Autonomous navigation system for future satellites

ISS-Reshetnev Company has completed mechanical tests on a prototype model of a recently developed autonomous navigation system.

The autonomous navigation system intended for satellites yet to be built is a joint effort between ISS-Reshetnev Company and scientists from the Tomsk State University of Control Systems and Radioelectronics (TUSUR). A prototype model of this instrument was delivered to ISS-Reshetnev from TUSUR to undergo one of the most crucial stages of experimental testing when the instrument’s ability to withstand mechanical loads during and after launch is checked.

The new instrument is based on Russian components. It’s important to say that this instrument has a valuable advantage over previous versions of autonomous navigation systems – its reduced size and weight.

The next-generation autonomous navigation system will enable satellites calculate their real-time position in orbit using navigation signals from GLONASS, GPS, Galileo and BeiDou systems not depending on data uplinked from the ground. This solution is expected to increase positioning accuracy for communications satellites and make their tracking and control more simple and effective.
