Shortly, No. A-GPS (Which stands for Assisted Global Positioning System) is just an advanced GPS chip. It allows for the device to locate GPS satellites far faster because it locates the device's approximate position based on information received by cell phone towers first. Without the GPS part, the phone would only be able to get an approximate location fix of several dozen meters, whereas GPS accurately places the device within around 3 meters (10ft).
Gps provides best path compare to Agps.
No, GPS tracking phones dot not have the ability to trace a persons position if the phone is turned off or if there is no cell phone service in the area.
Strictly speaking, GPS devices are passive and don't transmit anything (correlating received signals from a constellation of satellites). Many cellphones use Assisted GPS, sending GPS information to servers to improve positional accuracy (sent through the encrypted data channel). Breaking this encryption is non-trivial (only GSM is known to have a vulnerability). Therefore, it is practically impossible to use a program to externally monitor GPS or AGPS signals. However, many phones offer programs to monitor position on the phone (for example, the iPhone'sMaps application).
phones do not have to be a smart phone to have gps. just ask the salesperson for phones that have gps and see which one you like. there are lots of gps mobile phones that aren't smart phones.
Not all phones have GPS. And not all phones that have GPS have activated GPS upon first use. For many, you would have to enable the GPS first.
Most phones have GPS device inside. You can't get true gps though without it.
No not all cell phones have gps installed in them. You would need to research specific phones for that feature.
every iphone has GPs and i think black berries have gps aswell
There are a number of popular phones that have GPS capabilities. The Samsung Galaxy, HTC Droid Incredible, and Nokia 580, for example, each have GPS capabilities.
GPS on phones are very accurate. They work just as good as a regular car GPS because they both work off of a satelite that feeds them information.
GPS Chips are put into Mobile Phones, PDA's, and SatNavs.
Not all cell phones have GPS tracking chips. The only ones that have tracking chips are the smart phones, such as an iphone.
