Getting a Position Fix
Because the SporTrak attains information it needs from satellites
orbiting the earth, the antenna needs to have a relatively unob-
structed view of the sky. This allows the SporTrak to choose from
all satellites currently available.
If the view of the sky is poor due to large cliffs or buildings, heavy
foliage or other obstructions, the satellite signals can be blocked and the receiver
may take longer to compute a position fix.
You can observe the signal strength and the satellites being used on the Satellite
Status screen (described in the next section).
Holding the SporTrak — The receiver is designed to fit
comfortably in your hand. Hold the SporTrak in the palm of
your hand with the antenna pointing towards the sky.
