Accuracy assessment of positioning based on single and MULTI-GNSS

Résumé

Single GNSS Multi-GNSS Precise Point Positioning (PPP) PPPH International GNSS Service (IGS) Global Navigation Satellite System (GNSS) globally gives users 24-hour service of 3D positioning, velocity, and time with the aid of radio signals transmitted from satellites orbiting in space. More satellites present during observation bring improvement in satellite geometry and redundancy which gives better quality of GNSS positioning result. This study aims at testing the positional accuracy of the use of multi-GNSS as compared to using a single satellite. Five International GNSS Service (IGS) stations (MRO1, PTVL, TONG, XMIS, and YAR3) were used for the study and the data obtained from these stations were post-processed using the PPPH software. In the single satellite category, GPS and GLONASS produced similar results with RMSE values of approximately >0.1m in both horizontal and vertical components. On the other hand, the combination of GPS+GLONASS gave the best result in the multi-GNSS category with RMSE values identical to those obtained from the GPS and GLONASS single satellites.
