| Abstract: | Universal Kriging technology with different semi-variation function model and its application in GPS height fitting field is briefly discussed. The performance of GPS height anomaly fitting in level terrain was studied using universal Kriging technology with four kind of semi-variation function models by illustration. Preliminary results show that universal Kriging technology can improve accuracy of GPS height nomaly fitting. Although four kind of semi-variation function models are obviously different, accuracy of GPS height anomaly fitting based on universal Kriging is same. |
