Glonass-K’s OCS undergoes development tests

The JSC “Academician M.F. Reshetnev “Information Satellite Systems” is currently conducting development tests of the onboard control subsystem designed for the new-generation navigation spacecraft Glonass-K.

At present the satellite’s onboard computer, TCR and the control unit are being subjected to a number of rigorous tests. The originality of the satellite’s onboard control subsystem consists in the use of new components and programmable devices which allow saving in weight.

The Glonass-K is an advanced spacecraft of unpressurized design with the projected service life of 10 years. In comparison with the Glonass-M satellite, it will send out a greater number of navigational signals. Besides, the spacecraft’s payload will include additional equipment intended for retransmission of signals from ships and aircraft suffering distress.

The launch of the first Glonass-K spacecraft is scheduled for 2010.
