UK MoD Awards Anti-Jam Signal Contract to Cobham

Cobham Aerospace Connectivity was recently awarded a contract by the UK Ministry of Defence’s (MOD’s) Defence Equipment and Support (DE&S) to research Advanced Anti-Jam techniques for the protection of navigation signals received from the Global Navigation Satellite Systems (GNSS).

The contract will see Cobham conduct research to develop means to provide assured and resilient Position Navigation and Timing (PNT) information derived from the GNSS multi-constellation. 
 
According to a company statement, Cobham is well placed to address the UK MOD’s needs through its background in antenna technology and signal processing capabilities.
 
The research is set against a backdrop of increasing reliance on GNSS navigation signals in the UK’s critical infrastructure and national security and the frequent interruptions of the signals either accidentally or intentionally. The more sophisticated interruptions involve the falsification of the navigation signal information for nefarious reasons such as piracy, civil disruption and military advantage.
 
The DE&S-backed research feeds into the company’s goal of taking already developed Anti Jam capability and developing a miniaturised system capable of providing advanced means of protection of the navigation signals received from the GNSS multi-constellation network.
 
The anti-jam system will combine the use of advanced Controlled Radiation Pattern Array (CRPA) antenna technology with intelligent digital signal processing techniques not only to ensure reliable navigation information, but also to derive important signal intelligence and domain awareness information regarding the source and nature of the interference and the best means of mitigation.
