Frequently Asked Questions
Can an RTK system maintain centimeter-level accuracy in challenging environments like forests or urban canyons?
RTK accuracy may degrade under GNSS signal obstruction. Using a full-constellation, multi-frequency receiver with IMU integration and multipath suppression can mitigate this. Technologies like hold-over and breakpoint-resume further enhance operational reliability.
In what formats can survey data be exported? Are GIS/CAD systems supported?
Export formats include CSV, DXF, Shapefile, KML, and more. Data can be transferred via Bluetooth or USB to software like ArcGIS, AutoCAD, and QGIS. Custom coordinate systems and field structures are supported for industry-specific workflows.
What are the main error sources in RTK surveying, and how can they be mitigated?
Errors mainly come from atmospheric delays, multipath, long base-to-rover distances, and signal blockages. To reduce these, survey in open areas, use receivers with multipath suppression and IMU support, and keep the base station within 30 km if possible.
Does the RTK system support importing or defining local coordinate systems?
Yes. The system allows importing user-defined 7/4-parameter transformations, datums, and custom local projections. It supports CGCS2000, WGS84, UTM, Lambert, and other national or regional standards for seamless GIS and engineering integration.
