Civilian Interference Detection and Estimation Receiver (CIDER)

Toyon has teamed with two utilities to survey the use of civilian GPS receivers in the energy and communication sectors, and to determine their vulnerabilities to intentional interference, including narrowband and wideband jamming, spoofers, repeaters, and RF-based 'software attacks.' As part of the survey, the characteristics and weaknesses of the deployed civilian receivers will be determined and methods of detecting, identifying, and locating sources of GPS interference within the electrical and communication networks will be identified. Based on the survey results, Toyon will design a system for interference detection, identification, and geolocalization (I-DIG).

I-DIG will comprise a network of receiver nodes and a centralized geolocalization filter. Each node will include a direction-finding (DF) GPS receiver, which is the most critical component of the I-DIG system. Toyon's patented DF GPS receiver technology has been tested and demonstrated in realistic environments and has a TRL of 6. The collaborative geolocalization algorithm has been developed over the course of numerous programs and is at a TRL of 5. At the conclusion of the Phase II effort, which will include a complete system demonstration in a relevant environment, we anticipate that both components will have a TRL of 7 and will be ready for deployment.

The proposed technology has the potential for immediate integration into our country's electrical transmission and communication networks. Since Toyon's DF GPS receiver is also capable of anti-jam (AJ) and anti-spoof GPS processing, it is applicable to any civilian application that desires protection against intentional and unintentional interference.
