Abstract
Official abstract text for this publication.
A micro-electro-mechanical systems (MEMS) inertial measurement system facilitates accurate location and/or attitude measurements via passive thermal management of MEMS inertial sensors. Accuracy of the system is also improved by subjecting the inertial sensors to programmed single-axis gimbal motion, and by performing coarse and fine adjustments to the attitude estimates obtained by the system based on the programmed motion and on the passive thermal management of the sensors.
First claim
Opening claim text (preview).
What is claimed is: 1. An inertial-measurement system, comprising: a micro-electro-mechanical systems (MEMS) inertial sensor having a sensor contact and being constructed to provide an indication of motion; a circuit board comprising circuitry constructed to receive the indication of motion from the inertial sensor and generate a sensor signal based on the indication of motion, the circuit board disposed in proximity to the inertial sensor without being in direct physical contac…
