4. NAVIGATION PLANNING Place cursor on desired location ENT: Enter MENU: Escape Figure 4-2 4.1 Entering Waypoints In navigation terminology a waypoint is a particular location on a voyage whether it be a starting, intermediate or destination waypoint. The DD-80 can store 999 waypoints, numbered from 001–999. Waypoints can be registered four ways: • by cursor • by MOB position or event position • at own ship's position, and • through the waypoint list.

Entering waypoints by MOB position/event position Entering waypoints at own ship's position The MOB position or an event position can be registered as a waypoint. Event marks are numbered from 01 to 99; 01 is the latest event mark. Note: When there is no position data, you cannot register a waypoint at own ship's position. The buzzer sounds and the following message appears. Note: You cannot register a MOB position or event position when there are no MOB positions or event positions saved.

10. INTRODUCTION TO GPS 10.2 How the GPS Receiver Calculates Position The basic steps in position fixing are as follows: 10.1 What is GPS? GPS is an acronym meaning Global Positioning System. GPS is a highly precise satellite navigation system developed by the U.S. Department of Defense.
10.3 What is Differential GPS (DGPS)? Differential GPS is based upon accurate knowledge of the accurate geograhical location of a reference station which is used to compute corrections to GPS parameters, error sources and resultant positions. These differential corrections are transmitted to GPS users, who apply the corrections to their received GPS signals or computed position. For civil users, differential corrections can improve navigational accuracy from 100 meters to better than 3 meters.

Glossary Differential GPS (DGPS) Each GPS satellite broadcasts its own orbital data as well as general orbital data of all other GPS satellites. This general orbital data is called the Almanac. The GPS receiver receives the Almanac and decodes it to calculate the quantity and elevation angle of satellites in view, to know when it can receive the GPS signal. If there is no Almanac in the receiver it cannot fix its position.
Magnetic bearing Route Bearing relative to magnetic north, with the compass bearing corrected for deviation. A series of waypoints leading to the ultimate destination. Magnetic variation offset Route navigation The location of the magnetic north pole is different from the geographical north pole. This causes a difference between the true and magnetic north direction. This difference is called magnetic variation, and varies with respect to the observation point on the earth.

INTERFACE UNIT IF-2500 Specifications Input port 2 ports for NMEA 0183 data Output port 6 ports for either of NMEA 0183 or RS-422 data 3 ports for alarm signal Power supply 10 to 35 VDC Power consumption 2.2 W maximum Color 2.5G5/1.5 Newtone no. 5 Ambient temperature -15°C to +55°C Humidity Relative humidity 95% at +40°C Waterproofing None Installation Mounting considersations The installation site is important for proper operation and continued performance.
Cable fabrication 1) Remove the outer sheath, armor, and shield as illustrated. 2) Remove the insulation of cores 3 mm. 3) Cut and solder unused cores to the shield. 4) Solder a ground wire to the shield. 5) Dress the shield and the outer sheath with heat shrink tube, leaving 30 mm of shield and outer sheath exposed. 6) Heat the heat shrink tube. 7) Remove the insulation of NH connector (supplied) 3 mm. 8) Heat the heat shrink tube.
Grounding To prevent electrical shock and mutual interference, run a ground wire between the earth terminal on the unit and ship’s superstructure. Cabling schedules The signal cable should be a twisted-pair, double-screened cable. Ground the signal cable at the cable clamp. Connections Power supply J1 (10 to 35 VDC) Pin no. Designation #1 + #2 – Input signal (NMEA) The signal from DGPS is connected to J2 and J3. Data being fed to J2 has higher priority than J3. J2 J3 Pin no. Designation Pin no.
Output signal (contact closure signal) J10 (WPT alarm) J11 J12 Pin no. Designation Pin no. Designation Pin no. Designation #1 Alarm signal #1 Alarm signal #1 Alarm signal #2 Alarm signal #2 Alarm signal #2 Alarm signal #3 GND #3 GND #3 GND Selection of output data format The output data format is selectable by changing a jumper block; A for RS-422 and B for NMEA. For example, to select NMEA for J4, change the jumper block from A to B on J401 and J402. Do the same on J5 thru J9.
Self test 2 The test requires an external loop to check I/O. Follow the steps below to carry out the test. 1) Set the DIP switch #4 of S1 to the ON position. 2) Temporarily disconnect input and output connectors J2 and J4. 3) Solder a jumper block between J2 and J4; #3 and #4 of J2 are connected to #1 and #2 of J4, respectively. Jumper block consists of XH-6 pin and 4 pin connectors with two short wires as below.

3. ANTENNA UNIT Mounting Install the antenna unit referring to the installation diagram on page D-4. When selecting a mounting location for the antenna unit, keep in mind the following points. • Select a location out of the radar beam. The radar beam will obstruct or prevent reception of the GPS satellite signal. • Be sure the location offers a clean line-of-sight to satellite.
