USS Ralph Johnson Navigation Common Core:  Navigation 106.1 Officer of the Deck: Direct representative of the Commanding Officer for the safe navigation and general operation of the ship. Conning Officer: Directs the movement of the ship by giving orders to the Helm/Lee Helm. BMOW: Maintains the daily routine of the ship. Responsible for the manning, routine, behavior, and appearance of the watch. Responsible to the OOD. Helm/Lee Helm: Helm controls the ship’s course. Lee Helm controls the ship’s speed. Lookouts: Provide visual/audible watch for all surface, subsurface, and air contacts to CIC. QMOW: Direct representative of the Navigator. Responsible for the safe navigation of the ship, and  Navigation 106.2 Latitude: Measurement in degrees of arc from 0 to 90, either North or South from the Equator. Longitude: Measurement in degrees of arc from 0 to 180, either East or West of the Greenwich meridian. Set: is the direction the ship is moving, measured from DR to fix. Drift: is the speed the ship is moving, measured from DR to fix. GMT/ Universal Standard Time: GMT (Greenwich Mean Time) is the local time of the sun’s meridian passage at Greenwich, England. Universal Standard Time: is based on the Earth’s rotation (24hrs). Time Zones: Measured from East and West of Greenwich, England in 15 degrees increments for a total of 24 time zones. Variation: Angular distance measured from Magnetic  Navigation 106.2-106.4 IALA A Buoyage System: has red buoys on the STBD side as the Ship is leaving port. IALA B Buoyage System: Red buoys on the STBD side as the Ship is entering port (RED RIGHT RETURNING). Cardinal System: The relation of compass direction to basic cardinal directions. North-000, East-090, South- 180, West-270. Different methods of Determining the Ship’s Position: Visually, Radar Lines, Soundings, Electronic, Celestial. Describe the Purpose of Range/Channel Markings: Used to visually determine whether the Ship is right or left of Track.  Navigation 106.5 Advance: The distance gained in the direction of the original course until the ship steadies on her final course. Transfer: The distance gained at right angles to the direction of the original course until the ship steadies on her final course. Pivot Point: The center of rotation as the ship alters course. On DDG-114 located just behind the helm. Acceleration/ Deceleration: The rate at which the ship speeds up, or slows down, after an engine order. Speed and momentum are critical and must be calculated during station keeping, anchoring or mooring. Turning Circle (Final Diameter): The diameter of the circle traversed by a vessel after turning through 360 degrees while maintaining the same speed and rudder angle.  Navigation 106.6 True Bearing: Direction measured from 000-359 degrees in relation to True North. Relative Bearing: Direction measured from 000-359 degrees in relation to Ship’s heading. DIW (Dead in Water): Also known as “crippled ship.” When a vessel is unable to move or function; inoperable. Head On: Two power driven vessels on reciprocal courses at risk of collision. Crossing: Two power driven vessels crossing, resulting in possible collision. Overtaking: When one vessel passes another vessel. Giveway Vessel: Vessel must take action to avoid  Navigation 106.7 Collision: Two vessels striking each other. Aground: Vessel on or onto the bottom of shallow water.  Navigation 106.8 Stadimeter: Optical Sextant: Optical instrument for instrument for Measuring determining the distance the angular distance of of an object with a celestial objects from the KNOWN height. horizon. Binoculars: Optical instrument for viewing Bearing Circle: A ring distant objects. designed to fit on a compass to provide Telescopic Alidade: Optical bearings. instrument that fits on a compass to determine bearing of distant objects. Azimuth Circle: A ring designed to fit on a compass with a mirror and prism to take bearings to celestial objects (Sun).  Navigation 106.8 Chart: Map that shows the configuration of the shoreline and sea floor. Magnetic Compass: DFGMC. Type of magnetometer that senses magnetic field changes around two electrified coils. Delivers near-perfect Gyrocompass: Electronic compass which magnetic heading. constantly seeks and displays true north. Also provides pitch, roll, position, time, velocities, and altitude rates.  Navigation 106.8 RADAR: Stands for Radio Detection and Ranging. For navigation, can be used to locate navigational aids and perform radar navigation, but also track other vessels in order to avoid collision. Fathometer: Type of echo sounder used to determine water depth in either feet or fathoms. Global Positioning System (GPS): Satellite system used to determine position. 26 satellites total, only 4 used at any given time. Three for position, one for altitude. Laser Range Finder: Uses a laser beam to determine distance. Integrated Bridge System: Combination of systems, which are interconnected to allow monitoring of various NAV systems.  Navigation 106.9 Underway: Mast Light, Port/STBD Running Lights, Stern Light In-Port, Moored: Air Craft Warning Lights, Anchor Lights, Waterline Lights, Deck Lights Engaged in Special Operations: Restricted Maneuvering Lights (Red-White-Red). Man Overboard: Red over Red-Blinking, Port/STBD Running Lights, Stern Light Not Under Command: Red over Red- Steady, Port/STBD Running Lights, Stern Light Anchored: Same as Inport, Moored. Aground: Red over Red- Steady, Deck Lights, all around white lights Fore and Aft. Towing: Underway Lights + 2 Mast Lights, or 3 Mast Lights for Vessels over 200 meters.  Navigation 106.10 Vessel at Anchor: One Ball Vessel Not Under Command: Ball over Ball Restricted Maneuvering: Ball, Diamond, Ball Vessel Aground: Ball, Ball, Ball Constrained by Draft: Cylinder Towing: One Diamond  Navigation 106.11 Personnel Recall Boat Recall Divers Refueling/ SOPA Ammunition Aloft/ Over the Side HERO Cond.

Absence of embarked Chief of Staff or Chief Staff Officer. Displayed on PORT yardarm (inboard). Absence of Commanding Officer for a period of 72 hours or more. Displayed on PORT yardarm (outboard).  Navigation 106.12 Low Visibility Sound Signals: Underway- One Prolonged Blast every 2 minutes. Anchored- Rapid ringing of bell from the forecastle for 5 seconds every 1 minute. Vessels Anchored >100 meters- Rapid ringing of bell from the forecastle for 5 seconds, and a rapid ringing of the ship’s gong for 5 seconds aft every 1 minute.  Navigation 106.14 Barometer: Measures atmospheric pressure in inches of mercury. Predicts bad weather. Psychrometer: Aerographer tool that measures air temperature and dew point. Predicts fog. Communication Circuits: Allows the relay of pertinent navigation information to the Bridge and CIC. Telltale Panel: Energize navigation lights, and indicates if a light is out. Steady light indicates primary filament is out, buzzing means both filaments are out.  Navigation 106.15 Voyage Management System (VMS): Electronic charting system that continuously updates the ships position on a digital charting display. Is part of the Integrated Bridge System (IBS). Accepts inputs from all relevant sources; Fathometer, GPS, Wind birds, INS, Gyros, etc.  Navigation 106.16 Guide Ship: Controls when to execute events for ships in formation.
