Application of a Rapid Integer Ambiguity Resolution Technique in High Accuracy GPS Positioning and Navigation

Global position system(GPS) carrier phase integer ambiguity resolution is the key issue and challenge for high accuracy positioning and navigation. The article analyzed the independent variable in the ambiguity search space and derived the new Transition Matrix that relates to all the measurement residual to the minimum ambiguity search space directly. The technique not only improves the calculation efficiency and ambiguity resolution time, but also improves the reliability. The search space is minimized by selecting only those combinations of possible ambiguity value which are consistent with the satellite geometry and the measurement residual. The experimental data results indicate that the proposed method is effective.
