Abstract: Recommendation 493 of the XIVth Plenary Assembly of the International Radio Consultative Committee (CCIR) formally adopted the digital selective calling system (SELCALL) for mobile marine communications. The SELCALL system, which represents more than a decade of work by the international marine telecommunications community, provides a reliable automated means for selective ship/shore contact in the MF, HF and VHF marine radio bands. Work is proceeding, particularly in the MF and HF bands to develop the procedures and equipment needed to implement SELCALL contacting on a global basis This paper treats the related and equally important area of SELCALL applications, particularly at VHF. SELCALL is, fist and foremost, a digital contacting system but because of its development to serve the diverse needs of a multinational maritime community, it can provide a very versatile means for both telecontrol and telecommunication service. The implications of this capability to serve marine communications and navigation in the more densely populated coastal waters, rivers and ports are only now beginning to be appreciated. A description of the SELCALL message structure and spectrum requirements for use at VHF/UHF is given in this paper together with several important applications to marine communications, navigation and traffic management.
