GPS EnabledYour phone’s GPS Enabled feature uses information 
from Global Positioning System (GPS) satellites 
orbiting the Earth to determine the approximate 
geographical location of your phone, expressed as 
latitude and longitude. The availability and accuracy 
of this location information (and the amount of time 
that it takes to calculate it) will vary depending on 
the environment in which you are using the GPS 
feature. For example, GPS location fixes are often 
difficult to obtain indoors,...

Walking or driving very slowly may also 
substantially reduce GPS performance.
Even where location information can be 
calculated in such situations, it may take much 
longer to do so, and your location estimate may 
not be as accurate. Therefore, in any 911 call, 
always report the location to the emergency 
response...

 Viewing Your Approximate Location
GPS satellite signals and network assist data, it may 
take 30 seconds or more to determine the 
approximate location. This time will increase where 
there is reduced access to satellite signals. When 
your approximate location is determined, it is made 
available to the appropriate emergency response 
center.
In some cases, your local 911 emergency 
response center may not be equipped to receive 
GPS location information. For this reason, and 
because the GPS...

 Updating Satellite Almanac Data
Stay in the open. The GPS feature works best 
where there is nothing between your phone and a 
large amount of open sky. If possible, go outside, 
away from tall buildings and foliage. While 
performance in a building is improved by moving 
closer to windows, glass with certain sun 
shielding films may block satellite signals.

Hold your phone to enhance reception. Signals 
from GPS satellites are transmitted to your GPS 
antenna, which is...

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...
