OPERATION OF THE ISS ASN-M, ITS CHARACTERISTICS AND POSSIBLE APPLICATIONS. OUTLOOK FOR THE ASN USE ON SOYUZ AND PROGRESS SPACECRAFTS

摘要

The article describes the International Space Station satellite navigation system ASN-M, its configuration and structure, applications and accuracy characteristics. The results of ASN-M flight tests show that achievable orbit formation precision is 3-5 m; orbit forecast precision for an orbit is 20-30 m. The results are presented from the ATV rendezvous with ISS in April, 2008, which was the world's first rendezvous using ASN measurements. Based on the experience in the development and operation of the ASN-M, we propose a preliminary model of ASN-K for Soyuz and Progress spacecraft aimed to solve problems of navigation, attitude determination and rendezvous. The ASN-K structure is presented as well as its key features. We propose the general framework for solving current problems. The simulation results are reported for ASN-K operating in navigation, attitude determination and rendezvous modes.
