From the OP's article-First stanza:
"...the Pole-21 anti-missile jamming device..."
Further down:
"...Russia will be virtually impenetrable to missiles using satellite navigation."
- jalk 10y agowouldn't it more be like: missiles will not hit the designated target, but something near by
- dtparr 10y agoShouldn't that really be using only satellite navigation? Anything with a backup (e.g. inertial, celestial, terrestrial) should still be viable, though perhaps degraded in accuracy. But hardly impenetrable.
- TeMPOraL 10y agoI wonder about it too. From what I read, military-grade inertial navigation is pretty damn accurate.
- 24gttghh 10y agoOnboard precise clock, very accurate ground/airspeed gauges, heading tracking would get you pretty close. Maybe not laser-guided close, but hey what are cluster-bombs for?
- arpa 10y agoor nuclear warheads.
- woodman 10y agoThe terrain following guidance in cruise missiles had an accuracy of a few meters in the early 80s. The only place that tech doesn't work is over the ocean... where there aren't any Russian cell towers. http://www.dtic.mil/dtic/tr/fulltext/u2/a110286.pdf http://www.dtic.mil/dtic/tr/fulltext/u2/a110286.pdf
- 24gttghh 10y agoRight. This would specifically inhibit things like GPS guided cruise missiles, not laser-guided or maybe even radar-guided munitions.
- varjag 10y agoNone of American missiles and smart munitions uses GPS as a sole guidance method. Those that do use it as an enhancer to the primary inertial system.
- lallysingh 10y agoYeah but all the backup stuff is still expensive to develop/build with good quality. I can buy a good GPS for a few hundred bucks. I don't think this is to defend against American missiles.
- openasocket 10y agoCelestial Nagivation? Do you mean missles can navigate by, like, finding the North Star? Are there cameras mounted on the sides that can track stars? That is fascinating!
- dtparr 10y agoNot just the North Star, of course, but yeah, they know where certain stars should be and compare what they see. The Trident Missile (sub launched missile) uses it in conjunction with inertial nav to correct its course mid-flight.
- TeMPOraL 10y agoYes, and the article I linked names "GPS, GLONASS, Galileo and Beidou" directly. That's what I consider stating something explicitly :).
- 24gttghh 10y agoFair enough :)
- PerfectDlite 10y ago> Russia will be virtually impenetrable to missiles using satellite navigation Wow, that's one wishful thinking, especially considering lame attempt to disrupt them when missiles basically already approached their target.
