| Abstract: | The mathematic model of GPS dual-frequency precise point positioning and the corresponding program named "GPS-PPP" recently developed by the author were presented.A group of tests using different dynamic data were carried out,including static test,simulated dynamic test using static data and airborne dynamic test,besides,an extensive validation of accuracy was evaluated.The experiments demonstrate an accuracy of a few centimeters for a whole day static solutions and several centimeters to a few decimeters f... |
