Assuming you have created a valid RINEX observation file from your raw GPS observation data, five simple steps are all that is needed to use PPP.

• Step 1
  Using the browse button, select the RINEX observation file (insert link to 1.2.2) you wish to process;
• Step 2
  Select the mode of processing required: static for a "fixed" GPS receiver or kinematic for a "moving" GPS receiver;
• Step 3
  Select the Reference Frame for output positions: NAD83(CSRS) or ITRF;
• Step 4
  Press the submit button;
• Step 5
  Once processing has successfully completed, select from the "Results Download" box the processing output files you wish to retrieve. PPP results should be verified to ensure their validity (insert link to 1.4).
