Description

technical field

[0001] The invention relates to a low-cost, small-volume plate-type micro-inertial measurement system based on MEMS, which is used to provide the motion parameters (position, speed, attitude) of the measured carrier, and is suitable for micro-aircraft, automobiles, trains, etc., which require small volume and low weight. Lightweight, low-cost motion carrier for inertial measurement systems. Background technique

[0002] With the emergence of micro-inertial measurement devices such as MEMS-based micro-gyroscopes and micro-accelerometers, micro-inertial measurement systems have gradually penetrated into our lives. In daily life, the driver can identify his position and heading according to the micro-inertial measurement system to prevent getting lost; the vehicle control system can judge whether the vehicle is slipping and whether it needs to slow down according to the attitude and speed information provided by the inertial measurement system to ensure driving ...
