Abstract:	This paper examines relation between motion and response of attitude heading reference systems (AHRS) aided by global navigation satellite systems (GNSS) in the loosely-coupled style. In order to analyze which motion affects outputs of the system, both flight experiment and simulation based approaches are conducted. The results of this study are that motion in which acceleration and angular speed change nonstationarily helps greatly to decrease error in the systems. According to these results, as a guideline, DO-334 recommended trajectories, which are originally intended for use of AHRS tests, are still effective for evaluation of GNSS aided AHRS.
