Method of calibrating inertial sensors |
摘要 |
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. |

1. A method of calibrating inertial sensors of working equipment, the method including:
capturing data from one or more inertial sensors and one or more temperature sensors located proximate the inertial sensors while the working equipment is not in operation; and updating a thermal bias error model for the inertial sensors with the data captured ‘from the inertial sensors and the temperature sensors, wherein a sensor subsystem having the inertial sensors and the temperature sensors is periodically powered up to capture the data while the working equipment is not in operation. |
