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.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
