Abstract :
Introduction of Pressure Reference System - Position angles - Based on behavior of ISA - which is used from the beginning of aviation; Measurement results; Integration with AHRS sensors - Zero crossing detection (e.g. zeroing the integration error) has superior influence on the computation - Combination of Zero Crossing and Steady state detection; Adaptively calculates sensor offset error; Lowers error to 1.2°.
