Precise Point Positioning Based on the RTKLIB and the Analysis of Result

 Based on the existing framework of RTKLIB, we analyze the main error model in precise point positioning and complete the precise point positioning solution by calling the error correction model algorithm. The analysis of positioning error shows that the error in three directions of X,Y and Z is 01 meters in 80 epochs, and gradually decreases to stabilize. The positioning error is 7 cm at 180 epochs..
