A method of undifferenced ambiguity resolution for GPS+GLONASS precise point positioning
Integer ambiguity resolution is critical for achieving positions of high precision and for shortening the convergence time of precise point positioning (PPP). However, GLONASS adopts the signal processing technology of frequency division multiple access and results in inter-frequency code biases (IFCBs), which are currently difficult to correct. This bias makes the methods proposed for GPS ambi...
متن کاملGPS and GLONASS Integration: Modelling and Ambiguity Resolution Issues
The integration of GPS with GLONASS may be considered a major milestone in satellitebased positioning, because it can dramatically improve the reliability and productivity of said positioning. However, unlike GPS, GLONASS satellites transmit signals at different frequencies, which results in significant complexity in terms of modelling and ambiguity resolution for integrated GPS and GLONASS pos...
متن کاملGlobal Positioning System Integer Ambiguity Resolution without Attitude Knowledge
In this paper, a new motion-based algorithm for GPS integer ambiguity resolution is derived. The algorithm represents the GPS sightline vectors in the body frame as the sum of two vectors, one depending on the phase measurements and the other on the unknown integers. The vector containing the integer phases is found using a procedure developed to solve for magnetometer biases. In addition to a ...
متن کاملSingle-Epoch Integer Ambiguity Resolution with GPS-GLONASS L1-L2 Data
The effectiveness of single-epoch integer ambiguity resolution, which provides centimeter-level relative positioning in real-time, is a function of the number, quality and type of carrier phase measurements available. We apply the Local-Minima Search (LMS) method epoch-by-epoch to GPS-GLONASS dual frequency carrier phase measurements taken over 2, 9 and 18 km baselines. While the application of...
متن کاملGPS/GLONASS System Bias Estimation and Application in GPS/GLONASS Combined Positioning
Multi-GNSS data analysis has become a new challenge with the development of satellite navigation systems. System bias is the key issue in Multi-GNSS data analysis, which has no recommended models within IGS community. We introduce the integrated data analysis model developed at the GNSS data analysis center of Shanghai Astronomical Observatory (SHAO). Based on the routine GNSS data analysis at ...
