GNSS
The BC50R is equipped with the Telit Jupiter SL869 GNSS receiver module with 32
channels. The module supports GPS, Glonass and Galileo.
The GNSS signals are received via a U.FL antenna connector which has to be
connected to an external antenna.
The BC50R itself has no antenna. You need to select and connect an antenna
suitable for your application. The accuracy is mainly dependent on antenna quality.
Please note that MEN does not supply antennas with the BC50R, since the choice of
a suitable antenna depends on your application. The BC50R supports active and
passive antennas. An antenna supply voltage of 5V is provided.
The GNSS receiver converts the data received from the antenna to data packets. The
time mark signal is readable by application software. The data transfer rate is
configurable.
The GNSS module is accessed via a FTDI2UART chip. Under Linux the device port
is probably ttyUSB0. The baudrate is 115200 8N1.
The GNSS's power supply can be reset via GPIO. See
Chapter 4.2 SMBus
