“To Counteract Russia and China”: US Introduces Antennas to Protect GPS Signal

37
The Pentagon has developed antennas that can receive GPS signals even in the presence of jamming. However, the main issue was the mass introduction of technology and equipment calibration for thousands of platforms. This was reported by Defense News.

GPS has actually become the "gold standard" for satellite navigation and target designation. However, modern electronic warfare equipment is able to drown out the signal or give a false one, misleading the signal receiver, which can lead to fatal consequences.

GPS, GLONASS, Chinese Beidou play a huge role in the modern battlefield. Without them, it is difficult to imagine high-precision ammunition, ships will have to return to traditional methods of navigation, and troops will have to find the point to which you must follow. However, for fighters - especially the 4 ++ and 5-th generation, as well as UAVs - GPS is not just a convenience, but a fundamentally important part of the combat system.

To counter Russia and China


The Pentagon, which recently considers the fight against an equal or superior opponent as a priority - and China and Russia are identified as potential enemies - decided to respond to a possible problem. Realizing the superiority of Moscow in the field of electronic warfare, the military department, together with the US military-industrial complex, developed a system that will allow fighters to receive a GPS signal even when it is jammed.

At the heart of the future noise-immune navigation and target designation system are technologies for creating an antenna with a controlled radiation pattern in the vertical plane or CRPA. The principle of operation of such antennas is quite simple in theory. The signals arriving at the receiving device usually have a different appearance due to the passage of different distances in the atmosphere. In addition, along the way, the signals are distorted and come at different angles. All this allows their selection to be made, highlighting useful ones, and weakening those that interfere.

All next-generation military platforms seek to use precisely these antennas. CRPAs work much more efficiently under adverse conditions.

- commented Tyler Hohman, director of products for Orolia Defense & Security, his vision of the situation.

The main thing is calibration


The product requested by the army itself is already ready. However, the process of introducing technology, which should be installed on thousands of platforms in the near future, remains a fundamental issue for the Pentagon. The US military should determine if the technology works with platforms that the Pentagon already has or is about to acquire in the near future. And then modern modeling and simulation programs come to the forefront that can calibrate the system without sending antennas to the laboratory.

At the annual conference of the US Army Association, which opened on October 14, Orolia demonstrated the new BroadSim Wavefront simulator. According to Hochman, the company has already sold one such simulator to the army and expects to complete the delivery by the end of the year. The army will use the simulator to calibrate mounted and dismantled next-generation communications systems.

The company claims in the third quarter military orders for solutions in the field of so-called elastic (fail-safe) positioning, navigation and synchronization (PNT) almost tripled as the US Army pays more and more attention to anti-spoofing technology. PNT fault tolerance assumes that no data source can be completely reliable, so the answer lies in combining them into a single whole.

          In other words, the EW source for the false signal must be raised higher. Ideally, launch an EW satellite laughing

        EW is very limited in range. And it must be continuously improved in order to stay ahead of defenses and countermeasures. Although there are those on the VO who are ready to shoot down satellites at an altitude of 20 km. Probably right from the sofa.

          To cover stationary objects, appropriate equipment with the necessary power can be installed, BUT! Now inert guidance systems are again on the rise! Good accuracy, dimensions and power equipment, acceptable for small vehicles. The price is not so high for the military .... not every shell and mine, but it seems so far!

          The EW complex "Divnomorye" is designed to cover command posts, groupings of troops, air defense systems, and important industrial and military-political centers within a radius of 1000 kilometers from enemy radar detection. This complex can "clog" the equipment of the E-3 AWACS, E-2 Hawkeye and E-8 JSTAR radar aircraft, helicopters and drones, cruise missiles, satellite radar systems, ground systems with powerful interference.

          This is again the struggle / war of the inquisitive, sophisticated minds of the designers.
          I remember the first detector receiver, assembled in 60 years ... (my father thought that it was necessary to learn from the BASIS), there was a rattle, a squeaker, a squealer ... a military unit after all, an object of air defense missile forces in distant Siberia. ... but how much joy it was to hear someone then!

