GLONASS Integrity And Reliability Assessment From Operational Experience of 1995

V.I. Dumev and Yu.N. Silantiev

Abstract:	This paper reviews official annual data on GLONASS integrity and its availability. It provides information about the present technical status of the GLONASS system, expected improvements in system integrity and availability, and comparative estimates of integrity and availability for the GPS and GLONASS systems. The Russian GLONASS Space Navigation System has been fully deployed and it was in normal operation during 1995 with 24 space vehicles (SVs) in its orbital block. The GLONASS system comprises three segments: . space segment; . control and monitoring segment; . user equipment segment. The GLONASS space segment consists of 24 satellites on circular orbits of 19100 km high with declination of 64.8” and circulation period of 11 hours 15 minutes in three orbit planes. The orbit planes are spaced by 120’ in longitude. Each orbit plane comprises 8 satellites with a regular shift of 45” in latitude argument. Besides, the planes themselves are shifted relative each other in latitude argument by 15“. The orbital configuration is shown in Fig 1.
