Reach RS3
RTK GNSS receiver with tilt compensation
Works as a base or rover with dual-band radio or NTRIP. Survey grade accuracy in RTK, PPK and PPP.
Centimetre accuracy up to 60° tilt
Reach RS3's IMU-based tilt compensation allows you to measure up to 60 degrees of tilt with an accuracy of 20mm.
Reach RS3 continuously measures and corrects tilt in real time to keep you on target.
Survey and stakeout faster. No need to check the bubble
Effortless and robust
IMU tilt compensation
Calibration-free
We calibrate each unit individually at the factory, so you can get your Reach RS3 up and running right out of the box.
Immune to magnetic disturbances
Unaffected by magnetic fields, the RS3 provides robust tilt compensation even when working close to metal structures.
Quick initialization
Tilt initialization takes about 20 meters of walking or 10-20 seconds of tilting. Usually ready on the way from the car.
Rapid and Reliable GNSS receiver
Gets a fix in 5 seconds
Reach RS3 gets a centimeter-accurate solution in about 5 seconds. It maintains robust performance even when the sky view is partially obstructed, or the receiver itself is tilted.
