A Fuzzy Integrated Navigation System (FINS) is proposed consisting of a GPS, Inertial Measurement Unit (IMU) and Magnetic Sensing Unit (MSU). In addition to the traditional Inertial Navigation System composed of a tightly coupled GPS-IMU, a tightly coupled MSU-IMU is added along with Fuzzy Logic Adaptive Signal Processing (FLASP ) to process and blend all information. This creates a system which can sustain accuracies even in the face of GPS outages.
