Product dossier

Emlid Reach RS3

Accurate results even with large tilt angles

Tilt compensation

  • Large tilt angles:

    Measure with up to 60° of tilt while staying within 20 mm of accuracy, corrected in real time.

  • Magnetic immunity:

    IMU sensors give robust tilt compensation even when working close to metal structures.

  • Quick initialisation:

    Tilt initialisation takes about 20 metres of walking or 10–20 seconds of tilting.

  • Calibration-free:

    Each IMU is calibrated at the factory, so the RS3 is ready to use out of the box.
