| Abstract: | Combined GPS/GLONASS can increase the accuracy and reliability of positioning especially in some applications with many impediments.Due to the atmosphere delay,the commonly used methods for processing short distance baselines can not be implemented in long distance baselines.In this paper,a new data processing strategy for long distance baselines is proposed,which uses the properties of some combination observables of combined GPS/GLONASS and distance baselines may come to the order of 10 -8 and combined GPS/GLONASS improves the accuracy over that of GPS_only positioning,which brings benefit to crust deformation monitoring and research on geodynamics. |
