SMALL SATELLITE ATTITUDE DETERMINATION USING NAVIGATIONAL RECEIVER AND MAGNETOMETER

摘要

Algorithmic support of the small-sized movement tracking system for small satellites is considered. In the capacity of the measuring equipment the multichannel single-frequency navigational receiver and the three-axis magnetometer is used. The navigational receiver is used for definition of small satellites mass center motion parameters, and also for an approximate estimation of orientation of phase center of navigational antenna under the analysis of visibility/invisibility of navigation satellites. Integrating schemes of magnitometric and the satellite radio navigational information and the algorithms are described. These researches have been executed within the framework of the grant of the Russian Fund of Basic Researches No 09-08-00842-a. Thanks to the Russian Fund of Basic Researches for financial support of participating in IAC 2009 (RFFR grant No 09-08-08088-3).