      Theoretically, an idea can be workable. But by an order of magnitude increases the time of the map for smart ammunition and weapons ... GM, it’s not very suitable anymore.
      Secondly, what does it mean "signals have a different form"? !!! Well, I do not understand at all, the Doppler shift, chtol? * LOL * The frequency is the same, the amplitude ... Nonsense, you first bring the satellite signal to any point on the planet to the same amplitude standard - it is fundamentally unsolvable. Again, on the way from the satellite, interference is possible - from cloudiness to a magnetic storm, how to drive this into the selection algorithm?
      And forget about the angle of incidence - a soldier sitting on an armor sneezes - a cone of such a narrow antenna - will run away, and you won’t even catch the signal with a TOO narrow beam, even now this is one of the main disadvantages of satellite communications

        Secondly, what does “signals have different forms” mean?

        well, Americans can hardly be called ignorant. The atmosphere (especially with the layer of the ionosphere) in its most general form will be a spatial filter that makes its own "contribution" to the signal. And the amplitude and phase distortions in the signal spectrum can apparently be distinguished and said - the signal passed its 100 km through the upper layers, or emerged from around the corner.

          Not necessary. Any grill, mirror, or any other antenna has “malevolent” side lobes, albeit weak. Required. They can be used as a hindrance. Moreover, where is the satellite, and where is the jamming station, and even more powerful.

        The simplest is to attach jammers to anti-aircraft missiles, let them go to the maximum height, instead of a babakh, there a helium ball with a jammer is shot, a kilogram in 20, for 10-15 minutes of work. Enough to protect the object.

      The Pentagon has developed antennas that can receive GPS signals even in the presence of jamming.

      The antenna, in itself, is only suitable for pulling it on the roof.
      Everything else to suppress interference is performed in the receiver path.
      And everything else - "from the evil one"

      Interesting idea. Create highly directional antennas that receive signals from points close to the zenith. As then, in principle, space navigation will function, since its idea is precisely to simultaneously receive several signals from stationary satellites, all the time in orbit, including at low altitudes close to the horizon. The determination of coordinates is based on this, when a signal is caught from three (preferably four) satellites and the location coordinates are determined from these signals. Probably, it is theoretically possible, but then the number of satellites should be in the tens of thousands, so that there would be a sufficient number of them above the head of an object located anywhere in the world.

      What is on your forehead, what is on your forehead. The main thing is to crow, "SATELLITES !!!".
      Musk makes loot on promises, paying and buying his representatives in structures that allocate him assistance and benefits. But you didn't bother to read WHAT satellites to launch in the amount of several thousand. "Free Internet. Provided, of course, the acquisition of equipment that provides communication with his space network. And with the ability, at the beck of the American hawks in power, to block such a connection in a second, because a switch will undoubtedly be built into the drivers of this piece of hardware. So, it is interesting to know where this network will take you, to what booths, if you start using the Internet on the way to visit relatives in Germany. What does this have to do with navigation, since STATSIONAR and low-flying satellites are essentially different things. I'm not even talking about the equipment itself, stuffed into one or another satellite.
      You, anyway, the main thing is to crow, and there at least do not dawn.

      Just the opposite. The interference source should be brought as close as possible to the RECEIVERS of the navigation system signals. That is, they must be on Earth, have terrestrial power sources (which are practically unlimited either in power or in terms of operation, which distinguishes them from sources of stationary satellites flying in orbit at a distance of 36 thousand km.). Maintenance, re-adjustment, modernization of ground jammers is a simpler task than the same in the distance and inaccessibility of the Cosmos. To the benefit of this option, Nature itself works. The signal is attenuated in proportion to the square of the distance. A signal with a power in kilowatts, but at such a distance can be guaranteed to extinguish with the same power, but located nearby.
