The International Maritime Organisation (IMO) is developing e-Navigation as the future approach to marine navigation in order to enhance maritime safety. As such, the IMO state that positioning systems for e-Navigation “should be resilient …. robust, reliable and dependable. Requirements for redundancy, particularly in relation to position fixing systems should be considered”
