Page 5: Introduction
GPS receiver at a price that was impossible just a few years ago. The ® Rockwell receiver built inside has 12 channels that will track all of the satellites that are in view of your location. It’s acquisition time and tracking ability are second to none in its class. -
Page 6: S/A - What Is It
GPS receiver less accurate. These er- rors are called selective availability, or SA. How bad is it? They guarantee that the position reported by a GPS receiver that meets their specifica- tions is within 100 meters horizontally and 150 meters vertically 95% of the time. -
Page 7: Getting Started
GPS receiver and charges the DR-121. You can even use the receiver while the battery is charging! To install the NiMH battery, remove the battery cover and place the bat- tery into the compartment as shown on the next page. -
Page 8: External Antenna
This unit does not supply power to the antenna. OPERATION Keyboard There are 12 keys on the keyboard. You navi- gate through the menus, adjust the chart’s cursor, and enter data using the arrow keys. PAGES The five major modes of operation are ac- cessed using the PAGES key. -
Page 9: Turning Power On
The GPS receiver is tracking satellites that are sur- rounded by a black box. If the satellite number is not surrounded by a box, then the receiver hasn’t locked onto that satellite and it isn’t being used to... -
Page 10: Finding Your Position
Finding Your Position Auto Search To lock onto the satellites, the GPS receiver needs to know it’s current position, local time, and date. (Elevation (altitude) is also used in the equa- tion, but it’s rarely required to determine a position.) It needs this data so that it can calculate which satellites should be in view. -
Page 11: Quick Initialization
The unit returns to the satellite status screen. Using the quick initialization method loads a position that’s close to yours into the GPS receiver. It should now have position, time, and date, thereby giving it the data it needs to determine which satellites are in view. Once the satellites are known, the receiver searches for only those satellites, making a lock much faster than an auto search method. -
Page 12: Position Acquisition
The unit returns to the full initialization screen. Repeat this for each of the other settings until they’re correct for your location and time. Note: The position doesn’t have to be very accurate. If you enter a posi- tion within one degree of your actual location, the unit will be able to acquire the proper satellites. -
Page 13: Navigation Screens
To change modes, simply press the PAGES key. A screen similar to the one at right appears. Use the up or down arrow keys to change modes. (The windows mode is shown as “GRP” (groups); group “A” is the first windows group.) Press the right arrow key while the above menu is show- ing to switch between different versions of each mode. -

in the center. If you drift off course to the left, the line moves to the right . This signifies that you need to steer to the right to get back on course. This is called “chasing the needle”. If you steer towards the line (needle), you’ll always be heading in the correct direction to get back on course. -
Page 16: Cursor
Plot-3 (see at the top of the next page) is similar to plot-2. The major difference is the steering arrow and waypoint information at the bottom of the screen. When you navigate to a waypoint, the waypoint’s name and number show at the bottom of this screen. The steer- ing arrow always points in the direction to the waypoint. -
Page 17: Plotter Orientation
From the Plotter Options menu, choose Update Options to change the update rate or type. Select the option that you wish to change, use the left or right arrow keys to adjust it, then press the EXIT key to erase the menu. -
Page 18: Plot Trails
The course-up mode locks the top of the screen into the original bearing to the waypoint when navigation was first started. (See the navigation section for more information on course, track, and waypoint navigation.) To select a plotter orientation, highlight the “ROTATE” label on the “Plotter Options”... -
Page 19: Icons
ICONS The plotter has 28 symbols or “icons” available that can be placed any- where on the screen. They can be used to mark fishing or hunting loca- tions, landmarks, boat ramps, and virtually any point of interest. An icon can be placed at your present position or at the cursor’s location. -
Page 20: Place Icon - Cursor Position
Place Icon - Cursor Position To place an icon at the cursor’s position, first use the arrow keys to move the cursor to the location that you wish to place the icon. Next, press the ENT key. Now select the icon using the arrow keys. When it’s highlighted, press the ENT key. -
Page 21: Windows
You can delete individual icons by selecting the DEL FROM PLOTTER menu from the Icon Options menu. Once this menu is selected, the unit returns to the plot- ter screen with the cursor activated as shown at right. Use the arrow keys to move the cursor to the icon that you want to erase. - Page 22 Group C This group consists of bearing, track, distance to go, and estimated time en route. Group D Bearing, distance to go, track, ground speed, estimated time of arrival, estimated time en route, velocity made good (VMG), estimated time of arrival, and CDI show on this screen.
- Page 23 Group G This screen shows the present position, bearing, dis- tance to go, track, and ground speed. Group H Present position, a large CDI, distance to go, and estimated time en route show on this screen. Group I - Set Local Time This screen includes a clock that shows your local time, estimated time of arrival, bearing, ground speed, dis- tance to go, and the small CDI.
- Page 24 Group J - Clock Alarm This group has both estimated time of arrival and en route, plus the clock and a clock alarm. To set the clock alarm, press the MENU key while this group is show- ing, then highlight the Clock Alm Set label and press the right arrow key.

