RESEARCH OF GPS ELEVATION FITTING MODELS BASED ON KRIGING METHOD
基于Kriging统计的GPS高程拟合方法研究

For solving the GPS elevation surveying problems in the local project,grounding on the principle of height translation as well as the traditional separate function model and statistical model of GPS height fitting,the model synthesized by moving surface model and polyhedral model for GPS elevation fitting based on Kriging method is presented.The GPS leveling experiment in certain area testifies to that this synthesized GPS elevation fitting model integrates the advantage of function model and statistical model,performs more perfectly in theory and improves the elevation precision distinctly in practice.
