10/2/2003, 1:41:03 PM
The Options on the Map Page allow you to customize the page in several ways although not all options are visible all the time. The following options are always available: Clear Track Log: Allows you to clear the track log and immediately start a new one. Measure Distance: Allows you to choose two way (the default for one is your current position) and then select a second waypoint. The distance, estimated time needed to reach that point, and your current estimated speed is calculated automatically. Map Setup: Allows you to adjust the map settings including: Orient Map (Ahead or Northward): When AHEAD is selected, the top of the map is oriented in the direction you are currently moving. When NORTHWARD is selected, the map is always oriented to the North. Auto Zoom (On or Off): When AUTO ZOOM is turned on, the map automatically adjusts its scale to display your entire navigating route until you manually change the zoom level. When its turned off, you must press the UP or DOWN Button to select the appropriate map scale. Waypoints (Show or Hide): Allows you to view the map with or without waypoints. Goto Line (Bearing or Course): Determines whether the display pointer shows your current bearing or the direction to the next waypoint. Options that do not display until you have a track log or are actively navigating include: Pan Track Log: Allows you to move the pointer to any point along the track and then start a TRACBACK, a GOTO, MARK a waypoint, or ZOOM In or Out. Stop Navigation: STOP NAVIGATION stops any active navigation (navigation means there is a destination waypoint).

Map Page Options

Selecting PAN TRACK LOG from the Map Page options allows you to move the pointer to any point on the track log and then create a Waypoint or navigate to it.
When you select Orient Map Northward the gure icon is replaced by a direction triangle. The tip of the triangle tells you the general direction in which you are moving.

190-00297-01_0C.indd 5

Using the Track Log
The Geko 201 draws an electronic breadcrumb trail or track log on the Map Page as you travel. The track log starts recording as soon as the Geko 201 gets a location x. To make use of the track log, select the PAN TRACK LOG option to show a pointer which moves along the track log when you press the UP or DOWN Button. Press the OK Button to see the four choices TRACBACK, GOTO, MARK and ZOOM.
CLEAR the track log before starting a new trip.
TracBack will guide you to where you started by following the track log that you left behind, allowing you to return along a traveled path without marking any waypoints. For the best results, clear the track log before you start traveling because when the track log is full, the new track points will overwrite the oldest track points. Goto guides you from your current location to the waypoint selected while Mark creates a new waypoint for later use. Mark is explained in detail beginning on Page 11. Zoom adjusts the level of viewable map detail.

To clear the track log:

1. From the Map Page, press the OK Button to display the Map Page Options menu. 2. Press the UP or DOWN Button to highlight CLEAR TRACK LOG and press the OK Button. 3. At the message DO YOU REALLY WANT TO CLEAR THE TRACK LOG?, use the DOWN Button to highlight YES and press the OK Button to clear the track log and return to the Map Page.

Tracks

As discussed on Page 6, the Geko 201 draws an electronic breadcrumb trail or track log on the Map Page as you travel. The track log starts recording as soon as the Geko 201 gets a location x. If you want to keep a record of a certain track log before deleting it, go ahead and save it. You can save a total of 10 tracks in the Geko 201. Saved tracks can be used for navigation later. After a track log is saved, the saved track will have a beginning (BEGIN) and ending (END) point. This simply shows the when/where of the starting and ending points of the saved track. When you are ready to return to where you started, the Geko 201 will take you back by following the track log that you left behind. TracBack allows you to return along a traveled path without marking any waypoints. If you want to keep a record of a certain track log or use the TracBack feature, it is recommended that you clear the track log before you start traveling. The percentage of memory used by the current track log is displayed at the top of the page. After the track log is CLEARED, it will show zero percent. When the display shows 99%, the most recent track points will start overwriting the earliest track points. Thus, in order to avoid losing any track points, you should save the track log before it reaches 99% of memory usage.

