Russian Space Systems (RKS, part of the Roscosmos State Corporation) has completed the formation of a ground infrastructure for a high-precision complex for wide-area functional supplementation of global navigation satellite systems based on the development of a differential correction and monitoring system – a network of 53 unified measurement collection stations has been created.
The network of stations is designed to receive information from navigation satellites, as well as to process and provide corrective data to consumers in Russia and the CIS countries. All in all, 46 stations are located on the territory of Russia, 18 of which are located at the facilities of PJSC “Rostelecom” branches, the last station of the ground infrastructure has recently started operating in Yekaterinburg. 4 more stations were built in the CIS countries and 3 in Antarctica.
A high-precision complex for wide-area functional supplement to global navigation satellite systems was created by order of the State Corporation “Roscosmos” and is an important element in improving the accuracy of the GLONASS system. All navigation information received by the stations is transmitted to processing centers.
Unified measurement collection stations receive open radio navigation signals GLONASS, signals of foreign navigation satellite systems and provide consumers with additional information to improve the accuracy and reliability of determining the speed of movement, the accuracy of time reference, as well as spatial coordinates. The output information is brought to consumers through special channels via geostationary communication satellites and via the Internet. The stations are provided with uninterruptible power supply systems and can work in an autonomous mode for a long time.
