EZSurv® Post-Processing software


With EZSurv® latest version, Effigis brings you centimeter accuracy at a single keystroke. Literally, simply import your survey or GIS raw data into EZSurv and let it do the work for you.

EZSurv automatically:
  • analyzes your data
  • selects and imports on your PC the closest base stations data for differential calculation
  • imports on your PC precise orbits and clocks for Precise Point Positioning (PPP)
  • supports most of the GNSS satellite constellations (GPS, GLONASS, Galileo and BeiDou/Compass)
  • can achieve millimeter/centimeter-level accuracy
  • ensures legit access to base station providers if required
  • manages time synchronization between your data and the reference data (base station and/or precise Orbits and Clocks)
  • instantly delivers corrected data

EZSurv version 2.92 also offers an enhanced, user-friendly Google Earth-based interface, which gives you access to detailed information about more than 8,000 base stations.

Supported Processing Mode

Differential (using base station data as a reference site):

  • Vector/baseline between static antennas
  • Trajectory from moving antennas
  • Kinematic/semi-kinematic from stop-and-go mode (supports initialization process for L1 receiver)

Precise Point Positioning (using precise orbits and clocks as a reference):

  • Static (several epochs generating one position)
  • Kinematic (moving antenna, stop-and-go)
