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" and "DATA RECEIVED" will respectively be displayed on the Message Center. 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 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 thousand kilometers 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 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. 152
