Abstract

As the main part of INS (inertial navigation system),accelerometer is used to measure the linear acceleration of the vehicle.The position is obtained after double integrals.In order to locate the vehicle accurately,the error of inertial sensors should be appropriately corrected.Based on static test and analysis of the selected accelerometer ADXL105,the error correction model of ADXL105 used for vehicle positioning is built and proved to be efficient.
