The second satellite to join the constellation that forms the European Data Relay System (EDRS) was launched by Arianespace on 06 August, hh:mm.  The satellite was launched on board an Ariane 5, together with a second passenger, Intelsat 39, from Europe’s Spaceport in Kourou, French Guiana.

EDRS enables people to observe the Earth almost live, accelerating responses to emergency situations and spurring the development of new services and products, to create jobs and increase prosperity.

EDRS – dubbed the ‘SpaceDataHighway’ by its private operator, Airbus – uses innovative laser technology to dramatically cut the time needed for Earth observation satellites, to deliver information to the ground.

The latest satellite, called EDRS-C, will operate in geostationary orbit, at 31 degrees East longitude. It will join its sister EDRS-A, launched in January 2016. The satellites can transmit data at a rate of up to 1.8 Gbit/s.

The geostationary position, higher than typical low-Earth orbiting observation satellites, will enable the constellation to maintain an almost constant connection with the low-Earth orbiting satellites that could otherwise only transmit their information when in direct line-of-sight with their ground stations, which introduces delays of up to 90 minutes.

About the European Space Agency

The European Space Agency (ESA) provides Europe’s gateway to space.
ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.

ESA has 22 Member States: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Slovenia is an Associate Member.

ESA has established formal cooperation with six Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement.

By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country. It is working in particular with the EU on implementing the Galileo and Copernicus programmes as well as with Eumetsat for the development of meteorological missions.

ESA develops the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities. Today, it develops and launches satellites for Earth observation, navigation, telecommunications and astronomy, sends probes to the far reaches of the Solar System and cooperates in the human exploration of space. ESA also has a strong applications programme developing services in Earth observation, navigation and telecommunications.

The EDRS satellites can then beam the information back to Earth in almost real time. Since the end of 2016, EDRS has, on a daily basis, been transmitting images of Earth acquired by the Copernicus programme’s four Sentinel observation satellites. It is also due to relay information from the International Space Station once a new antenna is installed on the outside of Europe’s Columbus laboratory.

The EDRS-C satellite has been manufactured by OHB System AG based on a SmallGEO Platform. EDRS-C also hosts a Ka-band payload called HYLAS 3, which is designed to provide satellite communications services over Africa and the Middle-East. HYLAS 3 is owned by Avanti Communications.

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 programmes, stimulating technology developments to achieve economic benefits.
