ALERT! If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

Make sure there are "P1 or C1, L1, P2, L2" observations in your rinex file before processing it with PPP applications. Some times you have to use C1 instead P1, then you add "useC1 = TRUE" to enable this option.

Please check you observation file, there are no 'P1' observations in your rinex file though 'P1' indeed exist in the header, so you should add "useC1 = TRUE" to COCO section in your configuration file.

Good luck with GPSTk!
