Signal Sentry 1000, an Exelis product that detects and locates GPS interference sources in 3-D by using longitude, latitude and altitude has demonstrated successful results during a planned field testing event held last week at the Vidsel Test Range in Sweden.

Taking advantage of the range’s remote location, Exelis was able to conduct tests of its Signal Sentry 1000 product using controlled jamming. The test was conducted without disrupting the GPS signal relied upon by civilian and military operations outside of the test range location. The test employed eight sensors positioned in an array pattern and showed that Signal Sentry was able to successfully detect and locate the jamming source. Having demonstrating interference detection and location capability, Signal Sentry 1000 can be deployed to collect actionable intelligence for law enforcement and protect GPS signal-dependent critical infrastructures.

Signal Sentry 1000 technology is a network of threat-detection sensors, which is part of a centralized server executing Exelis-developed proprietary location algorithms. These sensors can be strategically located around different types of critical infrastructure, such as shipping ports, utilities and government facilities to automatically sense and locate any intentional or unintentional GPS jamming source. Should a threat be detected, users would receive location information and actionable intelligence in order to determine an interference-mitigation plan.

“Exelis developed Signal Sentry 1000 to help protect critical infrastructure and to deliver intelligence to law enforcement operations that depend upon GPS availability,” said Mark Pisani, vice president and general manager of precision instruments and positioning, navigation and timing for Exelis Geospatial Systems. “Achieving this field test milestone proves that our detection technology works. The next step is to evolve this technology for our military customers.”

Signal Sentry 1000 builds upon Exelis expertise in the field of GPS and positioning, navigation and timing. Exelis payloads and payload components have been on board every GPS satellite for nearly 40 years. Today, Exelis is involved in GPS modernization initiatives, building tomorrow’s GPS III satellite constellation by developing and integrating the navigation payloads. Exelis is also providing navigation processing components, precision monitor station receivers, and key components of the system security design for the GPS Operational Control System, known as OCX.
