High-precision IMU - Tilt:RTK+2mm+0.3mm/°
Survey with under 20 mm precision at up to 60 degree tilt. Reach RS3 is calibration-free and works out of the box. The receiver is immune to magnetic disturbances, so metal objects and electronics don’t affect the accuracy.

Get a Fix in 5 seconds
The receiver gets a cm-accurate solution in ~5 seconds and maintains robust performance even when the sky is partially obstructed or the unit is tilted. Signals tracked: GPS/QZSS, GLONASS, BeiDou, and Galileo.

18 hours of work with tilt compensation
The industrial-grade battery can endure up to 22 hours of logging or 18 hours of work as an RTK rover with tilt compensation. For uninterrupted multi-day operations, simply connect a power bank via USB-C.
