What is tilt compensation in GNSS receivers?
Category: survey
Tilt compensation allows GNSS receivers like EMLID RS4 to measure accurate positions WITHOUT holding the pole perfectly vertical. Traditional surveying requires bubble-leveling the pole—time-consuming and impossible in some terrain. With IMU-based tilt compensation (Emlid publishes RTK + 2 mm + 0.3 mm per degree of tilt on the RS4), you can work with the pole tilted and still get centimetre accuracy. This saves time across a survey day and enables measurement in tight spaces, under obstacles, and on steep slopes. RS4's 672 channels combined with tilt comp makes it our go-to for GCP collection.
