METHOD FOR AUTONOMOUS ORIENTATION OF OBJECTS IN NEAR-EARTH SPACE Russian patent published in 2023 - IPC G01C23/00 G01C21/16 G01S5/02 

FIELD: moving objects strapdown autonomous orientation.

SUBSTANCE: invention relates to a method for strapdown autonomous orientation of moving objects in near-Earth space. For the orientation of moving objects, primary instrument information is formed about the apparent acceleration vector and the vector of the resulting magnetic field according to the signals of pre-calibrated triaxial blocks of accelerometers and magnetometers, as well as on the subsequent processing of this information, taking into account the use of navigation information received from a satellite navigation system, correct taking into account the results of previously performed technological calibrations, they are brought to the axes of the orthonormal basis m=XYZ associated with the object then, based on the use of navigation information from the satellite navigation system, the components of the vectors of the Earth's gravity field of the geomagnetic field and the apparent acceleration reduced to the axes of the basis are calculated q, and finally, the vectors corrected and reduced to the bases m and q are used to determine the orientation parameters of the object using non-integral strapdown processing algorithms vector information.

EFFECT: increased accuracy of solving problems of orientation of moving objects.
