A method for determining and compensating for the scale factor error caused by change in the wavelength in a gps - supported into the - system

摘要

A method for determining and compensating for the by wavelength change in the case of a fed from a common light source fiber-optic gyroscope (fiber optic gyroscope) scale factor error caused in a gps - which are supported with kalman - correcting filter finished inertial course - and position reference system, characterized in that the for an axis with a comparatively high as a scale factor error correction - kalman filter correction value for the scale factor - error correction to a lower kinetic dynamics with is used, wherein the error correction is carried out with a time constant, which is large in comparison with a short time to be expected, which can be compensated not modulatable or sources of error.
