Navigation requirements of the maritime community

Abstract: There are segments of the maritime community that seem to imply increasingly stringent requirements in respect to radio navigation systems. There is at this time no general consensus of users or user groups for the requirements of a radio navigation system for the high seas. A radio navigation system for use on the high-seas should be adaptable to a high degree of automation such as in a computerized integrated ship conning system. When manually operated it should be simple and quick. In all fairness to the commercial user, he should be supplied with useful synopsis of systems he would be asked to consider in the fulfillment of his requirements. Each synopsis should include information on: general description of the system; coverage, accuracy in various parts of the coverage area; reliability and availability of the system; time required to obtain data; form of output data; capability for integration with other systems; operator skill required; direct or indirect cost to the user.

Economical usage of long range navigation

Abstract: A description of the operation requirements and economic factors which confront the low-cost user of long range navigation/positioning systems serves as an introduction to the comparison of satellite, Omega, Decca, and Loran-C usage in the non-military area. Three categories of users are described--the direct user who desires to know his location, the analytic user who desires a documented record of his unit's track, and the controller who desires the location of other units. The four systems are then compared with respect to those considerations which are of importance from the user's viewpoint. Loran-C is selected as the system which best meets the user requirements. The manner in which Loran-C can be utilized with a description of industrial and governmental tasks concludes the paper.
