Analysis of Tropospheric Correction Models in Navigation Satellite System

Abstract:

In order to obtain high-precision navigation satellite system time, the errors of navigation satellite system signal need to be calibrated during its transmission, among which, troposphere delay is one of the major errors of navigation satellite system precision positioning. The calibration of troposphere delay has been compared and studied on the basis of model function theory. The troposphere models described include Marini model, Hopfield model, Saastamoinen model, Black model, and the impact extent of meteorological parameters like temperature, pressure, humidity and geographic information of observation station have been analysed quantitatively, which have been systematically analysed the characteristic of troposphere delay and the accuracy of error calibration model. Moreover, by using the data collected by IGS tracking stations to validate the analysis results of models, which has shown that Black model is better than other models when it comes to the extent of meteorological influence and also superior to the troposphere delay generated by the internal calibration model in GPS receiver.
