GPS Degraded and/or Denied Precision Navigation for Munitions

To address navigation in environments where GPS signals are degraded or denied, Nu-Trek is proposing to develop a highly-compact, multi-channel, multi-frequency receiver. The receiver will include a high anti jam GPS receiver as well as several other channels [1.1-1.6 GHz (GPS), 420-450MHz (C2), and 225-450 MHz (EPLERs)]. The compact form factor and the anti jam capability exceed the state of the art, providing an enabling navigation tool for small munitions, where space is very limited. The multi bandwidth receiver leverages Nu-Trek"s high anti jam RF ASIC chip and a Raytheon anti jam DSP, which enable both the high performance and the compact form factor. Heading the Nu-Trek team are Ray Eastwood, Wais Ali, and Kyle Lyson, who developed the Nu-Trek front end. Heading the Raytheon team is David Lewis, the Director of Raytheon"s GPS Advanced Products Group. Dr. Yannis Paschalidis, is an expert in algorithms with specific expertise in GPS denied environments. This multi-disciplinary team, that combines both hardware and algorithm experts will be able to effectively address both signal acquisition as well as interpretation. The collaboration with Raytheon, one of the world"s leaders in guided munitions, provides a direct path to insertion into waeapon platforms.
