SESAT marks a 15-year milestone in orbit

On April 18, 2015 ISS-Reshetnev Company celebrates 15 years since the launch of a geostationary telecommunications satellite Sesat, developed and built for a European satellite operator EUTELSAT.

A contract to design and manufacture the Sesat satellite (Siberian-European Satellite) was signed on August 4, 1995 and became the first international satellite construction project in the history of the Reshetnev Company and the whole Russian satellite building industry. It was the first turn-key satellite project successfully implemented by a Russian company in compliance with the global aerospace industry standards.

The launch took place on April 18, 2000.

Sesat was the first satellite designed with a 10-year active lifespan. To build the satellite, ISS-Reshetnev Company pioneered a new scheme which had been never applied in the Russian aerospace industry before – the satellite was made up of two separate modules: a payload module and a service systems module (satellite platform). It was also the first time the company developed a computational model of a data-relaying satellite.

Within the framework of the Sesat project ISS-Reshetnev Company was responsible for the manufacture of the service systems module, assembly and all kinds of tests to be performed on the satellite and launch of Sesat into the orbit. As well as that, the Reshetnev Company built up the ground control complex and provided satellite control training to the customer representatives.

In accordance with the contract signed with the European operator EUTELSAT, ISS-Reshetnev technicians provide ongoing operations support to the customer.

The Sesat satellite has already outlived its original design life by five years. It is currently stationed at the position of 14.5 degrees East longitude from which it continues carrying out its mission providing television broadcasting, Internet access, data transmission, fixed and mobile communications services to European countries.
