7.6 GPS Receiver card
The GPS receiver card is a 3HE-slot card which is connected to the controller card via the
AT96 bus. It is equipped with a µBlox LEA-5H GPS chipset. All passive or active GPS an-
tennas operating on +5V DC (max.100mA) can be connected using the SMA plug on the
front plate. Together with the syncho-card, it is responsible for the synchronous (with neigh-
bouring radio base stations) sending of the data to the radio emitter. The yellow Sync-LED
blinks when the GPS chip generates a time impulse. The cable runtime compensation is
configurable up to the nanosecond domain.
