METHOD OF COMPLEXING STRAPDOWN INERTIAL NAVIGATION SYSTEMS Russian patent published in 2017 - IPC G01C21/00 

FIELD: physics.

SUBSTANCE: several inertial navigation systems are described to form generalized output information about the location of the object, its orientation in space and its velocities, using external information to correct the systems included in the complex. To do this, output information coming from, at least, two strapdown inertial systems is compared by the majority sign, after which information of the strapdown inertial system that deviates most from the others is rejected, while according to the invention primary information in the form of the orientation matrices and the increments of the linear velocities arrives from the outputs of the strapdown inertial systems to the input of the primary information processing unit, in which, according to the given criterion, an averaged value of the orientation matrix and the increment of the linear velocities are formed, these averaged values are fed to the input of the navigation equation solving unit, and the output parameters obtained as a result of the solution of the navigation equations are fed to the input of the control unit in the form of the current coordinates and the object direction and its velocity, in which the output parameters of the strapdown inertial systems are compared with the output parameters of the navigation equation solving unit and the failure situations of the strapdown inertial system nodes are analysed.

EFFECT: increasing the accuracy of output information of the complex and the control depth of the systems that make up the complex.
