Exelis Geospatial Systems News

Exelis says it has successfully completed and fully tested six transmitter assemblies, which are integral payload components for the first in a series of the next generation of GPS III navigation satellites. The navigation payload transmitters carry high-powered GPS signals from space to Earth, benefitting military, commercial and civilian users. To ensure the space vehicle navigation payload meets performance requirements over the mission life, Exelis subjected the transmitter assemblies to a rigorous test program which includes random vibration…

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…
