Galileo Ionospheric Correction Algorithm Integration into the Open-Source GNSS Laboratory Tool Suite (gLAB)
TL;DR: In this article, the authors compare the performance of the two implementations of NeQuick-G in terms of accuracy, consistency, availability, and execution time, and conclude that both implementations perform equivalently.
Journal ArticleDOI
BDS near real-time maneuver detection based on triple-differenced phase observations
TL;DR: In this paper , the authors presented a near real-time maneuver detection method for BeiDou Navigation Satellite System (BDS) based on triple-differenced phase observations, which can automatically detect the exact start and end times of satellite orbital maneuvers.
Journal ArticleDOI
Generation of DFMC SBAS corrections for BDS-3 satellites and improved positioning performances
TL;DR: A novel DFMC SBAS correction generation approach for BDS-3 satellites is proposed in which only clock offset corrections are calculated and the effectiveness of the proposed approach is validated using measurements from mainland China.
Journal ArticleDOI
Construction of a BDSPHERE solar radiation pressure model for BeiDou GEOs at vernal and autumn equinox periods
TL;DR: In this paper, the authors proposed to replace SPHERE with BDSPHERE for the BeiDou System (BDS) during both equinox and non-equinox periods.
Journal ArticleDOI
Impact of the Initial State on BDS Real-Time Orbit Determination Filter Convergence
TL;DR: Experimental results show that a proper a priori STD of initial state can significantly accelerate the orbit convergence, while a loose a prioru STD takes more than 10 h to converge in the radial direction for the BDS GEO/IGSO/MEO satellites.
