Realization and Precision Analysis of Single-Frequency Precise Point Positioning Software

  • An optimal mathematic model of single-frequency precise point positioning is built by using GPS carrier phase measurements and pseudoranges.Comprehensive error correction models are taken into consideration and a calculating module named TriP-SF is developed.An extensive validation of the accuracy in both static and kinematic modes are carried out,including simulation of dynamic trial using static data,carborne dynamic trial and airborne dynamic tests.The results demonstrate the accuracy about 0.2-0.3 m for the horizontal position components and 0.5 m for the vertical in the carborne and airborne experiment.In addition,locating precision varies from maneuverability.