10/2/2003, 1:41:13 PM
The Geko 201 allows you to navigate using one of three methods: Goto, TracBack and Route. The Goto method of navigation was briey discussed on page 6 and TracBack is discussed on page 18. A route is at least two waypoints that describe the path you are going to travel. The route feature is very convenient because it allows the Geko 201 to guide you from the rst waypoint in the route, to each successive waypoint until you reach your nal destination. The route feature and the Goto feature are comparable in that they both guide you to destination waypoints. However, the route feature is more powerful because it is more automatic. When you reach one waypoint, the Geko 201 automatically guides you to the next waypoint on the route without needing to touch any button. When you use the Goto feature you have to stop and select the next waypoint before you start moving. When you plan a trip, you can select waypoints from a waypoint list and put them into the Geko 201s memory. At least two waypoints (up to a maximum of 125) are linked together to form a route. When you start your trip, you activate the route feature and the receiver points the way you should travel to get from the rst waypoint to the second. You can then use the pointer page to give you steering guidance.

Routes

Navigation Pages pointer becomes a bent pointer as you approach a waypoint within the route. Turn in the direction of the pointer arrow to continue the route.

190-00297-01_0C.indd 19

There are two ways to create a route: Use existing waypoints that reside in the Geko 201. Follow the instructions below to insert a waypoint into a route.
Plan a ROUTE in Garmin MapSource on your PC, and upload the ROUTE to the Geko 201. See your Garmin Dealer for more information about MapSource (MapSource is an optional accessory, and is not included with the Geko 201). In either case, you can navigate to a destination using ROUTE if a route has more than two waypoints. A single waypoint route is only a normal waypoint, not a route, so the on-screen FOLLOW Button cannot be selected if there is only one waypoint in the route. When you select the FOLLOW Button, a list with two items is displayed letting you choose where to go. The list alway shows the FIRST (BEGIN) and the LAST (END) waypoint in the route. The Geko 201 guides you following each waypoint in the route. There are two ways to insert a waypoint into a route. One way is to insert the waypoint before an existing waypoint in a route. The other way is to insert the waypoint at the end of the waypoint list in a route.
To insert a waypoint into a route:
1. From the MENU Page, press the UP or DOWN Button to highlight ROUTES and press the OK Button to display the ROUTES Page. 2. Press the OK Button to create a New Route. If there is no information in the route area, press the OK Button to display the ADD WAYPOINT TO ROUTE Page. 3. Press the UP or DOWN Button to highlight the waypoint of your choice and press the OK Button to place the waypoint in the rst eld on the ROUTES Page.

FOLLOW choice list

4. Repeat Step 3 until all of the waypoints you want are entered into the route list and then press the PAGE button to get back to the page of your choice.

North Reference

Reference refers to the orientation of a maps grid. Map makers try to align the vertical lines on a map with True North. True North is the direction from any location on the earths surface to the north pole. Maps are typically referenced to True North. Because a compass points to Magnetic North, not True North, maps indicate the difference between True and Magnetic North with a measurement called declination. The amount of declina-

190-00297-01_0C.indd 28

tion changes as you move around the earth. Magnetic North is the direction in which a compass needle points. The Geko 201 bearings will correspond to the compass if the Geko 201 is set to magnetic north. Due to errors introduced when map makers atten the earths sphere onto paper, not all of the grid lines drawn on the map point exactly to the north pole, so the north indicated by the grid lines is called Grid North. The difference, however, is usually small enough that Grid north can be considered the same as True North for traveling on land. If necessary, manually correct for the difference between Grid North and True North. If you select User for North Reference, the VARIATION eld is highlighted for you to edit the declination.
To change the North Reference:
1. From the MENU Page press the UP or DOWN Button to highlight UNITS and then press the OK Button to display the UNITS Page. 2. Press the UP or DOWN Button to highlight the NORTH REF eld and press the OK Button. 3. Press the UP or DOWN Button to highlight your selection and then press the OK Button. 4.

The Interface Page allows you to connect and use devices such as computers and differential GPS (DGPS) beacon receivers to the Geko 201.

