Added a non CFAR PCPS acquisition algorithm based on the estimation of
...
the post correlation noise floor. If enabled
(.Acquisition_1C.use_CFAR_algorithm=true) as an option in the
acquisition configuration, it allows setting more stable thresholds in
the presence of non-gaussian front-end noise (which is the usual
behavior of front-ends....)

Now the Galileo E1 receiver generates RTCM messages 1045 (ephemeris) and
MSM7 / 1097 (observables). Parameters related to RTCM included in conf
files. The TCP/IP server can be activated by setting flag_rtcm_server to
true.
