　　As every country's tanks enter to show their strength, it is obvious that the United States.As early as March 2000, the United States and Australian military carried out a joint GPS jammers locator research in remote Woomera.Such a GPS jamming strategy should not come as a surprise, given the reality of the US.

　　But in a conflict in which pseudolites cannot be safely deployed, ground forces could go astray or misdirect their fire if they encounter a minefield of expendable, hockey-puck-size GPS jammers, each of which could disrupt the GPS signal within a one-kilometer radius.These new satellites would transmit a GPS signal eight times stronger than the current signal, which means that any potential jammers would have to increase in size and complexity.

　　Grants Pass, a manufacturer of GPS jamming equipment used in training.Hendershot said: "Military signals are hard to destroy, but they are still easy.In fact, small GPS jammers can be built by any hobbyist with a spare $400 to invest in electronic components, using plans supplied by the online hacker magazine Phrack, for example.Sometime later and to the amusement of Greek defense officials, reports the journal Military Review, it was revealed that French agents were remotely activating small, one-foot-high GPS jammers to disrupt the GPS signal when British and U.

　　Such devices can easily disrupt a commercial GPS signal and possibly a military GPS signal, even though the latter is encrypted with a code that changes on a regular basis.Because these small jammers can interfere with people on the ground.Soldiers' GPS receivers have no backup navigation system.South British tanks can't get GPS navigation signals.

　　Experts like Hendershot point out that before that, GPS was very fragile.Pseudo-satellite and standby inertial navigation systems mean that smart bombs and cruise missiles may reach their intended targets.Iraq reportedly also purchased as many as 400 small GPS jammers from Aviaconversiya prior to the outbreak of hostilities in the region, although it is not known whether any of these were used.
