Abstract

Under contract of the German Ministries of Transport and Defense a GPS/GLONASS/INS test program has been carried out since 1992. Besides other goals, the aim of the project is to investigate the capabilities of GLONASS in comparison to GPS, to realize a combined GLONASS/INS solution and to perform joint processing of GPS and GLONASS raw data. The paper describes the test procedures and will present some of the results of the trials. This includes the comparison of DGPS with standalone GLONASS and GLONASS/INS under different dynamic situations, e.g. driving tests, flight tests, and also the presentation of results of combined GPS/GLONASS data processing, which was successfully achieved in March ´93 for the first time. The results show the potential of the non-SA-degraded GLONASS and the advantage of using both, GPS and GLONASS for combined solutions
