Abstract
A method of calibrating inertial sensors of working equipment, such as a vehicle or survey equipment, includes determining whether the working equipment is in operation or not. Data is captured from inertial sensors and associated temperature sensors while the working equipment is out of operation. The captured data is used to update a thermal bias error model for the inertial sensors.
