Abstract
Systems and methods for monitoring the tool rotation of a survey tool within a wellbore during a gyrocompassing survey measurement are provided. A plurality of signals from at least one accelerometer module of the survey tool is indicative of measurements of the Earth's gravitation vector taken by the at least one accelerometer module during the gyrocompassing survey measurement. The plurality of signals is used to calculate a tool face rate of change of the survey tool with respect to the wellbore during the gyrocompassing survey measurement.
