Abstract. By the beginning of 1996 the Russian Global Navigation Satellite System (GLONASS) constellation was completely deployed, although several satellites have already been decommissioned since then. With 17 satellites in operation (status as of 21 December 1997, although two of them are unusable and one is a non-operative spare), GLONASS is now an alternative and a complement to GPS. We present an evaluation of the current status of the GLONASS system, paying particular attention to its possible geodetic applications. Data from several receivers were used for this evaluation, including data from GPS receivers in order to allow for a comparison between GLONASS and GPS. We tested the quality of the geodetic observables, the consistency of the broadcast orbits, the single-point positioning results, and we also looked at multipath errors and cycle slips in our GLONASS data. In general the GLONASS performance has been found to be very satisfactory, even better than GPS in aspects such as single-receiver positioning or in the quality of the second-frequency pseudo-ranges due to the degradation of the GPS measurement quality under selective availability and anti-spoofing.
