Alpha G3X Visual RTK
Alpha G3X is a visual GNSS RTK receiver with a compact body (113 × 113 × 55 mm, 480 g) and a full feature set. It has 1408 channels and tracks GPS, BeiDou, GLONASS, Galileo, QZSS, SBAS and NavIC on all main frequencies.
Two cameras with low-distortion lenses enable AR stakeout: the app switches automatically from far-end to near-end AR about 5 m from the point (adjustable), with a clear 360° view even in strong sunlight and 1 cm accuracy. The calibration-free IMU needs no initialisation: after a few steps it enters inertial navigation, with up to 60° tilt at 2 cm accuracy.
The built-in 2 W radio covers the full 410–470 MHz band with the mainstream protocols, and its low-power LoRa mode reaches 8–12 km; an external radio can also be connected. IP67 protection, 1.8 m drop resistance and a 25.9 Wh battery make it field-ready, including as a drone base station or for PPP.
