Receiver Autonomous Integrity Monitoring (RAIM) has been successfully used for fault detection and exclusion in aviation applications. For airborne environment, the Geometric Dilution Of Precision (GDOP) and pseudo-range measurement quality is good. However, for urban canyon environment the GDOP may increase much and the pseudo-range measurement may contain huge multipath error. In this case, the...
Carrier phase Ambiguity Resolution (AR) is the key to GNSS attitude determination. The baseline length is a readily available and widely used constraint. The traditional long-short baseline AR method resolve the integer ambiguity using the baseline length constraint on condition that the short baseline length is shorter than half of the carrier wavelength. In this contribution, we propose the Dual...
With the rapid development of GNSS receiver's performance and the coming of each GNSS's Full Operational Capability (FOC), compatibility and interoperability must be one of the developing trends of GNSS positioning. In this study, a compatible Kalman filter was designed. The performances of the compatible Kalman filter (KF) and traditional Least Square (LS) were compared through BDS, GPS, and GLONASS...
