METHOD FOR CORRECTING STRAPDOWN INERTIAL NAVIGATION SYSTEM OF UNMANNED AERIAL VEHICLE OF SHORT RANGE USING INTELLIGENT SYSTEM OF GEOSPATIAL INFORMATION Russian patent published in 2020 - IPC B64C19/02 B64C13/00 G05D1/00 G01C23/00 

FIELD: aviation.

SUBSTANCE: invention relates to an unmanned aerial vehicle (UAV) positioning method in off-line state. For this purpose, current coordinates of information-measuring devices are continuously determined by low-precision strapdown inertial navigation system (SINS) of UAV. Periodical correction of current position based on signals of satellite navigation (SSN) is performed. Validation of SSN data is performed. In automatic mode, regions or objects of observation are fixed based on information of optoelectronic system. Corrections for current coordinates of the latter are generated. At the pre-start preparation stage, the period of forming the data areas of the strap-down inertial system is calculated. In flight, processing, geo-spatial referencing and storing images on UAV are stored.

EFFECT: higher accuracy of drone positioning in autonomous mode.
