Navigating with the GPS 100

Waypoint
Your GPS 100 receives signals from Global Positioning System satellites that
are in fixed orbits (stationary relative to the ground) around the earth. By
acquiring – or locking onto – the signals from at least three satellites, your
unit can use triangulation to precisely determine your current position, elevation
above sea level and bearing (the direction you are traveling). As you travel,
the unit automatically acquires the strongest satellite signals available at your
current location. By becoming familiar with the unit's basic operating features,
you will be able to use its powerful navigational capabilities.
Track
Waypoint
A waypoint is a specific location that you ask the unit to record. In this
manual, you will learn how to mark your current location as a waypoint, or
set the coordinates for a waypoint anywhere in the world. You can create
and store up to 500 waypoints. You can have
the unit show you the direction of travel to an individual waypoint, or
how to navigate along a series of waypoints.
Track
Your GPS 100 automatically keeps a record of your travel, called a track. The
Route
unit shows you a map-like picture of your track. You can create and store up
to 10 different tracks. Each track can be recalled and used for navigation as
the unit shows you how to retrace the track again, either forward or in the
reverse direction. When traveling in unfamiliar territory, this is a quick and easy
way to make sure you always know how to get back to your starting point.
Route
A route is a series of waypoints which you choose to navigate in a specific
sequence. Up to 50 waypoints may be stored in a route. Once you have created
a route, your GPS 100 will guide you from waypoint to waypoint. As you reach
Trip Meter
each waypoint, the unit automatically begins navigating to the next one.
Trip Meter
Along with the navigational features, the trip meter in your GPS 100 keeps
accurate time, allowing it to precisely calculate your speed of travel,
average speed throughout your trip and estimated time of arrival (ETA) if
you have chosen a destination.

The Five Main Pages

In the following sections of this manual, you will learn how to use five main
pages to access all the features of your GPS 100:
Map Page
The Map page displays a map of your current position in relation to any
waypoints that you have selected. It can show you the direction of travel to
a selected destination. The Map page also shows you the track that you
have traveled along. If you have created a route, the map can show you
that route and your current position on it. (See page 9)
Gauges Page
The Gauges page displays a compass that shows your current direction of
travel or the direction to your next waypoint. The data field currently showing
"speed" is user-selectable. (See page 11)
Trip Meter Page
The Trip Meter page displays a number of user-selectable fields with information
about your current location, the progress you have made, your direction of
travel, your speed of travel and the time of your trip. (See page 13)
Nav Data Page
The Nav Data page allows you to store and select waypoints for navigation,
use the unit's automatic tracking feature and program and recall a route to
selected destinations. (See page 15)
System Page
The System page allows you to choose the various settings and formats that
the unit uses to navigate and display information. (See page 31)
NOTE: Whenever satellite lock is lost or GPS is turned OFF, certain
animation icons (below) appear on screen and continue to loop until GPS is
ON and/or satellite lock is re-acquired. (See page 41)
