Troubleshoot frequent GPS signal loss and interference

To improve the satellite signal to your phone, go outdoors and start the GPS navigation software. Place your phone where there is a clear view of the sky or on the dashboard of a vehicle that does not have thermal glass windshields or windows. A direct line of sight is required between the iPAQ and the GPS satellites to access information from the satellites.

NOTE: Interference might take place close to tall buildings, large trees, and under very cloudy or overcast skies. Try to avoid these obstructions before using GPS.

Interference Type

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, or X-ray and MRI machines.

Tall buildings, large trees, and very cloudy or overcast skies.

How to Avoid

Place the iPAQ where there is a clear view of the sky or on the dashboard of a vehicle that does not have thermal glass windows.

Move away from interference source or switch off the interference source.
