The bulk of the world's commodities essential to the needs of expanding populations is carried by the maritime industry. At present in the field of navigation a variety of terrestrial electronic aids contribute to satisfactory basic operational requirements, but the several radio systems of communication for ships are becoming increasingly overloaded and presenting problems, particularly in the sphere of distress, search and rescue work. The only relief of this pressure is by the employment of satellite communication which can provide global coverage, high quality ship shore links with little or no delay for voice, machine telegraphy, or data. Satellite systems appear to be capable of handling economically even the present traffic growth, so any further expansion makes these systems even more attractive. Furthermore, navigational can be provided to supplement existing aids and help meet new requirements such as routing and collision avoidance.
