METHOD OF DETECTING ERRORS WHEN DETERMINING ANGULAR SPATIAL POSITION USING MAGNETOMETRIC MEASUREMENTS Russian patent published in 2019 - IPC G01C17/00 

FIELD: physics.

SUBSTANCE: invention relates to the field of navigational instrument-making and can be used in systems of on-board radioelectronic equipment. For this purpose, the system comprises one or more data sources on angular spatial position, each of which is configured to generate a corresponding calculated solution from an angular spatial position; at least, one magnetometer made with possibility of magnetic field measurement; and at least one angular spatial position control device configured to use the corresponding calculated solution from the angular spatial position obtained from one or more data sources on the angular spatial position, for presentation of preliminary evaluation by measured magnetic field or preliminary estimation by model of Earth's magnetic field (MEMF) so that these estimates by measured magnetic field and MEMF were in common system of coordinates. At least one device for controlling angular spatial position is made with additional possibility of determining difference between preliminary evaluation by measured magnetic field and preliminary estimation by MEMF in common coordinate system. At least one device for controlling angular spatial position is made with additional possibility of issuing an emergency message that the corresponding calculated solution from the angular spatial position, used for presentation of preliminary evaluation by measured magnetic field or preliminary evaluation by MEMF, is false if difference between them exceeds specified threshold value.

EFFECT: technical result is higher accuracy.
