The Russians have their own GPS system called Glonass.
In regards to the Mig-31 the russians would not develop GPS guided munitions without some sort of alternative system in place which to date has not been avalible. That may change with india signed on and its supposed to be fully operational by 2009.
What this post hints at is the ability to blind GPS guided systems with either jamming or EMP from exploding a nuke high in the atmosphere.
Indeed, it was the potential vulnerability of GPS to jamming that prompted Iraq to purchase a number of GPS jammers from Aviaconversiya Ltd., a Russian company that has been hawking GPS jammers at military hardware shows since 1999. The high-priced and high-powered GPS jammers offered by Aviaconversiya were said to be able to jam GPS signals for a radius of several miles. The Iraqi military used at least six of these high-powered GPS jammers, which cost $40,000 or more each, during the war. All six were quickly eliminated by U.S. forces over the course of two nights. Officials won�t provide details, but considering the speed with which they tackled the problem, the Iraqi GPS jammers may initially have been somewhat effective.
Iraqi efforts at jamming may also have been thwarted by a novel, signal-boosting technology--deployed in Iraq under a shroud of secrecy--that overwhelmed the GPS jammers. Airborne pseudo satellites, nicknamed "pseudolites," installed on Global Hawk or Predator unmanned drones would have created a miniature GPS constellation over Iraq. These pseudolites would have captured the weak GPS signals from space and then relayed them, at substantially higher power and at closer range, to airborne bombs and missiles or to forces on the ground. Like the satellites in space, four pseudolites would be required to plot a navigational solution. www.sciam.com...
The next-generation GPS III system is expected to have about 500 times the transmitter power of the current system, multiplying its resistance to jamming. With a constellation of 30-32 satellites, GPS III will have Second and Third Frequencies to contain civilian signal, (L2 = 1227.60 MHz) & (L5 = 1176.45 MHz), more robust signal transmissions, and provide real-time unaugmented 1 meter accuracy.
can you explain what you mean by a "“modified” GPS navigation system"? Did you modify it yourself?
Are you near a reactor or base? There have been rumors that areas around Nuclear sites and bases can and have been scrambled or degraded on a selective basis.....
I doubt it. iraq tried using jammers that were supplied by the new Soviets and did not have much luck.
US Army awarded contracts to Russian GPS jammer
The US Army awarded $192,000 (£122,000) in contracts in 2002 to a Russian company identified in news reports as a supplier of Global Positioning System (GPS) jamming equipment to Iraq.
The reports said Moscow-based Aviaconversiya has denied selling the jamming equipment to Iraq.
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.
After a de rigueur denial of contacts with Iraq, Aviakonversiya's Antonov shared the following with "Vremya novostei" on 25 March: "We exhibited our first [GPS jamming] transmitter at the Zhukovskii air show in 1997. The Americans were horrified. End of story, as they say -- their high-precision weaponry can be wrecked quite simply."
How effective are the jamming devices? "Aviation Daily" reported on 22 September 1997 that, according to FAA spokesman Hank Price, "the type of device being marketed by Moscow-based Aviaconversia is 'nothing new,' and there are 'hundreds of these devices' on the market." A 17 November 2000 article in "Defense Daily" reported that U.S. defense contractor Lockheed Martin was sufficiently concerned, however, to develop a system to counter GPS jammers. The article went on to explain: "Russia's Aviaconversia currently markets a four-watt GPS jammer that only weighs about 19 pounds [8.6 kilograms] but can deny GPS reception for about 125 miles [201 kilometers]." Avoiding further specifics, "Defense Daily" merely noted that Lockheed Martin's G-STAR antijamming system ended its development phase and entered testing in 1999.
Few in Russia were inclined to cast doubts on the jammers' effectiveness. In fact, a 25 March article in "Nezavisimaya gazeta" argued that it was the jamming systems' efficacy that sparked protests from the stunned U.S.-British coalition. Citing anonymous "experts," the newspaper claimed that the Iraqis' use of jamming technology "came as a complete surprise to the attackers, who above all else feared chemical and biological weapons." The effects on the coalition's weaponry were even more surprising, as "instead of high-precision direct hits, in a number of cases 'smart' bombs and Tomahawk cruise missiles struck civilian targets far from where they had been aimed."
Is it possible for one eccentric professor to neutralize the enormous years-long labors of thousands of highly skilled scientists, engineers, and workers to develop precision "smart weapons" at the cost of tens of billions of dollars? "Easy," as they say in Russia. A St. Petersburg scientist, Dr. of Technical Sciences Valentin Vladimirovich Kashinov, has managed to do just that. With his inventions he has virtually "shut down" western efforts to create 21st century weapons, precision "smart" weapons which find targets based on information from satellites, and thus are today considered nearly one hundred percent effective. Valentin Kashinov made his "contribution" to the defense capability of the US and NATO, practically knocking out the latest, multi-billion dollar military space system, and at the same time raising doubts about the advisability of Washington's development of a national ABM defense.
Summoning Missiles to the Oven
In the heat of massed missile strikes on Belgrade and Yugoslavian air defense radar positions in the spring of 1999, the telephone rang one night in a St. Petersburg apartment.
It was the chairman of the radio club of Yugoslavia, Khranislav Milocevic. Valentin Kashinov answered. The Yugoslav described the great destruction and casualties caused by strikes of NATO aircraft, "HARM" air-to-ground missiles, and Tomahawk cruise missiles. Milocevic asked for help in fending off these bombardments. Valentin Vladimirovich immediately inquired if they had any microwave ovens. This was followed by a puzzled silence, and then: "Of course!" Kashinov advised that they get some ordinary microwave ovens and aim them upwards, with doors open, around an installation they wanted to protect, and then turn them on. Khranislav understood at once. The fact was that an American HARM missile would home in on any strong source of radio emission in the 400-10,000 MHz range, exactly the range of conventional household microwave ovens. Literally the next day following this conversation, NATO forced bombed their own embassies in Belgrade.
Stealth Armor Covers the Whole Country
It should be noted that during the NATO bombing of Yugoslavia, the Russian scientist sent Brussels a description of the anti-weapon against the NAVSTAR GPS system, warning that if they did not cease their outrages, he would publish methods for "rubbing out" other navigational systems as well, for example TACAN, DME, LORAN, etc.
And these means enormous losses for the West. It has been calculated that because of Kashinov's mini-jammers, which virtually put the NAVSTAR system out of commission, the Americans lost 80 billion dollars and 20 years of work by their scientists. According to available information, today they are trying to develop a new system, since the GPS system cannot be improved, and this will require time and money. So the US will hardly be able to develop an ABM system with guaranteed effectiveness.
You see, the arsenal of anti-weapons includes devices which create short, or as they are called, "nanosecond" pulses of electromagnetic radiation of enormous power, exceeding the power of a nuclear burst. When they act on modern high-tech microcircuits (transistor diameter less than the thickness of a human hair), in the best case these emissions create system glitches, and in the worst case they put the microcircuits out of commission. Naturally, the weapon controlled by the computer which is destroyed by the pulse is also knocked out, be it a missile, ship, or tank.
Portable space navigational system jammers produced by a Russian company were first displayed at the Moscow International Aerospace Show in 1997, provoking genuine shock and horror among military users of these navigation systems.
