SATELLITE NAVIGATION SYSTEM OF THE WINGED ROCKET (OPTIONS) Russian patent published in 2018 - IPC H01Q1/28 

FIELD: navigation; antenna technology.

SUBSTANCE: invention relates to the field of anti-jamming satellite navigation systems proposed for use in cruise missiles. Satellite navigation system for a cruise missile (CM) contains satellite navigation equipment and an antenna system. Antenna system is made noise-proof in the form of an information processing unit and an antenna, which is made as separate antenna elements for receiving satellite signals. Each antenna element is connected to the information processing unit by an independent cable. Antenna is placed in the front end part of the CD along the circumference of the case under the radio-transparent fairing of the nose part of the KR, and the information processing unit is located in the compartment of the on-board equipment. Satellite navigation system of the supersonic cruise missile (CM), together with the main antenna system, may contain an additional antenna system. Such systems are designed to be jam-protected in the form of information processing units and antennas, each of which consists of antenna elements connected to the information processing unit corresponding to the main or additional antenna by an independent cable. Antenna of the main antenna system is located in the upper part of the CM under the radio-transparent fairing, and the antenna of the additional antenna system is located in the front end part of the CM along the circumference of the case under the radio-transparent cone of the CM. Data processing units are located in the on-board equipment compartment.

EFFECT: usage of the proposed solution makes it possible to provide high noise immunity, high accuracy, continuity of operation of cruise missile systems with significant cost savings, and also eliminates the need for additional hull calculations and costly tests related to the introduction of changes in the housing of the CM.
