Estimating and Analyzing Long-Term Multi-GNSS Inter-System Bias Based on Uncombined PPP
Sensors, 2020 With the development of precise positioning with multi-GNSS, the inter-system bias (ISB) has become an issue that cannot be ignored. ISB is introduced from the differences among satellite reference clocks and different receiver hardware delay biases.

Long-term and short-term stability characteristics of receiver inter system bias for BDS3/BDS2
Geodesy and Geodynamics, 2023 The study of inter-system bias (ISB) is important for multi-system fusion and the performance of different signal compatibility. In this paper, the stability of ISB at the BDS3/BDS2 receiver end is calculated and analyzed for different time spans (DOY ...
