constellation of 24 orbiting satellites located more than 20 000 km
(12 428 miles) above the earth. At any given time, several of the 24
satellites should be visible to the vehicle’s GPS receiver. Based on the
time for signals emitted by these satellites to reach the receiver, an
on-board computer will determine the vehicle’s location, typically within
30 meters (100 feet). In addition to latitude and longitude, the system
also determines heading and speed.
Vehicle positioning information is relayed to the Lincoln Security
Response Center only during roadside or emergency requests. The
response center will not be able to track your location while in an
inactive state.
Lincoln RESCU system limitations
•
Inoperative if cellular phone inactive or inoperative
Lincoln RESCU utilizes your vehicle’s cellular phone and will not operate
if cellular service has not been activated or if the phone is inoperative.
•
Inoperative if battery discharged or disconnected
Lincoln RESCU is powered by the vehicle’s battery and will not operate if
the battery is discharged or disconnected.
•
Inoperative if cellular phone is not installed in the vehicle
interface
Lincoln RESCU utilizes your vehicle’s cellular phone and will not operate
if cellular phone is not installed in the vehicle interface.
•
Potentially inoperative if vehicle involved in accident
If the vehicle is involved in an accident, some components can be
damaged, rendering your RESCU System inoperative.
•
Positioning capability degraded if satellite signals obstructed
Vehicle positioning is accomplished by receiving and interpreting signals
transmitted by satellites. If the signals are obstructed positioning
capability could be degraded or lost. This situation will be most prevalent
in urban areas populated with tall buildings. tunnels, underpasses,
parking garages, trees and similar structures could also adversely affect
positioning performance. Under these conditions, the system will operate
but the response center could have difficulty identifying your current
location. (The last valid position obtained before the obstruction is
retained, however, and will be sent.) The operator may depend on you to
provide verbal information regarding vehicle location.
