US armored personnel carriers will receive electronic defense devices

The U.S. Army reported that installation of advanced anti-jamming devices on light ground forces armored vehicles has begun. Devices are able to provide reliable GPS / GNSS navigation even in the conditions of jamming by electronic warfare. The threat of jamming GPS systems is a serious threat to the army, which is actively using high-precision weaponas well as navigation and guidance systems.




Currently, the threat of using electronic warfare equipment to jam GPS is one of the worst nightmares for the U.S. armed forces, as interference can knock troops out of their way, disrupt navigation or prevent the use of precision weapons on the battlefield.

Over the past month, the sixty-two first complexes were mounted on armored personnel carriers deployed in Germany. A few thousand more are planned to be installed on the vehicles of the European Command of the United States by 2028.

The system of guaranteed accuracy of navigation and data synchronization, known as MAPS, was developed to ensure reliable reception of satellite signals on devices mounted on platforms of lightly armored vehicles, such as BTR Stryker. This system is part of the Pentagon’s latest efforts to prepare the army for a meeting with a high-tech adversary such as Russia and China.

It is expected that the MAPS system will be installed on more than 300 Stryker BTR vehicles from the 2 Cavalry Regiment this year.

- said the representative of the military department Willy Nelson.

The army also plans to equip the system with armored brigades and deploy them on Bradley combat vehicles, M1 Abrams tanks and M109 Paladin self-propelled howitzers. After installing the technology on these “priority vehicles”, the ground forces will assess the need to install the device on the so-called second level vehicles.

One “really good system”


In the past, armored vehicles used on each piece of equipment several advanced dual-frequency GPS receivers, also known as DAGRs, with the hardware necessary to decode encrypted GPS signals with a P-code. MAPS replaces several DAGR devices with “one really good system.”

In the event of a signal interruption, MAPS includes an automatic single-point mode based on a change in the detection range of points from the base depending on the speed of movement.

Simply put, maps continue to work whenever the GPS signal is weakened or compromised.

said Colonel Nicholas Kiutas, a satellite technology project manager.

At this stage of prototyping, the latest version of the GPS receiver can send protected data to satellite data over a wired or wireless network. It is also expected that in the near future will be presented modified versions of next-generation devices.

    Slowly they begin to reach)))

      Is the US going to march across the tundra or taiga?

    I do not understand! They knock down GPS signals without drowning them, but by sending FALSE signals at the same frequencies, but stronger! The system does not recognize the signal as false, and the coordinates are not correct.

    Nonsense, and this system, like jeepies, can be tricked or hacked.

    To protect yourself from electronic warfare, you need not have electronics in the APC. Then there will be nothing to influence. lol

      Then you need to transfer to the equipment, which at one time produced ChTZ.

    In principle, if you check the ZhPS with an inertial, then there are no problems. And not expensive. Difficult question. I think that providing positioning with an accuracy of tens of meters is not difficult. Milking ammunition is more critical. For technology, no.

      For ammunition with continuous movement and a simple flight path, positioning with an accuracy of tens of meters is not difficult to achieve, but with the technique of whipping - turns, turns, stops, all this contributes to the accumulation of errors, satellite navigation is used for correction, and it is just replaced by false values

        I meant a little different. If an APC in the process of movement has accumulated an error of 200 meters, then this is not a problem. And if by these erroneous data they requested a blow to the identified target, then there will be no defeat. The ammunition will leave either in the actual coordinates or the identity will also accumulate an error. And in fact, the slower, in comparison with the ammunition, equipment will save an error, by inertial less.

      Drive cars through the stars, no electronics needed.

    I'm in shock))) How did we, who served on the BTR / BMP, do without GPS ??? And the route was drawn in pencil on a piece of paper. And if you jammed the connection - switched to flags, signal flares or (most often) to “voice” - the louder you scream, the further you hear))) Now everything - there is no GPS, no victory !!!!
