摘要:
An on-chip navigation system, optionally combined with GPS (Global Positioning System) and/or an imaging array, which incorporates MEMS (MicroElectroMechanical Systems) components is possible by the use of careful material selection and novel bonding techniques used during fabrication. The use of MEMS components permits many of the components of a typical inertial navigation system to reside on a single chip. Because the components are in close proximity, the components can then be used to monitor the environmental changes of the chip, such as temperature and vibration, and correct for the resulting offsets of other components. This allows improved system performance even if the individual sensor components are not ideal.
