SV1
GNSS receiver built for AR stakeout, with 1,408 channels and IP68 protection.
SmartViewer SV1 is designed around AR stakeout: cameras on the controller and beneath the receiver hand guidance over to each other as you approach a point. It tracks all constellations with the ZENITH algorithm, tilts up to 60° with EZtilt, and supports SPOS, STEC's PPP correction service delivered by L-band satellite, for remote sites where no base station or internet correction is available.

Main Capabilities

AR Stakeout
The controller shows the general direction from a distance, then switches to the camera beneath the receiver for precise guidance near the point.
SPOS
STEC Positioning Service delivers PPP corrections from L-band satellites, so one rover can reach high accuracy in deserts, mountains, jungles or at sea.
EZtilt
Collect points at any pose within 60° seconds after fixing, with no calibration or initialisation.

- ZENITH algorithm for fast fixing
