PLATFORMLESS INERTIAL ATTITUDE-AND-HEADING REFERENCE Russian patent published in 2015 - IPC G01C21/16 

FIELD: measurement equipment.

SUBSTANCE: device comprises a three-component block of sensors of angular speeds, a three-component block of sensors of linear accelerations, a course corrector, a computing unit, an unit to form a matrix of guiding cosines, an integrating unit, the Kalman filter and an unit of measurement functions generation connected to each other in an appropriate manner. The design of the device provides for an adaptive (pendulum) correction of a platformless inertial navigation system, realised by means of the Kalman filter, in which the amplification ratio varies with an account of current values of overload modules and angular speeds in the unit of measurement functions generation. At the same time they may use the sensors of angular speed and the sensors of linear acceleration of medium and low accuracy, also of a micromechanical type.

EFFECT: expansion of functional capabilities.
