GPS Degraded and/or Denied Precision Navigation for Munitions

ABSTRACT: 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 Radio Frequency Integrated Circuit for GPS receivers. Nu-Trek will develop an RFIC to cover all GPS bands as well as alternative bands for navigation in GPS-denied environments. The RFIC potentially replaces 10s-20s of discrete components, in board-level implementations, required to provide the same functionality and performance. The RFIC exhibits high linearity and high dynamic range at low power. The power consumption of the RFIC has the potential to reduce power by 4X when compared to similar discrete systems. The RFIC"s compact form factor and facilitation of receiver 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 augmented receiver leverages Nu-Trek"s high anti-jam RFIC chip (NT/X-Jam/01) and prime"s anti-jam DSP, which enable both the high performance and the compact form factor. A world class and multi-disciplinary team, that combines both hardware and digital processing experts with manufacturing excellence, will be able to effectively address both signal acquisition as well as interpretation. The collaboration with our prime, one of the world"s leaders in guided munitions, provides a direct path to insertion into weapon platforms.
