OVERVIEW: Aids to Navigation Program

Qualified Auxiliarists and their facilities are authorized assignment to duty to support and augment the Coast Guard’s Aids to Navigation program. This includes verifying the location and characteristics of private aids to navigation (PATONs), after qualifying as an AV – Aid Verifier. Auxiliarists may assist and support Coast Guard units in servicing Federal aids after receiving proper Coast Guard training. Auxiliarists may also help the National Oceanic and Atmospheric Administration (NOAA) and the US Army Corps of Engineers in updating nautical charts and publications. Training is available in all four Auxiliary Navigation Systems Programs – ATONs, PATONs, Bridges, and Chart Updating.
