1.1.2 GPS Signal Reception
The TeleType Bluetooth GPS Receiver offers high position accuracy and fast Time-To-First-Fix
(TTFF). These rely on environmental factors, such as where the receiver is located and the initial state
of the receiver. While attempting a position fix, the receiver needs to be locked-on to at least four
satellites. The TeleType Bluetooth GPS Receiver then uses the signals received from the satellites,
along with data from the receiver's digital memory about the last position fix, in order to compute the
current location of the device.
Environmental factors that influence position accuracy and initial GPS position fix are:
· Tall buildings
· Narrow street and passageway
· Protection film on glass
· Heavy foliage
· Large cliffs
· Other obstructions where the satellite signals may blocked
· Poor satellite geometry situations
