Satellite "Glonass-M" launched for maintenance due to the increased error
One of the navigation satellites "Glonass-M" had to temporarily withdraw for maintenance. The reason is a significant excess of the error rate, which was discovered after analyzing the daily monitoring data. During decommissioning, the satellite was located above southern Africa.
The device in question was launched into orbit on March 2, 2010; it was commissioned on March 28. The satellite number is 731. The global network of monitoring stations includes Russian stations of the SDCM network (stations in Russia and 2 stations in Antarctica) and stations of foreign organizations (IGS, Euref, TrigNet, RBMC, etc.).
Glonass-M is a second-generation navigation satellites, which have been used since 2001. In total, 46 satellites have been launched into orbit. The system includes 26 vehicles, 24 are used. Third-generation GLONASS-K and GLONASS-K2 devices are currently being prepared for the aging satellites.
It is worth noting that one of the satellites of the Glonass-M series was put into orbit on June 17, 2018 using the Soyuz-2.1b rocket. On November 3, another satellite was launched using the same rocket.
