The Integration of GPS and Interferometric Quantum Position System for High Dynamic Precise Positioning

摘要：

In order to achieve high precision positioning with high reliability, the integration of GPS and interferometric Quantum Positioning System (QPS) is proposed. The integration of these two systems will provide a better Position Dilution of Precision (PDOP) and make the Double Difference Integral Ambiguity (DDIA) of GPS L1 carrier phase fix within a few epochs, thus it can improve the integrity and reliability of precise positioning. This can be for high dynamic user where the fixed DDIA should be determined in real time. Here we provide a possible way to integrate the two systems, where Household transformations and other orthogonal transformations are used to ensure our method to be numerically stable, Least-squares Ambiguity Decorrelation Adjustment (LAMBDA) or MLAMBDA algorithm is used to determine the fixed solution of DDIA efficiently. Our analysis results show a good prospect for this integration.
