Satellite availability and positioning performance of uncombined precise point positioning using BeiDou-2 and BeiDou-3 multi-frequency signals
TL;DR: Both the positioning accuracy and the convergence time of BDS-2/BDS-3 joint UC-PPP are improved by approximately over 50%, which indicates that BDS-3 has a great potential to provide high-quality PNT services as other global navigation satellite systems.

Ray-tracing solar radiation pressure modeling for QZS-1
TL;DR: In this paper, a ray-tracing simulation is performed to compute solar radiation pressure (SRP) accelerations in a more realistic manner, and the resulting SRP model is validated through QZS-1 precise orbit determination over a two year data arc covering yaw-steering and orbit-normal attitude regimes.

Clustering Code Biases between BDS-2 and BDS-3 Satellites and Effects on Joint Solution
TL;DR: Wang et al. as discussed by the authors proposed a code bias estimation algorithm, using what they found to be an obvious clustering code bias phenomenon between the BeiDou navigation satellite system (BDS-2 and BDS-3 satellites, leading to the systematic biases existing in the BDS-2+3 joint solution.
Journal ArticleDOI
The ADOP and PDOP: Two complementary diagnostics for GNSS positioning
TL;DR: It is shown that the ADOP and PDOP have distinct behaviors, an important consequence of which is that one can have time periods with small PDOPs, and thus seemingly good geometry for precise positioning, but at the same time large ADOP's, thus showing that successful ambiguity resolution and therefore precise positioning will not be possible.

LEO–BDS–GPS integrated precise orbit modeling using FengYun-3D, FengYun-3C onboard and ground observations
TL;DR: In this paper, three integrated precise orbit determination (POD) schemes with the individual LEO and a combination of two LEOs are designed to investigate the contribution of the new FengYun-3D satellite.
