Pocket-Sized Laser IMU-RTK GNSS Receiver

A compact, high-performance GNSS solution for daily land surveying. Featuring a 1408-channel GNSS module, advanced IMU, integrated dual cameras, and laser rangefinder, it delivers reliable positioning in challenging environments, even under high solar activity.

    • Integrated high-precision green laser enables accurate 3D point capture without physical access, delivering 2 cm accuracy at 5 m and 3 cm accuracy at 10 m for safe remote measurements.

    • 1408-channel multi-constellation GNSS with iStar 2.0 provides consistent RTK performance and high fix reliability even under dense foliage or near structures.

    • 200 Hz calibration-free AUTO-IMU supports tilt-compensated measurements up to 60°, maintaining approximately 3 cm accuracy and reducing field time by up to 30%.

    • Visual navigation and AR stakeout with dual cameras and VPT virtual pole tip technology improve targeting accuracy and accelerate stakeout workflows.

    • Survey-grade accuracy with RTK performance of 8 mm + 1 ppm horizontal and 15 mm + 1 ppm vertical, PPK accuracy of 3 mm + 1 ppm horizontal and 5 mm + 1 ppm vertical, and high-precision static down to 2.5 mm + 0.1 ppm.

    • Rugged IP68-rated design with metal chassis, operating from −40°C to +65°C, weighing only 800 g, and offering up to 20 hours of RTK rover operation or up to 15 hours of laser survey use.
