Combination of CRPA Technology and Intelligent Signal-Processing
Cobham Aerospace Connectivity has been awarded a contract by the UK MoD to research advanced anti-jam techniques for the protection of navigation signals received from the Global Navigation Satellite Systems (GNSS), the company announced on 30 March.
Cobham will conduct research to develop methods of providing assured and resilient position, navigation and timing (PNT) information derived from the GNSS constellation. Cobham was thought best-placed to address the MoD’s needs through its extensive background in advanced antenna technology and sophisticated signal-processing capabilities.
The research is set against a backdrop of increasing reliance on GNSS navigation signals in the nation’s critical infrastructure and national security, as well as the frequent interruptions of signals, caused either accidentally or intentionally. The more sophisticated interruptions involve falsification of the navigation signal information, potentially motivated by piracy, or those seeking to achieve civil disruption and/or military advantage.
The MoD-backed research feeds into the company’s goal of taking anti-jam capabilities already developed and evolving a miniaturised system capable of providing advanced protection of the received signals. The resulting 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 and assured navigation information, but also to derive important signals intelligence and domain awareness information regarding the source and nature of the interference and the best means of mitigation.
“This contract award recognises Cobham’s status as a major UK provider of anti-jam systems as well as our long history and deep experience in the areas of navigation antennas and satellite connectivity,” commented Neil Tomlinson, Vice President Sales and Business Development at Cobham Aerospace Connectivity.
