- NAVIONICS Introduces New Micro Chart Module Maritime Reporter, May 1992 #13
One of the world's largest manufacturers of professional natical electronic charts, NAVIONICS, of Woods Hole, has developed a new credit card-size electronic chart module called the NAVIONICS Microchart. The Microchart uses the latest memory card technology and employs "flash memory" devices which consume little power and require no batteries. Several of the world's leading marine electronics equipment companies are utilizing the Microchart in their new product lines.
The Microchart combines a large 128 MB memory storage facility that is the equivalent to hundreds of navigational charts, with the fast data access that is essential to safe navigation.
NAVIONICS electronic charts are now available in either cartridge or Microchart format starting at $150.
The company reports that its seamless database of over 6,000 navigational charts is the largest in the world.
