viDoc RTK · iPad Pro
RTK antenna for mobile 3D data captureiPad Pro-compatible RTK antenna · PIX4DcatchviDoc RTK · iPad Pro synchronises with PIX4Dcatch to add real-time positioning to mobile images. Handheld data captured through Bluetooth and NTRIP connections can be used in georeferenced 3D modelling and survey workflows.

Combine mobile images with RTK positioning.
Mobile data capture
Connect a compatible device running PIX4Dcatch to viDoc via Bluetooth to combine image capture with position data.
Cloud evaluation
Upload captured data to PIX4Dcloud and measure lengths, areas and volumes on the processed model.
Field documentation
Create mobile 3D records of construction sites, bridges, concrete pours and underground infrastructure.

Device and antenna work together
viDoc is a mobile RTK solution designed by vigram GmbH. GNSS positions and PIX4Dcatch image records are used together; results can be shared with the team after processing.
