Estimated ship arrival time service

Automatic Identification System
AIS is an automated tracking system used on ships for identifying and locating other vessels and is used in navigation primarily for collision avoidance. The AIS transponders automatically broadcast information, such as their position, speed and heading, at regular intervals via a VHF transmitter built into the transponder. Shipboard AIS transponders have a horizontal range that is highly variable but typically only about 35 nautical miles (NM). However, the signal has a vertical range over 200 NM, and over the past few years polar orbiting satellites have been launched that can pick up these signals. Now, with the launch of these satellites, AIS tracking is possible globally.

Constantly track vessels and their ETA
Not every vessel has the need for speed and consumption performance reports. For these vessels, ETA Monitoring Service (EMS) can provide a valuable tracking service—an indispensable tool for keeping track of a vessel’s location and monitoring its Estimated Time of Arrival (ETA). The vessel’s ETA is continuously updated throughout the voyage as new weather or position data is received. These vessels are also included in the EMS Daily Fleet Status report so you can quickly see if the vessel is falling behind schedule or encountering bad weather. This service is developed in collaboration with InterTranIS.
