Strap down die gyro device

摘要

PURPOSE: To output azimuth-attitude angle signals based on actual azimuth- attitude angle fluctuation without being influenced by the arithmetic speed limit of a strap-down arithmetic part in a strap-down type gyro device. ;CONSTITUTION: An interpolation arithmetic part 6 is provided on the output side of a strap-down arithmetic part 3 so as to compute predictive azimuth- attitude angle signals predicted at the output time instant. The strap-down arithmetic part 3 is of either a system using a low-pass filter 62 or a system using an α-β filter 65.;COPYRIGHT: (C)1993,JPO&Japio
