the first one and a half years of routine operations these successful connections have downloaded more than 500 terabytes of data.

The system’s satellites are designed to lock on to low-orbiting satellites via laser and collect their data as they travel in low Earth orbit scanning the Earth. From its position in geostationary orbit, the SpaceDataHighway acts as a relay, transmitting the large quantities of data acquired by these observation satellites down to Earth in near-real time at a speed of 1.8 Gbit/s, instead of storing the data on board until the satellites pass over their own ground station.

The establishment of the laser connections is controlled by the SpaceDataHighway’s Mission Operation Centre which operates 24 hours a day, seven days a week at Airbus premises near Munich. Operators receive transmission requests from customers, programme the space and ground segment and monitor the performance of communications.

“While 2017 has been a year of ramp-up for the system, we have now reached more than 1,000 connections per month in 2018 with a very high level of reliability,” said Hughes Boulnois, head of the SpaceDataHighway programme at Airbus Defence and Space. “The total amount of data transferred is equivalent to around 100 million MP3 music files, but the transmission capacity of the SpaceDataHighway goes far beyond that.”

Each day, the SpaceDataHighway is capable to relay up to 40 terabytes of data acquired by observation satellites, Unmanned Aerial Vehicles or aircraft, to Earth. It is currently used by the European Union’s Copernicus programme, but its capacities could be used by many more customers.

In 2019, the system will also relay information from the Columbus module of the International Space Station (ISS). From 2020 the Pleiades Neo satellites will begin to use the SpaceDataHighway. – TradeArabia News Service
