Abstract

This paper presents a new block diagram for defining a dynamic error in instruments for measuring the angular position of moving objects. The diagram proposes a new concept for investigating dynamic error characteristics as well as for compiling algorithms, inventing methods, and employing means for elimination of the dynamic error as independent component. Based on that concept, a system for measuring the roll, pitch, trim, and heel of moving objects has been developed. The system features high accuracy ensured through a combination of the capacities of different micro-electromechanical sensors that are unified into a shared platform with a specific algorithm used to determine and eliminate a real-time dynamic error. In addition, the paper presents the results from experimental research work. The results confirm the large operational capacity of the proposed concept concerning measurement accuracy.
