A new navigation aid system having the high accuracy needed in narrow waterways is being developed under the USCG River and Harbor Aid to Navigation System (RIHANS) program. This paper describes the RIHANS approach developed by RCA Corporation, one of the three contractors on this program. A key feature of this approach is that it not only satisfies the RIHANS requirements for ship self-position fixing relative to fixed reference stations but also can easily be expanded to provide functions needed by the associated Vessel Traffic System. These additional functions permit the reference stations to obtain position fixes on all equipped ships, to identify them, and to have two way digital message communication with them. This expanded system is called HATRIC, for Harbor Traffic Ranging, Identification, and Communications.
