Abstract:	Honeywell and the Leningrad Scientific Research Radiotechnical Institute (LSRRI) have been conducting a number of GPS and GLONASS receiver tests in cooperation with Northwest Airlines and The All Union Scientific Research Institute of Radio Equipment (AUSRIRE) in the USSR. The Soviet built receiver ASN-16, the Honeywell HG2021 GPS Sensor Unit (GPSSU) and the HG1050 GPS/Inertial Reference Unit (GPIRU) have been tested under static conditions with fixed antennas in the lab and under the dynamic conditions of a Northwest Airline 747- 200 freighter aircraft. This paper presents the results of the GPS/GLONASS combined system evaluation tests. Navigation data from flights sampled worldwide are analyzed and the results are used to determine the relation between the WGS-84 and SGS-85 earth fixed coordinate systems. The consistency of the data is discussed. The availability of the GLONASS satellites in relation to the almanac is evaluated. Integrity coverage results based on RAIM using the future GPS and GLONASS constellations are also presented
