System with oven control and compensation for detecting motion and/or orientation

A system for improving accuracy in a motion or orientation sensing device, the system comprising:

• an isolation platform having a device mounting region and an isolation structure providing mechanical and electrical connections between the device and components not located on the device-mounting region;
• a heat source disposed on the isolation platform;
• a device disposed on the isolation platform;
• and
• at least one internal temperature sensor disposed in a local area on the isolation platform adjacent the device and configured to detect a temperature of the local area;
• at least one controller programmed to:
• receive internal temperature signals from the at least one internal temperature sensor indicating the temperature of the local area,
• receive signals indicating an ambient temperature of an ambient environment,
• control the heat source to achieve a desired temperature of the local area,
• receive signals from the device, and
• compensate the received signals from the device by a compensation factor that varies based on a combination of the temperature of the local area and the ambient temperature.
