Detection Technology of Roll Attitude Based on Geomagnetic Signals and Inertial Trajectory Study

Abstract:

The intensity and direction of the geomagnetism vector is a function of geography position. The roll attitude of flying ammunition can be calculated by detecting geomagnetism. In the paper, the chief scheme and implement method of roll attitude detection system are suggested. The result of the geomagnetic detection unit can be used to resolve attitude by inertial trajectory. After experiments on 2-axis turntable are implemented, the results show that by the geomagnetic solution the angle error is of no cumulative characteristics, and the absolute error at different rotating speeds are controlled within 2 deg.
