Global positioning system antenna function - GF82.61-P-4106-04P

The satellite signals received by the GPS antenna (A2/23, A2/49a2)  are amplified by the integrated antenna amplifier and sent to the GPS receiver, where the signals are processed.

The feed to the GPS receiver is configuration-dependent.

In the configuration with radio, the output signal is forwarded to the GPS receiver via a coaxial antenna cable in the CTEL and TELE AID, D2B transmitter/receiver (A35/17)  .

In the configuration with COMAND, another GPS receiver is integrated in the operating, display and control module (A40/3)  .

The output signal is sent to the GPS receivers via a coaxial antenna cable. The antenna output signal is sent to the CTEL and TELE AID, D2B transmitter/receiver unit (A35/17) and  the operating, display and control module (A40/3)  via an antenna splitter.

IMPORTANT The GPS antenna (A2/23, A2/49a2)  is only used to receive  GPS signals; no signals are transmitted.
