I am posting this in response to concerns raised in regards to the Russian-made GPS jammers the military recently came up against in Iraq. Hopefully, with will dispell some of the myths regarding how they work, how them ilitary works against them, and just how effective they are under ideal circumstances. First, a word on GPS. Since GPS went public, circa 1995, their have been two signal broadcasts. The original signal, broadcast at approximately 1500 MHz, which is now used for civilian localaization. So I will now refer to this as the Civilian signal. Finally, the bloc two (or L2)...

April 27, 2003: While Iraq's use of GPS jammers did not succeed in the recent war (the jammers were quickly located and bombed), three years earlier, one of Iraq's allies did make successful use of GPS jamming against U.S. and British troops. In the Summer of 2000, American, British and French tanks were competing for a $1.4 billion contract to equip the Greek army. For some reason, the GPS gear in the American and British tanks never seemed to work correctly during the tests. It was later discovered that the French had brought a small GPS jammer to the tank...

Attempts to jam U.S. GPS-based weapons and navigation systems in Iraq were a reminder of just how vulnerable the technology is. The space-based Global Positioning System (GPS) signal that guides smart bombs and cruise missiles to their targets underpins U.S. technological superiority on the battlefield. Yet because it is relatively easy to jam, it is also the Achilles' heel of U.S. military might. Although the integrity of the GPS signal was maintained in the war with Iraq, enemy attempts to corrupt it underscored the need to protect GPS-dependent weapons and navigation systems. Against a more capable enemy, GPS might find...

Rear Adm. John Stufflebeem meets with reporters on the Truman. It's a familiar duty. He was a Pentagon spokesman during the war in Afghanistan. The greater media access in this conflict has been ''going great,'' he says. Photos by Chris Tyree / The Virginian-Pilot.ABOARD THE TRUMAN -- He was the voice of the last war, standing before the Pentagon press corps almost daily to update the world about the progress of U.S. forces invading Afghanistan. Now he's at war, in charge of two Norfolk-based carrier strike groups -- known as battle groups before the chief of naval operations recently...

<p>Fears concerning the viability of the GPS guidance system have surfaced in the media following a report Tuesday that coalition forces have positively identified six GPS jamming devices employed by Iraqi forces. Possibly just a fraction of the hundreds of small, Russian-made GPS jammers that Iraq is thought to have, this news is especially worrisome as the war moves into what may be its most dangerous phase — attacking Republican Guard troops in and around Baghdad.</p>

New Air Force Missile Passes Final Test .c The Associated Press EGLIN AIR FORCE BASE, Fla. (AP) - A new, low-cost cruise missile flew through a window and destroyed a two-story test house in its final test flight this week, clearing the way for possible use in Iraq, an Air Force official said Friday. The Joint Air-to-Surface Standoff Missile, or JASSM, next is scheduled for operational tests before going to combat units in September, but it could get to them much sooner, said Gerry Freisthler, lethal strike program director for the Air Armament Center here. The missiles are manufactured in...

U.S. Army awarded contracts to Russian GPS jammer vendor The U.S. Army awarded $192,000 in contracts in 2002 to a Russian company identified in news reports as a supplier of Global Positioning System (GPS) jamming equipment to Iraq. Moscow-based Aviaconversiya Ltd. has denied selling the jamming equipment to Iraq, according to the news reports. Officials there couldn't be reached for comment this week, despite repeated attempts by Computerworld to do so. On Tuesday, President Bush personally complained to Russian Premier Vladimir Putin about the sale of Russian military equipment to Iraq, according to White House spokesman Ari Fleischer. In a...

THE WALL STREET JOURNAL: BELARUS SELLS ARMS TO TERRORISTS 11:19, 29/04/2002 In his recent article for the popular “The Wall Street Journal” Mark Lenzi wrote that terrorists get weapons from the very center of Europe – Belarus. This country, he writes, was called by the US Secretary of State Colin Powell Europe’s only rogue state. During the forthcoming talks between Putin and Bush this issue had to be included into the meeting’s agenda. It is namely through the solution of the Belarusian issue that Kremlin may help Washington combat international terrorism. George Bush’s Administration needs to work out a strategy...

Wednesday, Mar. 26, 2003. Page 1 Kremlin Fires Back At Bush By Simon Saradzhyan and Nabi Abdullaev Staff Writers The Kremlin fired a new salvo in the battle of words between Moscow and Washington over Iraq on Tuesday, insisting that it was President Vladimir Putin rather than his U.S. counterpart who had initiated the discussion of alleged sales of Russian defense equipment to Iraq during their last phone conversation. The U.S. administration fired this week's first shot when White House spokesman Ari Fleischer announced Monday evening that President George Bush had called Putin earlier in the day to complain...

The United States might face a hard road in its war against Iraq. But U.S. technology has already won a victory over Russian-origin military systems in the arsenal of President Saddam Hussein. U.S. officials said the American military has prevailed over Russian systems and technical expertise provided to Iraq. They said the Russian supply of satellite jamming and other electronic warfare systems has not affected allied operations against Iraqi forces.
