Carlson SurveyGNSS

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

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

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.

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.

Current version 3 available.

• Achieve high accuracy results in areas with limited or no real-time corrections
• Process static, “stop & go”, etc raw data
• Optimized for processing data from all 4 constellations (GPS, Glonass, Galileo, BeiDou) from capable GNSS receivers such as the Carlson BRx7
• Import GNSS observations from any GNSS receiver in RINEX format
• 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

• Accepts proprietary raw GNSS observations in the following formats: Rinex, Carlson, Hemisphere, uBlox, Trimble, Topcon
• Provides a straightforward, workflow-oriented UI including an overview map, observation files, computed vectors, and positions presented in a functional spreadsheet-like grid format
