Location data retransmit capability
During an activation, the Lincoln Security Response Center operator has
the capability to initiate a retransmission of the electronic data message.
This may be necessary to ensure a more precise determination of vehicle
location or to track a vehicle that is moving. To accomplish the
retransmit, a special tone is sent to the vehicle by the response center.
In this situation you will temporarily lose voice contact with the operator
and the messages “SENDING LOCATION DATA/SENDING DATA” and
“DATA RECEIVED/DATA RECEIVD” will be respectively displayed on the
message center/audio display. After the data retransmission is complete,
voice communication will be restored and the CID, LAT, LON and HDG
message will again alternately toggle on the message center/audio
display.
Global positioning system
Vehicle location is continuously updated via Global Positioning System
(GPS) technology. GPS was developed by the U.S. Department of
Defense for worldwide navigational and positioning purposes. It utilizes a
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.
