Roscosmos has announced plans to improve the location accuracy of the Russian global navigation satellite system GLONASS to 10 cm after 2030. This was announced on Saturday, June 5, RIA Novosti reports with reference to the materials of the state corporation posted on the public procurement portal.
The document requires that in order to ensure the accuracy, availability and integrity of the navigation of the satellite system after 2030, the error in determining the location due to the space segment should be 0.1 m.
In addition, it is noted that the advanced GLONASS orbital constellation after 2030 may include upgraded high-elliptical satellites "VKK-M", small-sized vehicles "MNKA-M", including additional "DKA", medium-orbit "Glonass-KM" and geostationary "GSO-M".
As a long-term perspective for the development of GLONASS, it is planned to consider the period until 2050, when the orbital grouping (OG) of the system will be formed on the basis of an innovative type of navigation spacecraft (SC).
By this time, as indicated in the materials, the next generation of spacecraft (Glonass-KM spacecraft) or modifications, as well as, possibly, a new type of navigation spacecraft, should be created and implemented.
On April 21, Nikolay Testoyedov, General Director of the Reshetnev Information Satellite Systems Company, announced that the first new-generation navigation satellite, Glonass-K2, will be launched into orbit in the fourth quarter of 2021.
Glonass-K2 is a new generation of navigation satellites of the GLONASS system.
In February 2021, the general director of Roscosmos, Dmitry Rogozin, stated that the accuracy of GLONASS satellites is 2.6 m, and with the advent of the new generation of Glonass-K2 devices, it will improve to 1.3 m.
In January , it was reported that this year it is planned to launch five GLONASS navigation satellites into orbit.
