Carlson SurveyGNSS is a specialized software solution for post-processing GNSS (Global Navigation Satellite System) data. It is designed for land surveyors and positioning professionals to achieve sub-centimeter accuracy in environments where real-time corrections are limited or unavailable. The software supports a wide range of GNSS receiver formats, processes static, kinematic, and “stop & go” data, and is tightly integrated with Carlson’s field and office workflows. It includes advanced baseline processing, quality control tools, and seamless interoperability with other Carlson software, making it a comprehensive tool for high-precision geospatial data handling.