Input/Output Settings

Interface
The Interface Settings Page allows you to use your Geko 201 with external NMEA devices, DGPS beacon receivers, a personal computer, etc. You can choose from seven different input/output serial data formats, or none at all. Below is a description of each format: GARMIN - default setting that allows you to update software and communicate with MapSource (transfer waypoints, routes, and tracks). GARMIN DGPS - allows DGPS input using a Garmin beacon receiver and a standard RTCM SC-104 format and DGPS tuning. NMEA - supports the output of standard NMEA 0183 version 3.0 data. TEXT OUT - supports the output of ASCII text location and velocity information. RTCM IN - allows DGPS input using a standard RTCM SC-104 format without any output capabilities. RTCM/TEXT- allows DGPS input using a standard RTCM SC-104 format and simple ASCII text output of location and velocity information. NONE - provides no interfacing capabilities. If GARMIN DGPS or RTCM In/NMEA Out format is selected, additional elds are provided to control a Garmin differential beacon receiver (e.g. GBR 21 & GBR 23) directly from your unit. Tuning is automatic with Scan or you can enter the beacon frequency and bit rate when you select User from the Beacon list to manually tune the receiver. Refer to the beacon receiver instructions.

Setup Page System

The System Page allows you to choose from four modes of operation (Normal, WAAS, Battery Save, Demo), change the language display, choose a battery type, include owner information, and view the software version on your unit.

GPS Mode

The GPS receiver is always ON when its in NORMAL mode. The normal mode is more responsive to sudden turns or change of speed/acceleration. When the Geko 201 is in BATTERY SAVE mode, the GPS receiver turns on and off alternatively to conserve power and the WAAS function is turned off. The battery type choice also can affect battery life; choose between ALKALINE and NIMH depending upon the type you are using.

The SYSTEM Page allows you to change the GPS Mode, the Language, battery type and owner information.
The DEMO mode is designed for dealers to show the features and functions of the Geko 201 to potential customers inside a closed building where satellite reception is not possible. There is no navigation possible in DEMO mode. If you select the DEMO mode, a window displays at the bottom of the screen asking you to verify that you want to turn the GPS off (the unit will stop tracking satellites, but not power off).

To change the GPS mode:

A BATTERY LOW message displays at the bottom of every page when there are approximately ten minutes of battery life left (when using alkaline batteries).
1. From the MENU Page press the UP or DOWN Button to highlight the SYSTEM eld. Press the OK Button to display the SYSTEM Page. 2. Press the UP or DOWN Button to highlight GPS MODE eld and press the OK Button. 3. Press the UP or DOWN Button to highlight your selection and press the OK Button. 4.

Using a hand-held GPS for Geography fieldwork

Key Words

GPS = Global Positioning System Waypoint = A GPS location Track = An electronic breadcrumb trail that records your movements
To record a new track, walk to the starting point and clear the
track log from the Menu page. Walk along the chosen route and at the end, save the track log by going to the Menu page and using the UP DOWN keys to select TRACKS. Press OK and then select SAVE. Use the UP DOWN keys to pick beginning and end points for the track and click OK each time. Make a note of the name of the saved track, or edit its name by using the UP DOWN and OK buttons. You can save up to 10 tracks in this way. A track contains information about your position, speed and elevation, as well as the time and date. You could use a track to record a gradient profile.
To record your position, press
and hold the OK button for a few seconds. A waypoint is saved. This might be a fieldwork site for example. The waypoint can be given a name by pressing the UP / DOWN arrow and clicking the OK button to edit the name (on the little flag)
. Communicating with a PC
Some digital map programs like Anquet or Memory Map can interact with your GPS. Otherwise, if you need to exchange information between the GPS and a PC you will need to use a third party application. My favourite is Easy GPS from www.easygps.com/

Using GPS data

Back in the classroom, you can export data from the GPS and plot your waypoints on maps and in Google Earth. You can also analyse your tracks and draw profiles and maps. Your teacher may save the GPS data for you on Shared Documents. You can use various websites to analyse and plot your GPS data. The most useful website is www.gpsvisualizer.com for plotting

your data.
