Chapter 1 General Information

1.1 About GPS

1.1.1 General

GPS is a navigation system using 24 satellites (21 plus 3 in service) orbiting 20,183 km high from the
earth every 11 hours 58 minutes.

1.1.2 Positioning by GPS

Your position is determined by calculating the distance from two satellites (in 2-dimensional p ositioning)
or three satellites (in 3-dimensional positioning) to your position. The distance is determined by the time
taken for a message to be sent from the satellites to the receiver. In 2-dimensional positioning, your
position (latitude and longitude; height is preset) is determined at the intersection point of three spheres
formed by three satellites. In 3-dimensional positioning, your position (latitude, longitude and height) is
determined at the intersection point of four spheres formed by four satellites.

1.1.3 Time required for position fix

In the following circumstances, your GPS receiver takes more time to fix position:
(1) When you turned the GPS receiver for the first time.
(2) The stored orbital data is not suitable for the available satellite, or purged due to lengthy storage.
(3) When you use it after moving a long distance

The GPS receiver first turned on starts to store the orbital dat a sent from the sat ellite. It takes about 2 o r
3 minutes before the first fix is available. After this, the receiver can fix your position within a minute by
using the previously stored data.

NOTE

The GPS system is based on a geodetic system called WGS-84. In conventional world map, one
coordinate system differs from others with region, and this cause s the position fix made on the m ap
and GPS measurement to differ to a certain extent.

(DATA port)
This port is general data output port. Output data is selected by the menu among the output of

IEC 61 162-1,NMEA Ver.1.5, CIF, and SHIPMATE. Output signal level is RS-422.

(DATA 2 port)
When CW-376/391 are used.

This port is data input/output port for DGPS beacon receiver. If a DGPS receiver is not connected,

it can be used as a data output port for extension, but unlike the DATA port, output is possibl e only
for IEC 61 162-1. Output signal level is RS-422.

When CW-398 are used.
This port is an only for external alarm system. ACK/ALR output signal level is RS-422,and EXT

BUZZER out put can drive a relay(24V/10mA). BUZZER STP is an input port for stopping a buzzer,
and impresses 24V.

4.9 Inspection after installation

Before you turn the unit on, check the following points to make sure the system operate s prope rly.
(1) Is the ship’s supply voltage and current within the rated ra nge?
(2) Is the connection between the display and antenna unit correct?
(3) Are the cables routed a nd connected properly?

NOTE: ACK/ALR of menu 9-3 needs to be turned off. See chapter 8.6.5 (page 8-19)

8.4.4 Compensating the compass Initial setup: Auto mode

The course and bearing to waypoint is shown in true bearing. You can adjust the GPS true bearing to
the magnetic compass bearing.

(Automatic compensation)

In the Auto mode, the magnetic compass is compensated based on the built-in global magnetic
variation maps. However, avoid using this mode if you are higher than 75 degrees North or South
latitude. As the compass may have a small error because the system contains world maps. Manual
correction is recommended. For areas that do not allow exact translation of a true bearing to a
magnetic bearing, despite the map covering the whole world, the resulting value may differ from the
actual deviation.
