Position finding, general
For position finding, the emergency call system control unit requires the global positioning system (GPS), a satellite-supported positioning system.
It is available worldwide. The GPS satellites permanently transmit time and position data (longitude and latitude).
Relocation with GPS (after interruption of satellite reception) may require several minutes (up to t = 20 min when emergency call system control unit is operated for the first time).
Position finding function sequence
The GPS receiver that is integrated in the emergency call system control unit receives the GPS signals from the left front GPS antenna (A2/23) via a discrete line. These are transmitted by the antenna splitter (A2/5).
The GPS signals are used by the emergency call control unit to calculate the current vehicle position (receiver). In addition, the vehicle's direction of travel is determined with the aid of the sequence of the locations calculated with GPS and stored in a history.
