Carlson SurveyGNSS v3

Carlson SurveyGNSS post-processing software is a reliable and precise tool for raw GNSS post-processing applications and tightly integrated into the Carlson office and data collection workflow

The module was designed specifically for land surveyors and GNSS positioning professionals looking to achieve sub centimeter accuracy and provide quality assurance 

Carlson SurveyGNSS supports Precise Point Positioning (PPP) as a separate module. Raw data from any single or dual frequency phase data receiver can be used for PPP processing. There is no need for a base or reference network; the receiver can log data autonomously. Depending on observation time, centimeter-accuracy is achievable

Carlson SurveyGNSS uses locally available positions and associated observations to compute GNSS Resections and Virtual Reference Stations. The Virtual Reference Station is created as a RINEX file. The VRS can be used as base in both static and stop and go surveys and available as a separate module add-on

Current version 3 available
