The Toknav T40 is a GNSS RTK rover receiver with 1408 channels covering GPS, GLONASS, BDS, Galileo, QZSS, SBAS and NavIC, delivering roughly 8mm+1ppm horizontal RTK accuracy. It adds a built-in laser rangefinder with dual-camera AR staking, letting an operator measure points up to about 30m away without standing on them, plus IMU-based tilt compensation. It runs on two hot-swappable batteries and has an IP68-rated magnesium-aluminum housing.
