Enhancing GPS Performance
Enhancing GPS Performance
Sometimes the GPS feature of your device may be unable to complete a
location calculation successfully. If this happens when you are trying to
view your location on the device's display, you will see a message
indicating that your device cannot access satellites.
To improve accuracy and increase your chances of a successful
calculation, do the following:
•
Stay in the open
• Extend your device antenna
• Hold your device to enhance reception
• Stand still
• If you are stopped in your car , position your device near a
window
• Stay in network coverage .
IMPORTANT: Things to Keep in Mind
The availability, accuracy, and the amount of time that it takes to
calculate your location 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, in covered locations, between high
buildings, or in other situations where you have not established a clear
broad view of the sky.
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 center if you can and if you cannot, remain on the
phone call for as long as the emergency response center instructs you.
Even where adequate signals from multiple satellites are available, your
GPS feature will only provide an approximate location, often within 150
feet (45 meters) but sometimes much further from your actual location.
Advice on how to improve GPS performance is provided in “Your GPS
Location When Dialing 911” on page 48.
