METHOD OF INCREASING NOISE IMMUNITY OF INTEGRATED ORIENTATION AND NAVIGATION SYSTEM Russian patent published in 2013 - IPC G01S5/02 

FIELD: radio engineering, communication.

SUBSTANCE: method of increasing noise immunity of an integrated orientation and navigation system mounted on a mobile object involves the mobile object receiving a navigation signal emitted by a satellite, retrieves satellite coordinate information therefrom; using signals from the satellite to spaced-out antennae, the angle β between the base of the spaced-out antennae and the direction of the satellite is calculated; coordinates of the mobile object are determined using a gimballess inertial navigation system; using information on coordinates of the satellite and coordinates of the mobile object, the angle β* between the base of the spaced-out antennae and the direction of the satellite is calculated; the difference between β and β* is calculated; if the difference is greater than an allowable error value, the received navigation signal emitted by the satellite is considered a noise signal and is excluded from further processing.

EFFECT: screening signals from different noise sources transmitted along with navigation signals received from an arbitrary number of navigation satellites.
