Abstract

Tropospheric delay is one of the important errors in positioning and timing. Lots of researches have been done, and many tropospheric correction models have been proposed. The precision of the models change with the location and meteorological conditions of the user. Significant improvements will been made within the precision of positioning and timing on researching tropospheric correction models. In this paper, the effects of different factors on the precision of tropospheric correction models are analyzed, and their proportions in the measurement uncertainty are elaborated. Based on the two years ZTD (zenith tropospheric delay) of BJFS station, the effects of meteorological parameters on the zenith delay correction are analyzed, and the precision of various models are compared. The result shows that the precision of models are the highest by using direct meteorological measurements, and the precision of ENGONS and UNB3 follow, and the models using reference atmospheric information get poor precision.
