Three NPO PM spacecraft “Glonass-M” are launched into orbit

On , three navigation satellites “Glonass-M” were orbited form Baikonur launch site. The satellites were developed and produced by the Reshetnev Research and Production association of applied mechanics.

A successful rocket launch put the 37th block of three navigation satellites (## 21,22,23) into 19140 km high circular orbit. The satellite control is maintained by the modernized System Control Center of the Ministry of Defense (Krasnoznamensk) with support of the NPO PM Data Processing Complex.

“Glonass-M” satellites are created to substitute the “Glonass” spacecraft comprising the Russian global navigation satellite system. The 2d generation satellites’ lifespan is already 7 years. Moreover the accuracy of navigation determinations is now 2.5 times better.

This year NPO PM has produced 6 “Glonass-M, the first three were orbited within a block #36 on October 26. By this time the satellites have been put into operation and started their mission.

According to the Federal purpose-oriented program the orbital constellation GLONASS is to come to its nominal configuration (24 satellites) in 2010. The navigation satellite system was designed to operatively and globally provide navigation data and standard time signal for military and civil users.
