About GPS and satellite
signals
The Global Positioning System (GPS) is a worldwide radio
navigation system that includes 24 satellites and their
ground stations that monitor the operation of the satellites.
Your device has an internal GPS receiver.
A GPS terminal receives low-power radio signals from the
satellites and measures the travel time of the signals. From
the travel time, the GPS receiver can calculate its location to
the accuracy of meters.
The Global Positioning System (GPS) is operated by the
government of the United States, which is solely responsible
for its accuracy and maintenance. The accuracy of location
data can be affected by adjustments to GPS satellites made
by the United States government and is subject to change
with the United States Department of Defense civil GPS policy
and the Federal Radionavigation Plan. Accuracy can also be
affected by poor satellite geometry. Availability and quality
of GPS signals may be affected by your location, buildings,
natural obstacles and weather conditions. GPS signals may
not be available inside buildings or underground and may be
impaired by materials such as concrete and metal.
GPS should not be used for precise location measurement,
and you should never rely solely on location data from the
GPS receiver and cellular radio networks for positioning or
navigation.
The trip meter has limited accuracy, and rounding errors may
occur. Accuracy can also be affected by availability and quality
of GPS signals.
To enable or disable different positioning methods, such as
Bluetooth GPS, select Menu > Tools > Settings >
General > Positioning > Positioning methods .
About satellite signals
If your device cannot find the satellite signal, consider the
following:
• If you are indoors, go outdoors to receive a better signal.
• If you are outdoors, move to a more open space.
• Ensure that your hand does not cover the GPS antenna of
your device.
• If the weather conditions are bad, the signal strength may
be affected.
• Establishing a GPS connection may take from a couple of
seconds to several minutes.
