AUTOMATIC LORAN NAVIGATOR
Model LC-90 MARK-II
Increases availability of position-fixing capability
by installing Loran-C in addition to GPS
FURUNO DEEPSEA WORLD
The future today with FURUNO's electronics technology
The FURUNO LC-90 MARK-II is a sophisticated
hyperbolic navigation receiver accommodating all
features necessary for safe and efficient navigation. It
covers most Loran-C and Chayka stations in the world,
complying with IMO and US RTCM Loran-C standards.
Carriage of Loran-C and GPS navigators increases the
availability of electronic position-fixing system (EPFS) for
safety and efficiency at sea.
The position is indicated in Lat/Lon without use of the
Loran charts or tables. TDs from preselected master-
secondary stations can be indicated. The display reads
major system data. Various navigation data and
parameters are marked with an index cursor.
Parameters include cross-track error, waypoint numbers,
time-to-go, speed and course. Up to 100 waypoints can
be entered by Lat/Lon, TD, or range and bearing from
any position. Current Lat/Lon and TDs can be instantly
stored as an event position by pressing the SAVE key (20
max). The stored event position may be recalled at any
time and easily registered as a waypoint for permanent
storage.
The LC-90 MARK-II automatically select the optimum
master and secondaries, compensates for ASF for
improved accuracy over a varying terrain and time of day.
Automatic functions may be manually overridden by the
operator.
