GPS Signal Jammers Stymied by Exelis
Exelis' Signal Sentry 1000 device detected and located GPS interference sources in 3-D by using longitude, latitude and altitude, during recent field tests 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…
