Abstract :
The advanced development model (ADM) for the helicopter integrated navigation system (HINS) is built for the Canadian Department of National Defence and tested at the Honeywell Advanced Technology Centre (ATC). The system blends the complementary strengths of its components sensors, resulting in fast alignment and optimum navigation accuracy. A failure detection isolation and reconfiguration functionality monitors sensor health, identifies failed components, and automatically reconfigures the system to optimally integrate the remaining components, thus providing a graceful degradation of performance in the event of a sensor failure. Both the test program approach and the test results are discussed. The testing has given the HINS team a high degree of confidence in the navigation system design and in the software that implements the sensor blending algorithms in the real-time system
