Information Service (INS)


An Information Service is defined as a VTS that provides essential and timely information to assist the on-board decision making process. This means that VTS operators can inform the master of a vessel about the situation he can expect to encounter within the VTS Area but the VTS may not have the experience to advise on any specific course of action that should be taken. Details about the type of service provided by a VTS can be found in the World VTS Guide.

From a system point of view, the VTS Operator within an Information Service still needs the facilities to monitor the operational situation relating to all maritime activity within the VTS area and still requires facilities to communicate with vessels by VHF radio. Decision Support facilities may not be a necessary part of an Information Service, but the full recording of all activity remains essential and performance measurement should still be a desirable feature.
