| Abstract: | PPP method used for ZPD (Zenith Path Delay) estimation is discussed. The ZPD of seven IGS tracking stations are calculated using the software TriP designed by Wuhan University.The results are compared with the ZPD data provided by the IGS Analysis Centers.The analysis demonstrate that the accuracy of PPP based tropospheric delay estimation can achieve about 4 mm. |
