AUTONOMY: PUT TO THE TEST of unmanned systems.
An important advantage ships have over aircraft, is that their radar can see and track other vessels (ARPA) while aircraft cannot. Ship speeds are relative- ly slow, so hazardous situations (usu- ally) develop slowly. Intership and VTS communications are usually by voice over VHF, offering opportunities for misunderstandings due to language pro/ de-? ciencies, accents, dialects etc.
The establishment of communica- tions to be available direct to ships in the area, in an electronic format that can be inputted to the ship’s navigation systems would be a major improve- ment and would be of immediate use by
CAS whether on manned or unmanned vessels. A global standard is needed so shore and ship can interact with each other, otherwise there is the danger that a plethora of incompatible proprietary formats will develop.
