The Visible Infrared Imaging Radiometer Suite (VIIRS) is a sensor designed and manufactured by the Raytheon Company on board the polar-orbiting Suomi National Polar-orbiting Partnership (Suomi NPP), NOAA-20, and NOAA-21 weather satellites. [1] VIIRS is one of five key instruments onboard Suomi NPP, launched on October 28, 2011. [2]
Field commanders using tactical radio equipment, such as the AN/PRC-117F Multiband Manpack Radio, can directly communicate with the satellite in the ultra high frequency (UHF) band. [ 13 ] [ 14 ] [ 15 ] TacSat-3/ARTEMIS observations of the National Mall and the Kilauea Volcano to support technical validation of the sensor have been released in ...

X band functionality (8 to 12 GHz frequency range) is optimal for minimizing low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination, and the target illumination for SM-2 and Evolved Sea Sparrow Missiles (ESSM).
TPY-2 radar in travelling configuration View from the back on a deployed TPY-2 radar. The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array [1] [2] X band surveillance radar designed to add a tier to existing missile and air defence systems.
The radar is built by Raytheon as a follow-on to their AN/APS-149 Littoral Surveillance Radar System (LSRS). The AAS has its roots in the highly classified AN/APS-149 LSRS, which was designed to provide multi-function moving target detection and tracking and high resolution ground mapping at standoff ranges covering land, littoral , and water ...
A Selective Availability Anti-spoofing Module (SAASM) is used by military Global Positioning System receivers to allow decryption of precision GPS observations, while the accuracy of civilian GPS receivers may be reduced by the United States military through Selective Availability (SA) and anti-spoofing (AS).

Tip and cue systems utilize a network of satellites equipped with complementary sensor technologies to track moving objects in real-time. The method involves detecting a target with a primary sensor, such as an infrared or photographic sensor, which then cues secondary sensors on the same or other satellites for more detailed monitoring.
Raytheon, often in conjunction with Boeing, Lockheed Martin or Northrop Grumman, is also heavily involved in the satellite sensor business. Much of its Space and Airborne Systems division in El Segundo , CA is devoted to this, a business it inherited from Hughes .
