Abstract: Systems and methods are provided for calibrating and regulating the temperature of a sensor. One or more temperature adjusting devices can be provided to regulate the temperature of the sensor. One or more of the temperature adjusting devices can be provided to perform a calibration to determine a relationship between sensor bias and sensor temperature. The one or more temperature adjusting devices can be built into the sensor.

Abstract: A method for bus addressing includes receiving handshaking information from a component of a control system of an unmanned aerial vehicle (UAV), allocating a communication address to the component through a field bus, receiving a user instruction indicative of an index number of the component through a configuration interface, and establishing a correlation between a physical address of the component, the communication address, and the index number. The index number is configured to identify the component.

Abstract: An inertial measurement unit includes a sensor and a heat preservation system. The heat preservation system includes a heat preservation body and a heat source. The sensor is positioned on the heat preservation body. The heat source is configured to generate heat. The heat preservation body is configured to transfer the heat from the heat source to the sensor to maintain a preset temperature in a space surrounding the sensor.
