Abstract�� A method of correcting INAS error based on landmark-image messages is described, emulating results are presented. Using landmark-imaging system on the photoelectrical platform, the position of a plane can be worked out through landmark-image detecting, image transforming, matching orientation and coordinate transforming. Comparing this position with the coordinates received by INAS, the flight-path error of the plane can be calculated, accordingly the error of INAS can be corrected.
Keywords�� inertial navigation   errors   correction   integration   landmark image
