Influence of Inter-System Biases on Combined Single-Frequency BDS-2 and BDS-3 Pseudorange Positioning of Different Types of Receivers

Remote Sensing
The BeiDou Navigation Satellite System (BDS) has developed rapidly, and the combination of BDS Phase II (BDS-2) and BDS Phase III (BDS-3) has attracted wide attention. It is found that there are code ISBs between BDS-2 and BDS-3, which may have a certain

A Priori Modeling and Differentiated Parameter Reduction of ECOMC Solar Radiation Pressure Parameters for BeiDou Satellites Based on Driving Attribution [PDF]

Sensors
Mismodeling of solar radiation pressure (SRP) is a leading error source in BeiDou precise orbit determination (POD), yet the temporal predictability of the empirical SRP parameters remains poor.
