Method for checking the inert measuring unit of vehicles, in particular of aircrafts, in the stationary state

摘要

The method involves calculating Euler angle changes and speed change within a given time period from the supplied data. Acceleration summation errors are determined by adding stored acceleration errors and the calculated speed changes by an acceleration sensor (10). Rotary rate-summation errors are determined by adding stored rotary rate errors and the calculated Euler angle changes by a rotary rate sensor (11). A testing is made whether the determined acceleration summation errors and the rotary rate-summation errors are within a preset tolerance range or not.
