The GS11 is a multi-constellation GNSS smart antenna with visual surveying built in. Its dual cameras, integrated Class 3R green laser and calibration-free tilt compensation give three ways to reach a point: pole it, tilt it, or shoot it from the imagery. Paired with Leica X-PAD, the cameras become workflows rather than pictures. Visual stakeout overlays navigation guidance on live site imagery, AR visual survey overlays captured data on the live stream, and image groups let the surveyor create points where the pole tip cannot safely go. Leica quotes image points at typically 5 mm + 2 mm/m up to 10 m, and laser points at typically 10 mm + 5 mm/m up to 25 m. Underneath it is a serious receiver: 1400+ channels, 8 mm + 1 ppm RTK, dual hot-swappable batteries for a 12 hour day, and 4G LTE with UHF for base-to-rover work. Two configurations: the GS11 T for conventional GNSS surveying with tilt compensation, and the GS11 I with imaging and laser.
