Precision R-100 GPS/GLONASS Time Transfer

Anushia Balendra and James Danaher

Abstract:	The Russian GLObal NAvigation Satellite System (GLONASS) transmits time and frequency reference signals reFerenced to on-board Cesium atomic clocks. The operation capabilities, and transmission frcqucncy of GLONASS syslcm arc quilt similar to GPS and should be able to match time transfer pcrfomrance using GPS. GLONASS satellites also transmit P code signals on both Ll and L2 without Anti-Spoofing (AS) encryption. Both GPS and GLONASS signals are used in the 3s Navigation R-100 rcceivcr for precision time- keeping. The absence of Selective Availability (SA) on the GLONASS signals allow GLONASS IIIC~SII~C~CIIIS to bc directly used for precision rcn I Lime frcqucncy rcfercncc applications. This paper prcscnts the GLONASS Ll C/A code based time transfer and real time frequency measurement results the of 3s Navigation RlOO Integrated GPSlGLONASS receiver.
