In many cases a trip from one place to another involves several course changes, requiring a series of waypoints which you navigate to, one after another. The sequence of waypoints leading to the ultimate destination is called a route. Your unit can automatically advance to the next waypoint on a route, so you do not have to change the destination waypoint repeatedly.

4.1 Creating a Route

You can store up to 50 routes (numbered 01 to 50) and one LOG route, and each route may contain up to 30 waypoints. A route may be constructed four ways: by the cursor, through the waypoints list, current position (track-based route) and through the route menu.

Note: Be sure to record all important routes in a separate log. This unit is not a fail-safe record keeping device.

4. ROUTES

Figure 4-2 Waypoint name entry window

GPS SETUP menu description

SMOOTH POS (Smoothing position)

When the DOP (Dilution of Precision, the index for position-fixing accuracy) or receiving condition is unfavorable, the GPS fix may change greatly, even if the vessel is dead in water. This change can be reduced by smoothing the raw GPS fixes. The setting range is from 0 (no smoothing) to 999 seconds. The higher the setting the more smoothed the raw data, however too high a setting slows response time to change in latitude and longitude. This is especially noticeable at high ship’s speeds. “0” is the normal setting; increase the setting if the GPS fix changes greatly.

SMOOTH S/C (Smoothing speed/ course)

During position fixing, ship’s velocity (speed and course) is directly measured by receiving GPS satellite signals. The raw velocity data may changes randomly depending on receiving conditions and other factors. You can reduce this random variation by increasing the smoothing. Like with latitude and longitude smoothing, the higher the speed and course smoothing the more smoothed the raw data. If the setting is too high, however, the response to speed and course change slows. The setting range is from 0 (no smoothing) to 999 seconds.

AVR. SPEED (Speed averaging)

Calculation of ETA and TTG, etc. is based on average ship's speed over a given period. If the period is too long or too short calculation error will result. Change this setting if calculation error occurs. The default setting is one minute. The setting range is from 0 (no averaging) to 99 minutes.

LAT/LON OFFSET (L/L position offset)

You may apply an offset to latitude and longitude position generated by the GPS receiver, to increase position accuracy.

DISABLE SV (Disable satellite)

Every GPS satellite is broadcasting abnormal satellite number(s) in its Almanac, which contains general orbital data about all GPS satellites. Using this information, the GPS receiver automatically eliminates any malfunctioning satellite from the GPS satellite schedule. However, the Almanac sometimes may not contain this information. You can disable an inoperative satellite manually. Enter satellite number in two digits and press the [ENT] key. To restore a satellite enter “00”.

FIX MODE

Selects position fixing method; 2D or 2/3D. 2D requires three satellites in view of the GPS receiver; 2/3D requires three or four satellites in view of the GPS receiver, whichever is available. When the 2D mode is selected, enter the antenna height above the waterline, to obtain accurate position data. The default setting is 5 m. The table provides common feet equivalents.

9. INSTALLATION

9.1 Installation of Display Unit

Mounting considerations

The display unit can be installed on a tabletop, on the overhead, or in a panel (optional flush mounting kit required). Refer to the outline drawings at the end of this manual for installation instructions. When selecting a mounting location, keep in mind the following points:

• Locate the unit away from exhaust pipes and vents.

• The mounting location should be well ventilated.

• Mount the unit where shock and vibration are minimal.

• Locate the unit away from equipment which generates electromagnetic fields such as a motor or generator.

• Allow sufficient maintenance space at the sides and rear of the unit and leave sufficient slack in cables, to facilitate maintenance and servicing.

• Observe the following compass safe distances to prevent deviation of a magnetic compass. Standard compass, 0.5 m, Steering compass, 0.3 m.

Tabletop and overhead mounting

9.2 Installation of Antenna Unit

Mounting considerations

Install the antenna unit referring to the antenna installation diagram at the end of this manual. When selecting a mounting location for the antenna unit, keep in mind the following points:

• Do not shorten the antenna cable.

• Select a location out of the radar beam. The radar beam will obstruct or prevent reception of the GPS signal.

•

The location should be well away from a VHF/UHF antenna. A GPS receiver is interfered by a harmonic wave of a VHF/ UHF antenna.

• There should be no interfering object within the line-of-sight to the satellites. Objects within line-of-sight to a satellite, for example, a mast, may block reception or prolong acquisition time.

• Mount the antenna unit as high as possible. Mounting the antenna unit as high as possible keeps it free of interfering objects and water spray, which can interrupt reception of GPS satellite signal if the water freezes.

• The length of the whip antenna for the GPA-018 (for GP-36) should be no longer than 1.2 meter to prevent antenna damage. Do not use a 2.5 meter whip

antenna.

Flush mounting

There are two types of flush mounting kits. For details, see the outline drawings at the end of this manual for details.

• If the antenna cable is to be passed through a hole which is not large enough to pass the connector, you may unfasten the connector with a needle nose pliers and 3/8-inch open-end wrench. Refasten it as shown in Figure 9-2, after running the cable through the hole.

CAUTION

Ground the equipment to prevent mutual interference.

Figure 9-3 Wiring

Note: The fuse holder contains a spring which fixes the fuse. T o prevent detachment of the spring, which would cause loss of power, tie the line as shown in Figure 9-4.

Fuse holder

+ line (red)

The display unit contains a CPU. While it is operating, it radiates noise, which can interfere with radio equipment. Ground the unit as follows to prevent interference:

• The ground wire should be 1.25sq or larger.

• The ground wire should be as short as possible.

• The signal ground and frame ground are separated, however the power line is not isolated. Therefore, do not connect the signal ground to the frame ground when connecting other equipment to a positive ground battery.

• The antenna unit GPA-018 (for GP-36) must be grounded. Connect a ground wire of 1.25sq or larger (local supply) between the ground terminal on the antenna unit and a stainless steel screw fastened to the mast. Coat the ground terminal, stainless steel screw and crimpon lug on the ground wire with silicone sealant.

• The power of this equipment is not isolated, thus the earth lamp may light when the antenna unit GPA-018 is grounded. If it lights, attach two capacitors (1mF,

0.1mF) in parallel to the antenna earth line.

External equipment

The power supply port is commonly used for connection of external equipment such as navigation equipment or a PC. Refer to the interconnection diagram on page S-1 or S-2 for connection.

Tie here.
