Beidou Receiver IFB Calculation and Stability Analysis

The Beidou Navigation Satellite System (BDS) has been providing navigation services for customers all over the whole Asia-Pacific region since Dec, 2012. The international GNSS Monitor and Assessment System (iGMAS) has constructed more than 20 Multi-GNSS monitoring stations around the world, which provides the research foundation for the high precision application of BDS. The Inter-Frequency Bias (IFB) of the receiver is the main error affecting the high precision application of the navigation satellite system. In this paper, a variety of calculation methods for the receiver GPS IFB are analyzed. Using the measured data, we accessed the stability and accuracy of the single-station receiver IFB calculation method for BDS, and proposed some suggestions for the application of this method.
