In a world where we have satellite radio, satellite TV, satellite internet service, GPS, and other services delivered to us from above its nice to know that someone is pushing this technology to make our lives better and to provide additional security for everyone.
Recently, the European Data Relay System began servicing Europe’s Copernicus program using the first optical satellite communications network. This is a big step toward creating a data network of satellites that can deliver near-realtime data around the world.
The European Space Agency has been working on this network for some time now. One of the major problems that this system solves is the information delay in lower orbiting satellites of the Copernicus program’s Sentinel satellites. These satellites are providing observational data of planet Earth to help track climate change and range of other goals including maritime surveillance, disaster response, and security. The issue is that the low orbiting satellites have communication delays. They can only relay information back to ground-based stations for 10 minutes during their 100-minute orbit. Causing up to a 90 delay in information. This can cause real problems when accurate information is needed to help save lives. The solution is the EDRS which uses high orbiting geostationary satellites and optical communications to retrieve information from low orbiting satellites at a rate of 1.8 Gbit/s and then send it down to Earth. The result is a quasi-realtime communication between the observational satellites and the ground.
The infographic below explains how the system works and shows where it is headed in the near future.
