3.6 Entering the MOB Mark 2) Press the [NU/CU ENT] key. If the display in use is Highway, Navigation or Data, they are automatically replaced by the Plotter 2 display. The MOB mark denotes man overboard position. To mark man overboard position, press the [EVENT MOB] key. When the key is pressed, the position at the exact moment the key is pressed automatically becomes the destination. Further, the Plotter 1 display replaces the display in use when it is other than a plotter display.
4. NAVIGATION PLANNING 4.1 Registering Waypoints In navigation terminology a waypoint is a particular location on a voyage whether it be a starting, intermediate or destination waypoint. The GP-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. Registering waypoints by the cursor 1) Press the [WPT RTE] key. The Waypoint/ Route menu appears. Waypoint/Route 1.
6) Press ▼ to select waypoint mark shape. The following display appears. : Cursor ENT: Enter MENU: Escape Figure 4-4 Screen for selecting waypoint mark shape Control is returned to the last used display mode. When the waypoint number entered at step 5 already exists, the message shown in Figure 4-4 appears if the waypoint is part of the current destination or route or is part of a route. If it is alright to write over the waypoint and its data, press the [Y] key.
Registering waypoints by MOB position/event position Registering waypoints by 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.
4.2 Editing Waypoints Edit = Waypoint : 001 _ _° _ _._ _ _' N _ _ _°_ _._ _ _' W 1) Press [WPT RTE] and [4].

4.3 Deleting Waypoints 4.4 Registering Routes Deleting waypoints by the cursor Often a trip from one place to another involves several course changes, requiring a series of route points which you navigate to, one after another. The sequence of waypoints leading to the ultimate destination is called a route. The GP-80 can automatically advance to the next waypoint on a route, so you do not have to change the destination waypoint repeatedly. 1) Place the cursor on the waypoint to delete.

5. STARTING FOR DESTINATION 5.1 Setting Destination There are four ways by which you can set destination: • By cursor • By MOB position or event position • By waypoint, and • By route. Note 1: Destination cannot be set when there is no GPS position data. When there is no position data, the buzzer sounds and the message shown in Figure 5-1 appears. Setting destination by cursor Using the cursor you may set a destination consisting of 30 points.

Waypoints are connected with a line. 5) Press the [NU/CU ENT] key to finish. The route number entry display appears as shown in Figure 5-5.
Setting destination by MOB position or event position Setting destination through waypoint list Note: This operation cannot be performed when there is no MOB position or event position. The buzzer sounds and the message shown in Figure 5-8 appears to alert you when there is no MOB position or event position. Note: A waypoint must exist to set it as destination. When a waypoint does not exist, the buzzer sounds and the message shown in Figure 5-10 appears.

Skipping route waypoints You may skip route waypoints by displaying "DI" (DIsable) next to the route waypoint in the route list. Using Figure 5-14 as an example, your ship is currently heading toward waypoint 04 but is to switch course and head to waypoint 03. In this case you would want to skip waypoint 04. ,, ,, ,, ,, ,,, ,,, ,,, ,,, Waypoint 03 Waypoint 04 5) Press the [NU/CU ENT] key. 5.2 Cancelling Destination 1) Press the [GOTO] key. Waypoint 05 2) Press [5] to select Cancel.
5.3 Erasing Route Waypoints (flags) 1) Place the cursor on the flag to erase. 2) Press the [CLEAR] key. The message shown in Figure 5-17 appears if the waypoint is currently selected as destination, is part of a registered route, or is part of the route currently being navigated. 1st line Are you sure to erase ? ENT:Yes MENU:No When flags are erased When the origin waypoint is erased the waypoint before it becomes the origin waypoint.
5.4 Finding Range and Bearing Between Two Points Selecting Course Sailing Method The range and bearing to a destination are calculated by two ways: Great Circle or Rhumb Line. However, cross track error is calculated by rhumb line only. Great Circle: The great circle courseline is the shortest course between two points on the surface of the earth. (Imagine stretching a piece of yarn between two points on the earth.) However, this course requires frequent change of heading to follow course faithfully.
3) Press ▼ to shift the cursor to the Trial Speed line. 4) Press t or s to select Auto or Man. Auto uses ship's average speed to calculate time-to-go. 5) If you selected Man, enter speed. 6) Press the [NU/CU ENT] key. The range, bearing and time-to-go between two points appear on the display. If data entered is wrong or insufficient the buzzer sounds and the message "INCOMPLETE DATA" appears. If the data contains error, "*" and all nines appear as the calculation results. 7) Press the [MENU ESC] key.

10.2 How the GPS Receiver Calculates Position 10. INTRODUCTION TO GPS The GPS receiver’s position is continuously fixed by receiving 3 (or 4) satellites in lineof-sight of the GPS receiver. The basic steps in position fixing are as below. 10.1 What is GPS? 1) GPS satellites continually transmit their own precise orbital data called ephemeris. The GPS receiver computes satellites’ position by this data. GPS is an acronym meaning Global Positioning System.
10.3 Position-fixing Accuracy (HDOP) In radar position-fixing, most accurate position fixes are obtained when the targets used are spaced nearly 90° from each other. Similarly, GPS position fixing accuracy is subject to satellite location. Generally, the further apart the satellites are from one another, the greater the position-fixing accuracy. For example, take a look at Figure 10-2. In both situations a fix is obtainable in the Northern Pacific region because three satellites are in line-of-sight.

Glossary Almanac 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.
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.
True bearing Bearing relative to North; compass bearing corrected for magnetic deviation. The GPS receiver can display true or magnetic bearing. Velocity to destination The amount of speed in the direction (course) of the desired destination. Waypoint A waypoint is a particular location on a voyage whether it be a starting, intermediate or destination waypoint.
