7.24 What are the GPS working principles?
The phone sends its location information (latitude and longitude coordinates) to the
positioning background through the self-attached GPS module. Then, the positioning
background calculates the coordinates in the electronic map and marks the positioned object
on the map, which visually shows the current geographical location of the phone.
7.25 What are the differences between the GPS and the
base station positioning?
For the GPS, the phone sends its location information to the positioning background through
the self-attached GPS module, and the positioning background performs positioning. For the
base station positioning, the base station of the telecommunications service provider
determines the phone's location by calculating the distance between the base station and the
phone.
The GPS uses the satellites for positioning, which consumes more power but is more accurate.
The GPS does not work when the phone is indoor. The accuracy of the base station
positioning is lower, but positioning is supported indoors.
