The GPS satellites are not so easy to target as people think (Installing "Trophy-system into satellites)

GPS (Global Positioning Satellite) is a very good target for ASAT (Anti Satellite Weapons) because this satellite is giving the data for positioning for satellite-guided weapons like JDAM (Joint Direct Attack Munition) and GPS guided bombs and missiles. Those weapons allow that combat aircraft would close in the target in free angle, and that makes those weapons so effective.


The GPS is the easiest way to locate the position of the own troops, warships, and aircraft. GPS is also used in the safety systems of some special cargo, what are the risk to get stolen like money and the nuclear weapons. This system sends the location information of those things, and that will make the stealing that equipment very difficult.  If the security personnel would push the alarm button, that would send the information of emergency to the security company. And that's why GPS is the very vital role in the private or governmental security.


But if somebody would destroy the GPS-satellites the strike capacity of NATO task force will decrease, because the tactical support aircraft would need the precise information of own troops position. And that's why GPS-satellites are so important in those operations. But the use of ASAT-systems would cause big danger for those satellites. If the GPS-satellites are equipped with similar ADS-system, called "Trophy", what is used in the M-1 "Abrahms" tanks would that increase the probability of survivability, if the satellite would be getting attacked.


"Trophy"-type ADS is actually a microwave system, what uses multiple IR (Infra Red) sensors to detect incoming missiles, and then the microwave transmitter turns to those missiles, and the warhead of those missiles would be detonated too early. In the satellites that system might seem like some Sci-Fi space battle vehicle's gun turret. The similar system can easily install to the GPS-satellites, and that would allow destroying those incoming ASAT missiles. This would make some of those weapons unable to operate correctly. And that system would also be used against other satellites.

The ”Trophy ” system and active protection of the tanks and other vehicles

Why I mentioned the U.S ”Trophy” system in the headline, is that I don't remember the name of similar Russian weapon system. This kind of active denial systems are coming to tanks, and their mission is to destroy missiles before the ammunition touches the tank. In modern denial, the system is the battery of arrow, what is guided by sensors, what uses infrared and radar to locate the incoming antitank weapon. When the antitank missile is located, the ADS (Active Denial System) would shoot it with an arrow and it works like CIWS-gun on the deck of warships.


The structural problem of those weapons is that they must be lightweight, that those weapons can turn fast enough against an incoming missile. That's why there is used flechette-claymores, what can launch their flechettes as controlled salvos. This structure allows those weapons turn extremely fast, and the cheap microchips are making possible to create very small caliber guided ammunition, and maybe the ”smart” bullets, what means miniature, rifle caliber missiles are first in use at this kind of weapons.


Also, this kind of systems would locate hiding enemy soldiers, and those active denial systems might use also taking off snipers. The active denial systems are quite a new idea to protect tanks against anti-tank rockets. The first tests of this kind of systems were ”active explosive armor”, where the tank was covered by explosive plates, what would explode the warheads before they face the armor. In this case, the system is equipped with artificial intelligence, what notices if a person is carrying weapons or explosive belts, by using the infrared system, and then it can shoot this target if it has permission to do that. This kind of systems is also installed in combat helicopters to protect them against enemy anti-aircraft missiles.


There must also be plans to use directed energy weapons as the ADS. In this scenario, the tank would have the microwave antennas on its surface. This system bases the idea that the tank would be covered by light, but extremely hard carbon fiber layer. Below this layer are magnetrons, what would be activated when the system sees the incoming missile. And the microwave would destroy the incoming warhead before it faces the tank or ship.


But there are a plans to create more effective and futuristic version of ADS. That bases the microwaves. In this fictional system, the target would be covered by ”the bubble” of microwaves. The bubble consists two internally opposite rotating microwave areas, what would crush the incoming ammunitions. In some plans, even a single soldier would have this kind of active power field around them, and there would be safe against bullets.
