There are various methods to process the kinematic GNSS data

  • local processing / on-line processing
  • dual differences / PPP

Most of our dual difference processing calculations are made with the old but good PNAV software. As PNAV requires data at the Ashtech format BES, this requires a difficult part of preprocessing of the data!

For the PPP processing we use locally GIPSY version 6.4 and GIPSY-X

There are also various good on-line PPP processors, see this page
