Ship Navigation Equipment
Gyro compass
The McARTHUR
II has a Sperry MK227 gyro.
Global Positioning System (GPS)
There are several GPS receivers on
the McARTHUR II. Data outputs from the
GPS receivers are available for scientific use and are continually recorded by
SCS. A networked GPS Time Code Receiver is presently time synching the
shipboard data acquisition system computers. Software is available for time
synching the networked PC-based scientific computers.
Navigation
Navigation software package - Nobeltec's Visual Navigation Suite is the navigation
software package used on the McARTHUR II.
The navigation program is continually run on the bridge while underway and has
the ability to receive location input from the installed GPS receivers.
Traditional paper charts are used as well.
Radar
The McARTHUR
II has two Furuno ARPA Consoles, one X-band and
one S- band with chart overlay. Both radars are used for collision avoidance
and navigation.
AIS
A Furuno
AIS (Automated Identification System) is used to share information about the McARTHUR II with other vessels and vice
versa. This information includes position, speed, course, size, destination,
and CPA (closest point of approach). AIS contacts can be graphically depicted
on the X-band radar scope.
Depth Sounders
Two depth sounders are used for navigation. The Abyss IES-10 Echosounder is used primarily in areas of shallow water. The Simrad ES-60 Fisheries Echosounder can be very effective in deeper water.
Satellite Weather Receiver
A Garmin
satellite receiver displays near real-time meteorological and oceanographic information
in a map format. Displayed information includes atmospheric pressure,
visibility, sea state, swell period, wind speed and direction, and sea surface
temperature.
NAVTEX
The McARTHUR
II has a NAVTEX receiver installed on the bridge. It is used for receiving
and printing the international automated medium frequency (518 kHz) direct-printing
service which provides navigational and meteorological warnings and forecasts,
as well as urgent marine safety information to ships.
Weather Fax
The McARTHUR II has a medium frequency/high frequency, facsimile receiver system for the reception of broadcast weather facsimile pictures and charts. The weather fax is located in the bridge.
