Incorporating GLONASS into Aviation RAIM Receivers

Abstract:	Recently the Russian government issued a mandate on the use of their GLObal NAvigation Satellite System (GLONASS) for Russian operated aircraft [1]. There is some concern and uncertainty both in exactly what is required to satisfy the mandate and how best to conform to it. GLONASS recently re-established full operating capability and has 24 operational satellites in orbit. The addition of a second full constellation is, potentially, very beneficial to satellite navigation of aircraft. However, the GLONASS satellites do not have the same performance characteristics as the Global Positioning System (GPS) satellites. Therefore it is essential to understand these differences in any algorithm that seeks to determine a safe position based on the combined performance of these two systems.
