AbstractTheU.S. Navy, through a contract with MYSTECH ASSOCIATES, INC., has developed an advanced proto‐type navigational system called MATCH‐NAV, which utilizes a mini‐computer to provide automated own‐ship geographic position in inshore, coastal navigation situations. Conceptual development of MATCH‐NAV has demonstrated the capability to provide ownship position display on digitized nautical charts, with overlay of the chart data on a radar Plan Position Indicator (PPI). Future plans include utilization of the MATCH‐NAV concept in design of a completely automated Ownship Position Display having stored nautical chart capability, which can accept navigational data inputs from such ship's sensors as Loran‐C, Omega, radar and other precision electronic navigation systems, including satelite systems. The goal—to provide continuous, accurate, real‐time visual display of ship's position in restricted coastal waters.This paper discusses the MATCH‐NAV concept and its potential applications in future
