Attitude Propagation for a Slewing Angular Rate Vector

摘要

A new finding in attitude propagation for a slewing angular rate vector is derived and validated with a known solution. The method employs an additional coordinate system that slews with the angular rate vector. The method can be applied to general attitude propagation and is ideally suited to propagating the attitude in vehicle computer simulations. The method can also be used to propagate the attitude associated with a sequence of angular increments provided by aerospace vehicle inertial navigation units.
