Russian Rocket Proton-M European Telecommunications Satellite

Launched from the Baikonur Cosmodrome in Kazakhstan started a Russian rocket Proton-M with a European telecommunications satellite, which is to enter into the composition of a new EDRS system (European Data Relay System).EDRS system, developed over 10 years by the European Space Agency (ESA) and is intended to serve primarily a very quick transfer to ground stations data and images of the surface of our planet. I mean especially with photos of natural disasters areas such as flooding and earthquakes that will allow the assessment of the dimensions and consequences of the disaster.

The system is a major step forward compared to the existing telecommunications satellites. Instead transfer photos directly on the ground, which is possible only for a very limited time to fly across the receiving antenna (usually about 10 minutes), satellite transmit photo laser transmitter to the second satellite located much higher. geostationary orbit. Only the satellite will transmit pictures to the ground.

ESA has placed on low orbits around the Earth two satellites for direct observation, which are equipped with optical laser apparatus. They can now transmit data via the new satellites that will be placed at a height of 36 thousand. km above the equator.

Project leader Michael EDRS Witting stressed that the “communication” satellites in orbit using a laser is a difficult and complex task. You have to hit another laser satellite radius from a distance of more than 40 thousand. km, which can be likened to hitting a coin on the other side of the Atlantic, “he said. System operator and owner of commercial satellites is established in Paris, Eutelsat Corporation.
