摘要

A method for checking an inertial measurement unit of vehicles, in particular of aircraft, in the stationary state, wherein the inertial measurement unit (1) at least one acceleration sensor (10), which supplies a progressive acceleration signal, and at least one rotational speed sensor (11), which supplies a rate of rotation, wherein said interference potentials measuring unit (1) with a navigation computer - arrangement (2) is connected with at least one computer, which provides a first functional element (20), which is taken from the acceleration sensor (10) and translational acceleration signals supplied by the rotation rate sensor (11) receives as input data rate delivered and processed, which a second functional element (30), which the input data from the first functional element (20) receives and processes, and a third functional element (40), which the input data of the inertial measurement unit (1), from the first functional element (20) and the second functional element (30) receives and processes, is characterized by the steps of:a) providing data of the current position of the inertial measurement unit (1) and the current euler - angle as information on the current orientation of the inertial measurement unit (1) in the space;b) initialization of a strapdown - algorithm with the data provided in step a) of the current position, the current euler - angle and the current ..
