S-201 Product Specification

The S-201 Aids to Navigation (AtoN) Information Product  Specification provides a common structure  for the exchange of information about AtoNs. This includes buoys, beacons, racons, lights, sound signals and AIS. The product  contains the positions, properties, operational status and general comments related to an AtoN.

The S-201 PS can be used to exchange AtoN information in a consistent  form between Lighthouse Authorities, Hydrographic Offices and other organizations, including commercial and professional agencies.

The draft version of S-201 is attached below.

Please note that the Product Specification includes zip files, containing potentially executable code (xml). Every effort has been made to ensure that this does not present a cyber security risk. However files are opened and used at your own risk.

It should also be noted that this code is not finalised and no attempt should be made to run it.
