METHOD OF ESTIMATING ERRORS AND CONTROLLING RAW INFORMATION SENSORS IN GIMBALLESS INERTIAL NAVIGATION SYSTEM IN GROUND CONDITIONS AND APPARATUS THEREFOR

摘要

FIELD: physics, navigation.;SUBSTANCE: invention relates to instrument-making and can be used in processes for controlling raw information sensors in a gimballess inertial navigation system (GINS) in ground conditions. Error estimation and control of raw information sensors in a GINS is carried out by mounting the GINS on a platform with a base and carrying out initial alignment of the GINS, followed by conversion thereof to self-contained operating mode. In said mode, the GINS is successively turned by certain banking and pitch angles, followed by pre-start check of errors of the GINS. The apparatus for implementing the method consists of a base 1 on which a platform 2 is placed for mounting the GINS to be inspected. The base 1 is in the form of a rotating frame, the rotational axis 5 of which is perpendicular to the rotational axis 7 of the rotating platform 2. On the rotational axes 5 and 7 of the base 1 and the platform 2, there are drives for setting the banking and pitch angles of the inspected GINS.;EFFECT: increased reliability.;2 cl, 1 dwg
