Positioning performance assessment using DGNSS satellite based augmentation system [SBAS] with different satellite combination / Emir Asyrawi Rosdy

Differential Global Navigation Satellite Systems (DGNSS) uses a fixed, ground-based reference station network which enables the broadcasting of differential information to the user to improve the accuracy of the position. It is important to provide a good indication of positioning and navigation per...

It is important to provide a good indication of positioning and navigation performance by the availability of four-constellation integration with GPS, GLONASS, BeiDou, and Galileo. This study is to differentiate the accuracy of the results given between single satellite, double satellite, and triple satellite observation, which are GPS, GPS and BeiDou, and GPS GLONASS, and BeiDou using DGNSS Satellites Based Augmentation System (SBAS), that delivers the corrections and improved GNSS services through broadcasting messages from a geostationary satellite. Twenty-four hours static observation are performed with one DGNSS receiver for single, double, and triple satellite combination.

Statistical analysis was done to support the comparison of positioning data, which is descriptive analysis, T-Test analysis, horizontal error analysis, vector distance analysis and normal distribution graph. The positioning comparison between single, double, and triple shows that the deviations from the reference coordinate for single satellite combination do not exceed 1.963 m for the northern component, 1.649 m for the eastern component. In the case of double satellite combinations, the deviation for a horizontal component is much smaller which it is 1.586 for northing and 1.586 m for easting while triple satellite combinations horizontal component do not exceed 1.163 m for northing and 1.576 m for easting.
