Abstract
A thermal regulation system includes an inertial measurement unit (IMU), one or more temperature adjusting devices in thermal communication with the IMU, and configured to adjust a temperature of the IMU from an initial temperature to a predetermined temperature, a filler provided in a space between the IMU and at least one temperature adjusting device of the one or more temperature adjusting devices, and a shared substrate configured to bear a weight of the IMU and the one or more temperature adjusting devices. The shared substrate includes a metallic board.
Claims20
A thermal regulation system comprising:
- an inertial measurement unit (IMU);
- one or more temperature adjusting devices in thermal communication with the IMU, and configured to adjust a temperature of the IMU from an initial temperature to a predetermined temperature;
- and
- a shared substrate configured to bear a weight of the IMU and the one or more temperature adjusting devices, the shared substrate including a metallic board, and the IMU and the one or more temperature adjusting devices being disposed on a same surface of the shared substrate.
A method of regulating a temperature of an inertial measurement unit (IMU), comprising:
- sensing an initial temperature of the IMU with a temperature sensor;
- providing a thermal stimulus from one or more temperature adjusting devices to adjust a temperature of the IMU from the initial temperature to a predetermined temperature, wherein a shared substrate is configured to bear a weight of the IMU and the one or more temperature adjusting devices, the shared substrate includes a metallic board, and the IMU and the one or more temperature adjusting devices are disposed on a same surface of the shared substrate;
- and
- adjusting a measurement provided by the IMU based on a known bias error of the IMU at the predetermined temperature, to reduce error.
A movable object comprising:
- an inertial measurement unit (IMU);
- one or more temperature adjusting devices in thermal communication with the IMU, and configured to adjust a temperature of the IMU from an initial temperature to a predetermined temperature;
- and
- a shared substrate configured to bear a weight of the IMU and the one or more temperature adjusting devices, and the IMU and the one or more temperature adjusting devices being disposed on a same surface of the shared substrate.
