Russia successfully launched another satellite for their GLONASS network on April 26th,
The GLONASS-M was launched into orbit atop a Soyuz 2-1b Fregat-M booster and will shortly begin a long testing phase before it is activated for service.
GLONASS-M is the second generation of GLONASS satellite and has an enhanced operational lifetime of 7 years. Each satellite consists of a large, dual panel solar array and 25 L-Band channels broadcasting in tow frequency bands between 1240 and 1602MHz. Atomic clocks provide the reference timing signals accurate to more than 1000 nanoseconds.
Upto 3 GLONASS satellites can be launched on one rocket when using the Proton family of boosters but only single satellite launches are possible using Soyuz 2-1b.
Once commissioned, this satellite will join the existing fleet of 23 active satellites.
