Completed testing navigation systems for the new spacecraft – RIA Novosti

MOSCOW, April 8 – RIA Novosti RSC specialists “Energy” completed the flight tests of the system of autonomous satellite navigation (ASN) for spacecraft of the new series “MS Soyuz” and “Progress MS” as well. for manned transport spacecraft (PTC) of new generation, said the corporation.

The new system of autonomous navigation, working with signals satellite navigation systems GLONASS and GPS, provides a definition of the parameters of the ship’s orbit, its orientation, a decision relative navigation tasks when approaching the ISS.

“Flight tests are successfully completed, now there is a preparation of documentation for entry into regular operation of the system. in the world there is no such satellite systems for space vehicles able to solve navigation tasks with such a high accuracy “, – said the head of sector RSC” Energia “, one of the developers of the system, Mikhail Mikhailov.

He stressed that the set of equipment ASN, mounted on the spacecraft” Progress MS “and” Union of MS ” worth 5-6 times cheaper than foreign analogues. To achieve cost reduction failed due to “replace many hardware to software solutions”.

The structure of ACH input is set to ship four multi-directional reception antennas, 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 of the signals from 20 to 24 navigation satellites. This arrangement provides a high accuracy and reliability.

The system allows you to define the parameters of the orbit of the ship to the coordinates to within 5 meters, regardless of its orientation. The accuracy of the orientation is 0.5 degrees. Relative coordinates are calculated when approaching to within 1 meter, but there are plans to bring it up to 3-4 cm, noted in RSC “Energia”.

The unique characteristics are achieved, in particular, due to the system’s ability to work simultaneously two satellite groups: the GLONASS and GPS. Most of Western space navigation systems work exclusively with GPS.
