LiteSurvey Pro: Professional GNSS Surveying on iPhone and iPad LiteSurvey Pro is a field data collection app designed for use with compatible LiteSurvey GNSS receivers. It combines real-time RTK positioning, map-based GIS data capture, advanced measurement tools, and project management in a clean, modern interface optimized for iPhone and iPad. KEY FEATURES RTK GNSS POSITIONING Connect a compatible LiteSurvey GNSS receiver through supported MFi connectivity. Configure NTRIP correction services, monitor positioning solution and correction status, and support centimeter-level RTK workflows under suitable conditions. Accuracy depends on receiver hardware, correction data, satellite visibility, and the operating environment. MAP-BASED DATA COLLECTION Create and edit points, polylines, and polygons. Organize work in layers and use customizable attributes, notes, and photo attachments to build structured field datasets. ADVANCED MEASUREMENT On supported receiver models, use tilt compensation and laser ranging to capture points efficiently, including targets that are difficult to reach. Availability depends on the connected receiver and its capabilities. AR-ASSISTED PHOTO MEASUREMENT On compatible LiDAR-equipped iPhone or iPad models, connect a supported LiteSurvey GNSS receiver and use the required mounting hardware to perform AR-assisted photo measurements. Availability depends on the Apple device, receiver model, and accessories. COORDINATE SYSTEMS Use broad EPSG-based coordinate-system and transformation support for field projects, including supported geoid models, coordinate display formats, and measurement units. RECORDING AND EXPORT Export layer data as CSV and recorded tracks as GPX or KML. Record RTCM3 data and convert supported recordings to RINEX observation and navigation files for post-processing workflows. PROJECT MANAGEMENT Manage projects, layers, attributes, photos, tracks, and receiver files. Review collected features and share or export selected data when needed. HARDWARE AND COMPATIBILITY Some functions require a compatible LiteSurvey GNSS receiver, supported receiver capabilities, a LiDAR-equipped Apple device, or a dedicated mount. Feature availability varies by device and hardware. LiteSurvey Pro helps field professionals collect and manage precise GNSS and GIS data with a streamlined iPhone and iPad workflow.
