GPS Enabled
• In a car. When using the GPS Enabled feature in
a car, position your phone so that the GPS
antenna has good access to GPS signals through
the car’s windows. Typically, the GPS antenna
has best access to GPS signals in a car when
placed near a window.
Note: Although moving your phone at a walking
pace decreases GPS performance, moving
it at the speed of a moving car does not.
• Stay in network coverage. Depending on who
your service provider is, the network will provide
your phone with information that helps determine
your location more quickly and accurately.
Updating Satellite Almanac
Data
Another way to keep the GPS feature of your phone
working well is to keep your satellite almanac data
up to date.
The United States government maintains an
almanac of data about where GPS satellites are as
they orbit the Earth. This information is available to
your phone. Keeping your satellite almanac up to
date helps your phone determine your location more
quickly.
The almanac contains information about the location
of satellites, their operational status, and other
satellite information. Keeping this information
updated enhances the performance of your GPS
feature. In most cases, your phone will be able to
get a fix in strong satellite signal conditions with
outdated almanac data, but it may take longer.
Note: When you make an emergency call, your
phone does not rely upon the almanac to
determine your location.
If your satellite almanac data is out of date, your
phone may prompt you to update it. Follow the
instructions that appear on the phone’s display. You
may be asked to go to a web site or call a customer
care number.
Setting Privacy Options
Your phone’s GPS privacy options control whether
Java applications on your phone or other software
applications may view the location of your
phone.You may set your phone to one of these GPS
privacy options.
Note: Privacy options do not apply to the
transmission of location information during
emergency 911 calls.
To set your GPS privacy options:
1 From the main menu, select GPS > Privacy.
