G.7. RD-30
Multi-Display
The RD-30 multi-display and data repeater (Figure 3-48) is mounted on the
starboard face of the coxswain’s operating console. The RD-30 utilizes a
wide variety of navigation data and displays it in digital and analog (graphic)
formats. The multi-display uses input from the depth/temperature sensor,
radar, WAAS/DGPS receiver/antenna, and the PG 1000 heading sensor to
provide essential navigational information. The unit features a 4½-inch
backlit LCD and has five user programmable displays. The RD-30 has ten
conditions that can trigger audio and visual alarms:
• Speed
• Water temperature
• Depth
• Arrival/anchor watch
• XTE
• Trip distance (two alarms)
• Countdown timer
• Alarm clock
• No position fixing
• No position data
The RD-30 requires 12-VDC input.
NOTE
G.8. GP-37
WAAS/DGPS
Receiver and
Navigator
The GP-37 WAAS/DGPS receiver and navigator (Figure 3-48) is mounted
on the port face of the coxswain’s operating console. The GP-37 is totally
integrated DGPS receiver and video plotter. The GP-37 can track up to 13
satellites (12 DGPS, 1 WAAS) simultaneously using the WAAS/DGPS
receiver/antenna mounted on the radar pod.
Display modes available are: plotter, NavData (position indication in
latitude, longitude or LORAN), steering (vessel course, position, speed), and
highway. The GP-37 has five available alarm functions and a memory
capacity of 1000 points of vessel track, 999 waypoints or marks, and 50
routes comprised of up to 30 waypoints. The GP-37 has an accuracy of 5
meters or better with DGPS and 3 meters or better with WAAS. The GP-37
requires a 12-VDC power source.
WAAS is not currently approved for use by Coast Guard vessels. In the AUTO mode,
the GP-37 runs with DGPS as the default setting. If the DGPS signal is lost for any
reason, the WAAS mode is automatically selected. Consult the Furuno Operator’s
Manual for the GP-37 DGPS Navigator to enable the AUTO mode from the Menu
selection.
