service provider’s name on it. Hold your phone
away from your body, giving the antenna clear
access to satellite signals. Do not cover the
antenna area with your fingers or anything else.
• Stand still. If possible, stand still until your phone is
finished determining your location. Moving your
phone at a walking pace while your phone is
calculating your approximate location may
substantially decrease GPS performance.
• 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a fix in strong satellite signal conditions with outdated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.
