Real-Time Kinematic (RTK) Precision
Centimeter-level geodetic positioning achieved through high-precision dual-frequency RTK GNSS modules paired with the Flemish FLEPOS Virtual Reference Station network.
FLEPOS Virtual Reference Network
Our aircraft maintain continuous 4G/LTE cellular NTRIP connection with FLEPOS, the official permanent GNSS reference network of the Flemish Government, yielding real-time centimeter positioning at each shutter release.
NTRIP VRS StreamQuad-Constellation Tracking
Simultaneous multi-band tracking of GPS (USA), GLONASS (Russia), Galileo (European Union), and BeiDou (China) ensures continuous satellite visibility and fixed integer ambiguity resolution even in challenging environments.
GPS+GLO+GAL+BDSGround Control Points (GCPs)
To provide an independent audit trail, calibrated terrestrial checkerboard Ground Control Points and Checkpoints (CPs) are surveyed on site. This validates absolute accuracy and produces formal ASPRS survey reports.

Standard consumer drone GPS suffers from 2 to 5 meter drift. Dronesnap RTK reduces absolute positional error down to under 2 centimeters. This eliminates warping, allows direct overlay onto municipal cadastral boundaries, and provides legally defensible site documentation.
