Getting a Position Fix

The unit is designed to fit comfortably in your hand. Hold the
MobileMapper Pro in the palm of your hand with the top end
of the receiver pointing towards the sky.
MobileMapper Pro's internal antenna, located in the top end
of the receiver, needs to have a relatively unobstructed view of
the sky. This allows the unit to receive signals from all the sat-
ellites currently available.
If the view of the sky is poor due to buildings, heavy foliage or
other obstructions, the satellite signals can be blocked and
the receiver may take longer to compute a position fix.
Your receiver will have the best view of the sky when you hold
it at eye level. You should also hold your receiver vertically.
This allows the internal antenna to function optimally for the
best accuracy. This is especially important when collecting
data for post-processing (unless you use an externa antenna).
