Common Reasons For Interference When Using GPS
Software
Interference Type
How to Avoid
Vehicles with thermal glass windows and windshields
Place the HP iPAQ where there is a clear view of the sky or on
the dashboard of a vehicle that does not have thermal glass
windows. If your vehicle has thermal glass, consider using the
optional external GPS antenna placed on top of the vehicle to
receive the GPS signal.
Cell Phones or other equipment radiating Radio Frequency
(RF) energy or emitting strong electromagnetic radiation. For
example, microwave ovens, high-power cordless phones, CB
radios, Walkie-talkies, HAM equipment, X-ray and MRI
machines, etc.
Move away from interference source or switch off the
interference source.
Tall buildings, large trees, and very cloudy or overcast skies.
Move away from interference source so there is a clear view
of the sky.
