Advanced Interceptor Guidance, Navigation and Control (GN&C) Components

This proposal addresses the need for a low-powered, low-noise, high-sensitivity, jam-resistant P/M code capable GPS receiver which can continuously track a GPS signal under high-g environments. The system incorporates several innovative technologies. First, the system is designed to keep the intrinsic system noise to a minimum. Second, a sensor suite incorporating an inertial measurement unit (IMU) is interfaced to the system and an ultra-tightly coupled algorithm incorporating a nonlinear filter to integrate the equations of motion increases the system sensitivity, allowing it to operate in environments where signal strength is severely. Third, the system is designed to be jam-resistant. In addition, the system has been designed for low power consumption and portable dimensions using commercially available off-the-shelf components. Using such components also helps keep system cost to a minimum while providing the required system performance.
