Indigenous GNSS GLONASS may be used by the invention enemy together with foreign GNSS (such as GPS, Beidou, GALILEO, etc.) to improve management of troops and weapons, including the precision guided munitions. Therefore, GLONASS, as well as foreign GNSS, is the important jamming object in realizing of common reducing enemy’s combat capabilities strategy. On the other side, foreign GNSSs may be used commonly with GNSS GLONASS to solve similar problems in the Russian Federation Armed Forces. Therefore, friendly GNSS user’s navigational equipment is the important jamming protection object (including its protection from jamming signals created by friendly jammers). Known indigenous and foreign GNSS jammers are equally effective against enemy GNSS user’s navigational equipment and similar friendly equipment. In this article new way to reduce friendly GNSS user’s navigational equipment jamming effectiveness without reducing of similar enemy equipment jamming effectiveness is substantiated.
