GPS jammers can ignore false signals

With the increasing popularity of GPS Jammers, the military hopes that its missiles can ignore false signals. The Army is looking for “novel technologies that use existing antenna configurations or make minor changes to the vehicle’s RF front end to determine the direction of malicious interference sources (i.e. traceable imitation signals) reaching the missile platform (which may be extended to other platforms).”, according to The above call is from the Small Business Innovation Research Center.

The Army said that the solution must “have hardware and resources that are generally feasible or available on missile platforms to implement airborne damage control procedures that interfere with poor signals on mobile phones.” “Available hardware may include built-in CSAC (chip-level) Atomic clock), FRPA antenna, and possibly multi-element CRPA antenna module (covariance estimation available). Software method is recommended, but minor hardware upgrades can be considered. ”

The Army pointed to a newly developed algorithm that will enable the missile to detect jammers and determine their location, for example. B. Multi-signal classification (MUSIC). These algorithms focus on the unique properties of GPS jammers. “For example, trackable jammers (also called spoofers) are likely to create an entire GPS-like constellation and broadcast from a common. Therefore, these signals will produce an extended delay of the entire constellation (ie, in the flexible tube relative to the Line-Other defined malicious interference characteristics may include increased energy (i.e. jamming signals), clock drift/offset chromaticity, inter-satellite interference, etc.”
