Abstract :
HINS, a prototype of a high-performance, fault tolerant navigation system is being developed for Canada´s antisubmarine warfare helicopter. HINS consists of three primary navigation subsystems an F3 INS (inertial navigation system), a five channel P-code GPS (global positioning system), and a Doppler velocity sensor and three secondary sensors (a strapdown magnetometer, a vertical gyro, and an air data system). The system is designed to blend the complementary strengths of component sensors, and to provide graceful degradation of performance in the event of failure or slow deterioration of these sensors. During normal operation, the Doppler and secondary sensors are calibrated to enhance performance during degraded mode operation. A multilevel failure detection and isolation scheme monitors sensor health and identifies faulty system components
