Abstract. A modified algorithm of nanosatellite uniaxial attitude estimation based on the analysis of geometric visibility of navigation satellites of the Global Navigation Satellite Systems GLONASS and GPS is presented. The algorithm modification consists in changing the navigation antenna pattern width. The proposed algorithm allows to increase the uniaxial attitude determination accuracy.
Keywords: nanosatellite, geometric visibility, GLONASS, GPS, antenna pattern
