METHOD OF INTEGRATING NAVIGATION INFORMATION OF STRAPDOWN INERTIAL NAVIGATION SYSTEMS WITH PRIORITY SELECTION SYSTEM Russian patent published in 2024 - IPC G01C21/18 G01C19/04 

FIELD: navigation systems.

SUBSTANCE: invention relates to navigation-aerobatic systems combining several inertial navigation systems. Disclosed method of generating navigation information of strapdown inertial navigation systems (SINS) is that by means of information on location, speed, orientation angles of object, coming from SINS, forming difference of measurements, which determines SINS operation mode, and then the obtained difference is transmitted to the unit of the priority mode of operation, in which the state vector of each of the operation modes is supplemented with information on the external state, which affects the quality of operation. At that, the operating modes state vectors are compared to each other by the majority criterion, after which the information of those correcting devices is rejected, readings of which have maximum deviation from the rest. Obtained data are then transmitted to the input of the correction generating unit, which forms a criterion for selecting the difference in input values between the SINS and the rest of the correcting devices. Obtained values form a feedback for correction of values readings.

EFFECT: high accuracy of determining coordinates and orientation angles.
