A Report on the Second Meeting of the GLONASS-GPS Interoperability Working Group

James A. Slater, Pratap Misra

Abstract:	There is considerable interest in the civil community in using the combined set of signals available from GPS and GLONASS. With the constellations combined, all users would have amply redundant measurements from 10 or more satellites. GLONASS also offers an extra attraction, at least in the short run: Unlike GPS, GLONASS signals available for civil use are not degraded purposefully. GPS and GLONASS are autonomous systems, each with its own references for time and space. Before measurements from the two systems can be combined, a connection must be established between the two time scales and the coordinate frames. The differences in coordinate frames and time references are the two best-known examples of GPS-GLONASS interoperability problems. The user community is diverse, and there are other issues, too. The Institute of Navigation (ION) initiated a working group in 1996 to serve as a forum for discussion and resolution of these issues. The first meeting of the GLONASS-GPS Interoperability Working Group (G-GIWG) was held in conjunction with ION GPS-96 in Kansas City, MO, on September 20, 1996. The ION offered its Web site to facilitate communications among the working group members, and proposed to continue the discussion at future meetings of the Satellite Division. Accordingly, the second meeting of the G-GIWG was held on September 19, 1997, as a part of ION GPS-97.
