Estimating and Analyzing Long-Term Multi-GNSS Inter-System Bias Based on Uncombined PPP [PDF]
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.

Detecting and Repairing Inter-system Bias Jumps with Satellite Clock Preprocessing [PDF]
Remote Sensing, 2020 The key to performing successful multi-GNSS (Global Navigation Satellite System) precise point positioning is calibrating ISB (inter-system bias) in different systems. We can use the method of modeling to eliminate the ISB error.
