The eXplorist 210 uses information from the GPS satellites orbiting the earth to provide you with detailed
information about your exact location. This is the foundation that your eXplorist will use to provide you with the
necessary information to arrive at your destination.
The most common use of your eXplorist will be to provide you with the navigation tools you’ll need to arrive at
your chosen destination. The simplest route, and the one used most, is a GOTO route. This is a route that is
computed as a straight line from where you are to where you want to go.
Step One: Compute Your Position
The basic operation of your eXplorist is to use the GPS satellites to compute your present position. This is
done internally in the software of your eXplorist. The only thing that you need to do is to give your eXplorist a
clear view of the sky so that it can receive the signals from the satellites.
Do:
• Point the antenna up towards the sky.
• Maintain a clear view of the sky.
Don’t:
• Cover the antenna with your hand or other objects.
• Point the antenna down.
• Stand under trees or other heavy foliage.
Stand where the satellite signals are being blocked by large obstructions (such as
buildings, in a narrow canyon, etc.)
If you find that the eXplorist is not computing a position, just move to a place that
has a better view of the sky.
Anytime you want to view the status of the satellites and their signal strength,
switch to the Satellite Status screen. Here you will graphically see the satel-
lites and their relative signal strength. You need at least three satellites with
good signal strength (indicated by green bars) to compute your position. A
computed position with only three satellites is termed a 2D position fix. When
you are getting a 2D position fix, your elevation is not being computed. To add
elevation to your position fix, you need at least four satellites with good signal
strength. Positions that use four or more satellites are called 3D position fixes.
