More Information
Summary:The invention relates to a satellite timing method based on wide area differential reinforcement, which is technically characterized in that each difference station carries out pseudo-range observation of a code phase and a carrier phase, and a main difference station and a satellite navigation system have synchronous time and can both measure a position of a code phase observation value and a carrier phase observation value of a pseudo range. The invention has the main effects of enhancing the accuracy of satellite navigation, and utilizing the method to cause the satellite navigation to achieve 1 nsec to 3 nsec and secondly, simplifying the configuration of a ground monitor system, and lowering the construction cost of a difference network.
