AIS Aids to Navigation

Section 1. Background

(Additional information about the AIS can be found on the Automatic Identification on Ships web page)

The introduction of AIS aids to navigation (AIS AtoN) makes it possible to display more details on navigation equipment than ever before, as well as information that a lookout may not be able to detect.

The provision of information in a digital format adds to traditional navigation instruments and provides mariners with new tools in their decision-making process. In situations (such as a new reef or detected shoal) where the deployment of physical aids to navigation is not possible and other means of communication are restricted, broadcasting virtual AIS aids to navigation (and related navigation warnings) may be the only feasible solution for providing critical information. Accordingly, mariners may need to base some decisions primarily on virtually displayed information. Since this technology introduces navigation techniques outside of the standards for training that mariners receive, they needed to acquire a sufficient level of confidence in the technology. To accomplish this, the Canadian Coast Guard (CCG) provided supervised test beds involving three types of AIS AtoN. While the AIS AtoN service becomes fully operational, some testing may continue as the technology evolves.
