The impact of the choice of different mapping function and prior model on zenith delay
Yan Wang
One of the main influences of restricting GPS precise positioning is troposphere delay error currently, and it is also the hotspot and difficulty in present study. Therefore, it is very necessary to set up troposphere correction model suitable for a certain region. This paper is verified by experiments that the zenith delay error calculated by Project Function Dry:GMF+Wet:GMF is significantly smaller than it is in other models when it is in troposphere delay correction in the mid-latitude region, which shows that the model is more suitable for this region, correction is more precise, and the effect is more superior.
