Incorporating GLONASS into Aviation RAIM Receivers
نویسندگان
چکیده
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.

In the near future, many more navigation satellites with dual frequency L1 and L5 will be deployed. The increased number of satellites and the possibility of mitigating the ionospheric delay using dual frequency have opened the door to the possible use of RAIM for vertical guidance. For this purpose, several Advanced RAIM (ARAIM) algorithms have been proposed. Extensive simulation studies have ...

In the 1980s, Global Positioning System (GPS) receiver autonomous integrity monitoring (RAIM) was proposed to provide the integrity of a navigation system by checking the consistency of GPS measurements. However, during the approach and landing phase of a flight path, where there is often low GPS visibility conditions, the performance of the existing RAIM method may not meet the stringent aviat...
