Comparison of Ultra-Rapid Orbit Prediction Strategies for GPS, GLONASS, Galileo and BeiDou
Currently, ultra-rapid orbits play an important role in the high-speed development of global navigation satellite system (GNSS) real-time applications. This contribution focuses on the impact of the fitting arc length of observed orbits and solar radiation pressure (SRP) on the orbit prediction performance for GPS, GLONASS, Galileo and BeiDou. One full year's precise ephemerides during 2015 wer...
متن کاملInitial Results of the Precise Orbit Determination for the New-Generation BeiDou Satellites (BeiDou-3) Based on the iGMAS Network
By August 2016, 5 new-generation BeiDou satellites (BeiDou-3) have successfully been launched. The observations of a very limited number of 9 International GNSS (Global Navigation Satellite System) Monitoring and Assessment Service (iGMAS) stations and 52 Multi-GNSS Experiment (MGEX) stations from 16 July to 14 August 2016 are processed to determine the orbits of BeiDou-3 and BeiDou-2 satellite...
متن کاملEstimation of Differential Inter-system Biases between the Overlapping Frequencies of Gps, Galileo, Beidou and Qzss
Multiple global and regional navigation satellite systems are currently being developed. In addition to the already available GPS and GLONASS constellations, Galileo and BeiDou satellites have been launched, as well as one QZSS satellite and other regional satellites. At the same time GPS and GLONASS are being modernized. Highprecision positioning applications that rely on carrierphase ambiguit...
متن کاملPrecise Orbit Determination of BeiDou Satellites with Contributions from Chinese National Continuous Operating Reference Stations
The precise orbit determination (POD) for BeiDou satellites is usually limited by the insufficient quantity and poor distribution of ground tracking stations. To cope with this problem, this study used the GPS and BeiDou joint POD method based on Chinese national continuous operating reference stations (CNCORS) and IGS/MGEX stations. The results show that the 3D RMS of the differences of overla...
متن کاملGlobal Ionospheric Modelling using Multi-GNSS: BeiDou, Galileo, GLONASS and GPS
The emergence of China's Beidou, Europe's Galileo and Russia's GLONASS satellites has multiplied the number of ionospheric piercing points (IPP) offered by GPS alone. This provides great opportunities for deriving precise global ionospheric maps (GIMs) with high resolution to improve positioning accuracy and ionospheric monitoring capabilities. In this paper, the GIM is developed based on multi...
