| Abstract: | Based on the GPS observations and site specific pressure observations of the Hong Kong satellite positioning reference station, the effect of pressure parameters on estimation of ZTD and ZHD were analyzed. The result shown, in the practical operation of the GPS/MET, the estimate of the ZTD parameters are less depended on the accuracy of the pressure, you can even use the GPT model to get these pressure parameters. However, when estimating the ZHD, it is required to use the pressure observations in high accuracy. For those stations that the GPS receiver and the pressure sensor are not located in the same position, the correction due to the height should be made. |
