The EDRS-C satellite was launched aboard an Ariane 5
EDRS-C successfully launched
6 August 2019
The second satellite to join the constellation forming the European Data Relay System (EDRS) was successfully launched.
The satellite was launched aboard an Ariane 5 from the European Space Port in Kourou, French Guiana on August 6 at 21:30 CEST (19:30 UTC).

EDRS enables people to observe the earth in near real time, accelerating emergency response and spurring the development of new services and products that create jobs and increase prosperity.
EDRS – dubbed 'SpaceDataHighway' by its private operator Airbus – uses innovative laser technology to dramatically reduce the time required for Earth observation satellites to provide ground information.
Satellites can transmit data at a rate of up to 1.8 Gbit / s.
The latest satellite, called EDRS-C, will operate in geostationary orbit. It will join your brother EDRS-A, which was released in January 2016.
The geostationary position, higher than Earth's low-orbiting observation satellites, will allow the constellation to maintain an almost constant connection with low-orbiting satellites that could only transmit their information when in direct line with their earth stations, which introduces delays of up to 90 minutes.
Instead, EDRS satellites can then transmit the information back to Earth in near real time.
Since late 2016, EDRS has been transmitting daily Earth imagery acquired by the four Sentinel observation satellites of the Copernicus program.
It is also planned to relay information from the International Space Station as soon as the necessary equipment is installed outside the Columbus laboratory in Europe.
EDRS is a new, independent European satellite system and is a public-private partnership between ESA and Airbus as part of ESA's efforts to federate industry around large-scale programs, spurring technological developments for economic benefits. .
