In order to improve the poor accuracy and stability of the traditional geomagnetic matching navigation by TERCOM, In this paper, we discuss a new method which is based on the integration of TERCOM, K-means clustering algorithm and INS (inertial navigation system) in detail. Through an experiment, we find that the new method has higher accuracy and stability than the traditional method, especially...
Inertial navigation system (INS) is an independent navigation system, but is difficult to be used in far-distance and long-time navigation due to INS accumulation error. Thus, a new synthetic navigation system for underwater based on the integration of INS and multibeam bathymetric system (MBS) is studied and presented in the paper. Firstly, we introduce the composition of the underwater navigation...
Based on analyzing current independent navigation methods, this paper presents a new underwater navigation system, which is integrated inertial navigation system (INS) and side scan sonar (SSS). Firstly we introduce the component of the underwater navigation system and the functions of each unit in the system. Then, we study the algorithm of the matching navigation used in the system. A fast image...
