In order to counter enemy attempts to create confusion by jamming or spoofing the GPS signal, the US military designed the M-Code system. A new M-Code receiver developed by BAE Systems is the smallest anti-jamming and anti-spoofing GPS in the world.
US military GPS systems use the new M-Code system, a more secure signal designed to be independent of theGeneral public. It uses the same satellites, but it is broadcast from a directional antenna in addition to the usual wide-angle antenna. This allows a greater intensity in order to be able to pass through the jamming systems, without creating with the C / A system used for .
A receiver compatible with existing equipment
This therefore requires special equipment. This new GPS receiver, the MicroGRAM-M measures 25.4 x 31.75 x 6.99 millimeters. According to BAE Systems, it has the same dimensions as its predecessor, and has been designed so that it can be easily swapped into existing devices. In addition to being the smallest of the M-Code devices, it is also the one with the lowest power consumption.
The MicroGRAM-M also provides fast signal acquisition, improved security, and anti-jamming and anti-. The device is undergoing approval, with full production scheduled for 2022.