Page 26: Reprogram Boxes
Reprogram Boxes The digital boxes on the PLOT-2 and both NAV screens can also be re- programmed, using a method similar to the one used to reprogram the window groups. To customize a screen, first switch to the screen that you want to custom- ize. -
Page 27: Waypoints
WAYPOINTS This GPS receiver gives you the ability to create your own database of locations, called “waypoints’. You can save your present position, cursor position, or enter a coordinate and save it as a waypoint. For example, you may wish to store the location of your parked car as a waypoint be- fore starting on a hike. -
Page 28: Saving Your Present Position As A Waypoint (Select Number Method)
Saving The Cursor Position as a Waypoint When the cursor is showing on the plotter and you press the WPT key twice, the cursor’s position is placed into the first available waypoint num- ber. In the example screen shown below, the cursor is placed at the desired location. -
Page 29: Selecting A Waypoint
SELECTING A WAYPOINT In order to edit or navigate to a waypoint, you must first select it. There are three ways to do this: by waypoint number, waypoint list, or nearest. All waypoint selection methods are on the main waypoint menu shown at the top of this page. -
Page 30: Edit Name
Edit Name You can assign a name to each waypoint. The name can have up to eight characters. To do this, first select Name Edit from the Options menu. A screen similar to the one at right appears. Press the up or down arrow keys to select the first let- ter in the name. -
Page 31: Waypoint Navigation
WAYPOINT NAVIGATION The GlobalNav 12 makes it easy to navigate to any waypoint. All you have to do is select the waypoint (see page 26), then highlight the “GO TO” label on the waypoint screen and press the right arrow key. The unit im- mediately shows navigation information to the waypoint on all navigation, plotter, and windows screens. -
Page 32: Navigating To A Waypoint Using The Plotter
Navigating to a Waypoint using the Plotter The unique “birds-eye” view used by the plotter gives you an easy way to navigate to a waypoint. On the plotter screen shown above, the diamond with a cross in it is your present position. The box with the “S” in it was your starting location when you recalled the waypoint. -

Page 34: Project A Waypoint
Project a Waypoint You can save a waypoint even if you don’t know it’s position or location on the plotter. This unit lets you project the location of a waypoint from a known way- point using only bearing and distance from the known waypoint. -
Page 35: Position Averaging
Position Averaging The effects of Selective Availability, described in the Introduction, can be minimized or virtually eliminated using position averaging. You can only save a waypoint using this method, however the location saved can be much more accurate than any other method without using DGPS. The downside to this method is twofold-It only works to save a waypoint and the unit must be in the location that you want to save, preferably for an hour. -
Page 36: Create A Route
Create a Route To create a route, first press the MENU key, highlight the “PLAN/EDIT ROUTES” label, and press the right arrow key. The screen shown at right appears. This unit can store up to 20 routes. Route number one shows on this page. -

unit returns to the waypoint list screen. The second waypoint shows be- neath the first one, with bearing and distance from the first waypoint in the route to the second showing under the second waypoint’s name. The total route distance shows at the bottom of the screen. Continue selecting way- points in this manner until all of the waypoints in the route are on the list. -
Page 38: Following A Route
Following a Route Before starting the route, you’ll need to decide if you want to start at the beginning and travel forward or start at the last waypoint in the route and travel backwards (reverse) to the first waypoint. The default is forward. To change it, press the MENU key, then select the “PLAN/EDIT ROUTES”... -
Page 39: Delete A Route
