  • Page 9: Principle Of The Autopilot

    PRINCIPLE OF THE AUTOPILOT Principle of Autopilot An autopilot is an automatic device for steering a vessel and maintaining its heading in an intended direction. Boat and ship operators can really appreciate the advantages of the autopilot – It steers the boat for you so that you are free to carry out navigational checks, trim adjustments, etc.

  • Page 10: Principle Of Operation

    1. PRINCIPLE OF THE AUTOPILOT Principle of Operation In the AUTO modes, the heading information from a heading sensor is continuously compared with the course that is set on the autopilot’s controller. (in the NAV mode, the course to the waypoint is received from a plotter connected to the NAVpilot-500).

  • Page 17: Steering Modes

    STEERING MODES The NAVpilot-500 system is capable of six primary steering modes: STBY (manual), AUTO, NAV, TURN, REMOTE (FU and NFU) and DODGE. STBY Mode After turning on the power, the equipment goes to the STBY mode. This is a manual steering mode. When sailing into or out of a harbor, steer the vessel in the STBY mode by using the ship’s steering wheel (helm).

  • Page 18: Auto Mode

    3. STEERING MODES AUTO Mode 3.2.1 Using the AUTO mode The NAVpilot-500’s AUTO mode steers the boat automatically on a course set by the operator. Note: The AUTO mode will not compensate for the effects of wind or tide, which can push you off course in the athwart ship direction.

  • Page 19: Advanced Auto Mode

    ADVANCED AUTO mode maintains a set course while compensating for the effects of wind and tide. Note that your NAVpilot-500 must be connected to a (GPS) which outputs own ship’s position data (L/L) in NMEA0183 format to the NAVpilot-500.

  • Page 20: Nav Mode

    3.3.1 Starting the NAV mode If a destination waypoint is set on a GPS / Plotter, the NAVpilot-500 can receive this information and guide the boat to the destination waypoint as determined by the plotter. To use the NAV mode, complete the following steps.

  • Page 21: Selecting Sailing Method Of Nav Mode

    3.3.2 Selecting sailing method of NAV mode When your vessel goes off course while navigating between the origin (previous waypoint) and your current destination waypoint because of a remote control command, etc. the NAV mode uses one of two methods to get back on course: COURSE or XTE.

  • Page 22: Switching Waypoint

    3. STEERING MODES 3.3.3 Switching waypoint When you arrive at a waypoint on a route while in the NAV mode, you can switch to the next waypoint automatically or manually. The AUTO setting will automatically switch to the next destination waypoint when your boat is within the arrival alarm area (set on the plotter).

  • Page 23: Selecting The Boat's Steering Behavior After Arriving At Your Destination Waypoint

    3.3.4 Selecting the boat’s steering behavior after arriving at your destination waypoint The “Fishing mode” can be enabled and set up control your boat’s steering behavior after it reaches the last waypoint in a route. For example, the ORBIT setting will steer the vessel in a circular pattern around the final waypoint (fishing spot).

  • Page 24: Turn Mode

    3. STEERING MODES TURN Mode The [TURN] key provides the various turning motions depending on the mode in use. There are five different turn type; 180º or 360º turns (for AUTO mode only), ORBIT, SPIRAL and FIGURE EIGHT. All turn type are available in clockwise and counterclockwise direction.
  • Page 25 180º TURN (for AUTO mode only) This function changes the current set course by 180º in the opposite direction. After the 180º turn completely, the message “TURN COMPLETED” appears. Return to the AUTO mode by pressing the course control knob. Example of 180º...
  • Page 26 When ORBIT is enabled, your boat will orbit around the boat’s current position. If ORBIT is enabled while in the NAV mode, the boat orbits around the (last) waypoint. This function requires a plotter or GPS be connected. To set parameters for ORBIT, operate the autopilot as shown below.
  • Page 27 5. Rotate the course control knob to select "◄ORBIT" or "ORBIT►", and then press it. The message “START TO TURN BY FISHING MODE” appears, and the boat runs for the distance set at step 3, and then starts making an orbit similar to the figure on the previous page.
  • Page 28 3. STEERING MODES SPIRAL The boat will spiral in the direction of current heading (STBY), set course (AUTO) or the course to the next waypoint (NAV) that was active at the moment that the SPIRAL mode is selected. The radius of the “spiral” can be set in the menu.
  • Page 29 5. Press the [TURN] key to show the TURN menu. 6. Rotate the course control knob to choose “RADIUS OF ORBIT”, and then press it. The current value is circumscribed with a double rectangle. 7. Rotate the course control knob to set the spiral speed. (Setting range: 0.05 to 9.99 nm) 8.

STEERING MODES FIGURE EIGHT After the boat has traveled the distance "d" set on the menu, it starts turning in a figure eight pattern, automatically returning to the position where the figure eight mode was initiated. The “d” is set on menu as RADIUS OF ORBIT. Note: Reduce boat’s speed so that the boat can turn smoothly.
  • Page 31 Navigating to TLL point When TLL (Target Latitude and Longitude) data is input from a radar or echo sounder connected in the STBY, AUTO or NAV mode, the TURN menu appears. Then, you may choose how to progress towards that position, from ORBIT (port direction, starboard direction) or FIGURE EIGHT.

  • Page 32: Remote Mode

    3. STEERING MODES REMOTE Mode Four types of optional remote controllers may be connected to the NAVpilot-500. These are used to operate the Navpilot-500 from a remote location. Dial type remote controller (FAP-5551, 5552) This remote controller can only be used when in the STBY, AUTO or NAV mode. 1.
  • Page 33 The FU is one of auto steering modes, which outputs an absolute value determined with the course control knob to drive the rudder, thus changing the ship’s course at a given rate of change towards a set point.. 2. Rotate the dial on the remote controller to set the rudder angle. The angle must be more than 10°, otherwise no steering will occur.

  • Page 42 4. MENU OPERATION Setting parameters manually When MANUAL-CALM, MODERATE or ROUGH is selected at the previous paragraph, set MANUAL PARAMETER as below. You can set three parameters for MANUAL function: Weather, Rudder gain and Counter rudder. The default manual parameters provide for comfortable steering of a boat 35 feet in length at the speed of 10 kt.
  • Page 43 4. MENU OPERATION WEATHER When the sea is rough, the boat’s heading fluctuates to port and starboard. If the rudder is driven very often to maintain the set course, the helm mechanism may wear out. To prevent this, the weather adjustment makes the NAVpilot-500 insensitive to minute course deviations.
  • Page 44 4. MENU OPERATION Set rudder gain so that the boat does not make frequent yaw. The figure shown below provides general guidelines for setting rudder gain. fast calm light General guidelines for setting rudder gain COUNTER RUDDER If the boat is heavily loaded, the heading could change excessively because of inertia. This phenomenon causes the vessel to “overshoot”...
  • Page 45 Adjusting the sensitivity in monitoring the boat’s trim The NAVpilot-500 continually monitors the boat’s trim in order to keep the trim sensitivity optimum. A lower setting is common because boat’s trim usually does not change quickly. A large number changes the trim compensation value more frequently. Too high a setting may result in the following problems.
  • Page 46 4. MENU OPERATION When towing a net When a boat is in tow of the fishing gear, its stern is “dragged” by the net. This causes the boat to stray from its intended course. To keep the boat on course, you need to adjust the trim manually, which can be bothersome.
  • Page 47 The NAVpilot-500 controls the boat (for ORBIT, SPIRAL function, etc.) by using the speed selected here. When MANUAL is selected and there is a large difference between actual and entered speeds, the boat may not be controlled correctly. We recommend using of GPS speed.
