US technology thwarts Russian jammers that have diverted JADAMS
2007-07-14
From Geostrategy-Direct, subscription.
PARIS — Boeing has completed flight testing of an anti-jamming system for a key airborne weapon sought by Middle East clients.

The U.S. defense major has concluded flight testing of its Integrated GPS Anti-Jam System for the Joint Direct Attack Munition. JDAM, which transforms general-purpose air bombs into smart weapons, has been supplied to Israel and sought by Egypt and Saudi Arabia.
Who would get the technology and give it to all their friends.
"IGAS uses digital signal processing to significantly reduce the impact of GPS jamming, allowing the warfighter to use JDAM with confidence in a variety of battlefield environments," Boeing IGAS program manager Dennis Kast said. "Its performance continues to exceed our highest expectations."

Over the last two years, pilots have reported that JDAM's performance was affected by Russian-designed jammers. In some cases, the weapon veered sharply from its planned course and toward civilian sites.
Pooty-Poot. Look into his soul and you will see that he is our friend™.
Executives said Boeing plans to complete IGAS development in 2007. They said deliveries to the U.S. Air Force would begin in 2008 for operations in Afghanistan and Iraq.
And in Iran....hey, I can dream, can't I?
JDAM is a GPS-aided guidance kit capable of guiding 500- to 2,000-pound warheads. The kit can be employed on a range of aircraft, including the F-15 and F-16.

#6  Home on jam is fine even if the jammer is offset. I'm sure the Russians aren't donating the jammers for free. There will be a limited supply. JDAM technology has eliminated the necessity for carpet bombing so we have plenty in the tank.

#5  back in the drive to capture baghdad during the highly mis-labled 'shock and awe' campaign we destroyed all the deployed soviet gps jammers using jdam munitions. rummy had a press conference to poit out the irony that the jammers were destroyed with the technology they were trying to inhibit.

#4  Some of weapons do have a Home On Jam ability (this is public information, not classified), though I don't know if JDAM does (it's made by Brand X). The value of a HOJ mode depends on the target. If it's an airplane or ship, then hitting the jammer is just as good. If it's a ground target, it depends. If you put the jammer right on the building (or whatever), then I call it a Homing Beacon. But, if you put it a few hundred yards away, killing it won't kill the target.

Of course, if you're willing to expend enough ammunition, you simply hit the jammers first, then drop the big ones unmolested. Kind of a Wild Weasel approach. HARM would do this, but it's a bloody expensive weapon to take out a little transmitter.

If you use a nuclear weapon, then there is no problem with jammers. [wag]

#3  OK, then - back to the big dumb BLU bombs for the Iranians

#2  The jammers themselves are probably small, unmanned and fairly cheap. They also surround lots of the Iranian nuclear facilities.

#1  "veered sharply from its planned course and toward civilian sites"

I wonder if they can make a JDAM kit that diverts and homes in on the jammers? Of course, blowing up mosques is not very good PR.
