The development of Precise Point Positioning (PPP) made the Bandung Institute of Technology make PPP processing software. The software is called ITB-RTKPPP (Institut Teknologi Bandung-Real Time Kinematic Precise Point Positioning). The parameters of the ITB-RTKPPP results to be researched are position and Zenith Tropospheric Delay (ZTD). ITB-RTKPPP was created at the end of 2021, so validation is needed to check the advisability of the software. In processing ITB-RTKPPP, there are several input data such as satellite time correction data (clk) and orbital & satellite time correction data (sp3) which will be checked regarding the effect of using the two data. ITB-RTKPPP data processing in this research was carried out using four different schemes, namely scheme 1 using clk data and final sp3 data, scheme 2 not using clk data and using final sp3 data, scheme 3 using clk data and sp3 rapid data, and scheme 4 does not use clk data and uses sp3 rapid data. The purpose of this research was to test the validation in terms of position and ZTD and the effect of using clk data and sp3 data on the accuracy of ITB-RTKPPP processing. The test is done by calculating the RMSE (Root Mean Square Errors) and correlation coefficient value. The result of calculating the RMSE value on the ZTD results is centimeter-level, such as scheme 1 is 2.61 cm, scheme 2 is 6.73 cm, scheme 3 is 2.76 cm, and scheme 4 is 6.94 cm. A reasonable accuracy of PPP observations is centimeter-level. It can be concluded that the ITB-RTKPPP software can be used as PPP processing software to obtain the ZTD value. On the other hand, the position value results are still bad, so improvements are needed in the processing algorithm. While the use of clk data and sp3 data affects the level of processing accuracy, as seen from the different RMSE values.
