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 world’s smallest anti-jamming and anti-spoofing GPS.
In a few decades, GPS has become an indispensable tool for armed forces, whether to steer vehicles, target missiles or simply locate the forces on the ground. The new military GPS announced by BAE Systems is the smallest receiver in the world. The size of a postage stamp, it is resistant to jamming and signal spoofing.
US military GPS systems use the new M-Code system, a more secure signal designed to be independent of the signal GPS General 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 interference with the C / A system used for general public GPS.
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-usurpation. The device is in the process of being approved, with full production scheduled for 2022.
