GPS guidance package

Abstract

Summary form only given, as follows. The GPS (Global Positioning System) guidance package program will combine a fiber-optic-based inertial navigator with a miniaturized GPS unit. This system will provide 1 nm/hr stand-alone capability without GPS, and 20 m positioning with GPS. The major objectives of the program include small package size (100 cubic inches, 7 lbs), low power (30 W), and low production cost. Fiber-optic technology coupled with a high-speed miniaturized GaAs GPS receiver provides the key to meeting these program objectives. The all-solid-state nature of this approach also promises significant reliability gains over present integrated INS (inertial navigation system)/GPS systems.<>
