Abstract

PROBLEM: Leveling over a wide range of tilt angles with high accuracy conventionally involves the use of two tilt sensors: one low-accuracy broad-range sensor for coarse levelling, and a high-accuracy narrow-range sensor for fine levelling. The use of two sensors with different accuracies and ranges renders the levelling mechanism unnecessarily costly. SOLUTION: Two-stage automatic leveling method and device using a single narrow-range high-accuracy inclinometer mounted on a motorized self-leveling tribrach platform. The inclinometer is assumed not to provide any reliable inclination information outside of its measurement range. The first, auxiliary or coarse leveling stage entails systematically trying out different platform orientations (following a pitch-roll curve) until the platform is oriented such that its inclination falls within the measurement range of the inclinometer. The second, main leveling stage entails fine levelling, based on the angle readings from the inclinometer.
