Impact of elevation mask on multi-GNSS precise point positioning performance
TL;DR: In this article, the authors analyzed the impact of elevation masks on the performance of multi-GNSS kinematic PPP and showed that the PODP increases as the elevation mask increases.

GPS, GLONASS, and Galileo orbit geometry variations caused by general relativity focusing on Galileo in eccentric orbits
TL;DR: In this article, the authors measured the variations of orbit size and shape of GPS, GLONASS, and Galileo satellites in circular and eccentric orbits and compared the results to the theoretical effects using three years of real GNSS data.

Continuous precise ephemerides for Beidou-2 maneuvered satellites based on a new thrust force model
Jing Qiao,Jing Qiao,Wu Chen +2 more
TL;DR: In this article, the authors presented a thrust model based on the thrust behavior of Beidou-2 satellites detected in previous study, and then determined the precise orbit by estimating the extra thrust model parameters, together with other orbit parameters of initial satellite state and solar radiation pressure (SRP).

Positioning bias of different frequency observations in double-differenced relative positioning
TL;DR: In this paper, the double-differenced positioning bias of different frequency observations (PBDFO) in a code division multiple access (CDMA) signal system is analyzed based on real-time kinematic (RTK) positioning using raw observations at different frequencies.
