The GSG-L1 is a GPS signal generator that emulates a single
GPSL1 signal. The main application is a simple but very fast
manufacturing test, to assure that the assembly is correct, that
the antenna is properly connected, and that the receiver can
receive and identify a satellite signal.
GSG-L1 provides a fast and cost-effective solution for production
test of GPS-receivers in e.g. mobile phones with integrated
GPS-receivers. Thanks to the wide RF level range from 70 to 170 dBm (-70 to -150 dBm calibrated), the sensitivity
of all types of GPS receivers can be verified with a
minimum of delay.
The GSG-L1 GPS Signal Generator generates an RF-signal,
an L1 carrier that is BPSK modulated with the C/A code and
navigation signal. The navigation data is transferred to the
GSG-L1 via the RS232 interface port from a host computer
SW. A PC control program is supplied, with an utility able to
generate GPS subframes from existing RINEX files.
