利用非气象参数对流层延迟估计模型加速PPP收敛

Using Non-meteorological Parameters Tropospheric Delay Estimation Model for Accelerating Convergence of PPP

基于非气象参数的对流层延迟估计建模的研究日趋成熟,其应用范围也不断拓宽。主要研究了其在精密单点定位中的应用,从定位精度和收敛时间两个方面分析了其应用效果。经过实验验证,在应用了非气象参数估计模型以后,定位的收敛时间得到显著改善,加快了约23%,同时其对定位精度的影响不显著。

Research based on non-meteorological parameters in the tropospheric zenith total delay estimation model is becoming mature and the scope of applications continues to broaden. We studied application of non-meteorological parameters to precise point positioning, and analyzed the effect of its application from the aspects of positioning accuracy and convergence time. Experimental results show that, when applied the non-meteorological parameter estimation model, positioning convergence time has been significantly improved by approximately 23%. However, there was no significant change in positioning accuracy.
