Glonass system to achieve 5 cm precision by 2030

Consistent with the Glonass navigation system development program, 28 Glonass K2 satellites and six Glonass VKK satellites will be put into orbit by 2030 to achieve the system’s 5 cm precision, Alexey Bolkunov, General Designer of the Glonass office said at the 14th international conference on Trends and Harmonization of the Development of Radio-Navigation Service.

It is planned to launch 20 Soyuz-2.1b and Angara-A5 rockets between 2021 and 2030 to deliver 28 Glonass K2 satellites to the orbit. “In the period until 2024, we will be using the existent satellites to provide basic services, and preparations for the network’s transition to new satellites is due to begin in 2030,” he said.

In addition, six Glonass VKK satellites will be inserted into highly elliptical orbits in 2026 and 2027. “So far, the system’s precision is about ten meters. There is also a high-precision service, for which the high-orbit cluster of VKK vehicles will be deployed. Therefore, we aim to improve the precision […] to about 5 centimeters,” Bolkunov said.

According to him, a new retransmission satellite, Luch, will be launched in 2025 to raise the precision and accessibility of the Glonass system.
