Nokia N78 - Manual (Page 36)

When you activate A-GPS, your device receives useful
satellite information from an assistance data server
over the cellular network. With the help of assisted
data, your device can obtain the GPS position faster.
Your device is preconfigured to use the Nokia A-GPS
service, if no service provider-specific A-GPS settings
are available. The assistance data is retrieved from the
Nokia A-GPS service server only when needed.
You must have an internet access point defined in the
device to retrieve assistance data from the Nokia A-GPS
service over a packet data connection. To define an
access point for A-GPS, press , and select Tools >
Settings > General > Positioning > Positioning
server > Access point . A wireless LAN access point
cannot be used for this service. Only a packet data
internet access point can be used. Your device asks for
the internet access point when GPS is used for the first
time.
Hold your device correctly
The GPS receiver is located in the top of the device.
When using the receiver, from an upright position,
move the device to an angle of about 45 degrees, with
an unobstructed view of the sky.
Establishing a GPS
connection may take
from a couple of
seconds to several
minutes. Establishing
a GPS connection in a
vehicle may take
longer.
The GPS receiver
draws its power from
the device battery. Using the GPS receiver may drain
the battery faster.
Tips on creating a GPS
connection
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. See "Hold your device
correctly", p. 36.
● If the weather conditions are bad, the signal
strength may be affected.
