[0019] The fast-recovery type-in-motion-in-motion aligning method related to the invention solves the problems of the fast-moving base alignment of the inertial navigation system and the fast response and closed-loop scanning of the control system in a dynamic environment.
[0020] like figure 1 As shown in the figure, the fast-recovery type on-the-fly satellite alignment method involved in the present invention, by introducing high-precision GPS information, uses GPS position, speed and other information as the reference quantity of the inertial navigation system, and performs information fusion with the inertial navigation system Solution: On the basis of the original static alignment and dynamic tracking, the dynamic base alignment technology is added, that is, when the vehicle is in motion, the azimuth angle of the vehicle relative to the true north direction can be calculated through the comprehensive calculation of sensors such as gyroscope and accelerometer. and attitud...
