“Flight tests have been successfully completed, now we are preparing documentation for putting the system into normal operation. There are no such satellite systems for spacecraft in the world capable of solving navigation tasks with such high accuracy ”,quoted by the press service of one of the developers of the system Mikhail Mikhailov.
“The set of ASN equipment installed on the Progress MS and Soyuz MS spacecraft is 5-6 times cheaper than their foreign counterparts. We managed to achieve cost reduction by replacing many hardware with software solutions, ”he stressed.
It is noted that "a new autonomous navigation system that works with signals from GLONASS and GPS navigation satellite systems is being installed on the Soyuz MS and Progress MS series spacecraft, and is also expected to be installed on a new generation manned transport ship."
According to the information, “the system determines the parameters of the orbit of the spacecraft, its orientation, the solution of the relative navigation problem when approaching the ISS”.
“ASN includes four multidirectional receiving antennas installed on the ship, which are mathematically combined into one virtual antenna with a wide field of view. This allows for any orientation of the spacecraft to conduct continuous measurements on signals from 20 to 24 navigation satellites. This scheme provides high accuracy and reliability, “- said in a release.
According to the press service, “the system allows you to determine the parameters of the orbit of the ship by coordinates with an accuracy of 5 meters, regardless of its orientation. Orientation accuracy is 0,5 degrees. Relative coordinates at convergence are calculated to the accuracy of 1 m, but in the future it is planned to bring it to 3-4 cm. ”
Unique characteristics have been achieved, in particular, “due to the ability of the system to work simultaneously with two satellite constellations: GLONASS and GPS, while most Western space navigation systems work exclusively with GPS,” the corporation noted.
