Carlson SurveyGNSS

Overview of Carlson SurveyGNSS (GNSS global positioning solution)

Carlson SurveyGNSS post-processing software is a reliable and precise tool for all post-processing applications and is tightly integrated into the Carlson field and office workflow. For surveyors and positioning professionals looking to achieve centimeter accuracy when working on the edge of their RTK infrastructure, perform sub-centimeter positioning, and/or provide the highest quality assurance to their customers, SurveyGNSS is the solution.

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.

Features of Carlson SurveyGNSS

• Achieve high accuracy results in areas with limited or no real-time corrections
• Process static, kinematic and “stop & go” raw data
• Least squares adjustment including statistical testing
• Optimized for processing data from all 4 “major” constellations (GPS, Glonass, Galileo, BeiDou) from capable GNSS receivers such as the Carlson BRx7
• SurveyGNSS can also process data from the Indian Regional Navigation Satellite System (IRNSS)
• Import GNSS observations from any GNSS receiver in RINEX format
• Accept GNSS observations in a variety of proprietary formats
• An intuitive user interface with tables, maps and graphs
• Improve the quality of single frequency GIS data
• Interact efficiently with Carlson SurvCE, SurvPC and Carlson office software
• Do quality control of GNSS data before export to Survey or GIS software.

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.
