3. Minimum range
30* m on 0.75 nm range scale
*Using a 10 m
2 test target at 3.5 m high above sea and
antenna at 15 m high (IEC 60936-1). Different conditions give
a different result, maybe close to 20 m in actual installations.
4. Range discrimination
30 m on 0.75* nm range scale
5. Range ring accuracy
+0.2 %
6. Presentation modes
Head-Up, Course-Up, North-Up, North-Up TM
7. Heading information
Furuno GPS compass SC-60/120 is a recommendable
heading sensor as a backup of a gyrocompass. Confirm with
your Administrations.
8. Parallel index lines
1, 2, 3 or 6 lines (menu selectable)
9. Radar map
1500 points to create coastlines, own ship safety contour,
isolated underwater dangers, buoys, traffic routing systems,
prohibited areas, fairways as required by IMO.
Automatic Plotting
1. Acquisition
100 targets (e.g. manually 50, automatically 50)
2. Tracking
Automatic tracking of all acquired targets in 0.1 to 32 nm
3. Guard zone (Target Acquisition Area)
Two guard zone, one of them 0.5 nm depth
4. Vector
True or relative 30 s, 1, 3, 6, 12, 15, 30 min for prediction of
target motion
5. Past positions
5 or 10 past positions at intervals of 30 s,1, 2, 3, 6 min.
6. Collision warning
CPA limit: 0.2 - 10 nm, TCPA limit: 0 - 99 min.
7. Trial maneuver
Dynamic or static, with selected delay time.
