Abstract
This paper, after a brief introduction oflMO e-Navigation strategy, highlights that the communication system is the one of the most important components m e-Navigation framework. Through cost-benefit analysis on various types of radio communication used at present, it is proposed that the 500kHz band NAVDAT is one of the best communication solution to e-Navigation strategy. The potential application and perspective of NAVDAT is discussed in this paper with some proposals for recent research.关键词
