On the attitude errors when the quaternionic Wilcox method is used

The paper presents a way to determining the attitude by numerical integration of the Poisson attitude quaternionic equation using a dedicated method suggested by Wilcox. The method is implemented in a Matlab/simulink S-function and simulated with the help of a model for different types of inputs. There is also presented an evaluation of attitude errors for applied inputs and their variation surfaces depending on the time and angular speed.
