[FOSS-GPS] Ublox NEO-M8N no GLONASS in RTKRCV

Hello everyone

I am trying to get a Ublox NEO-M8N working with rtkrcv on linux.
Connected over USB, I like to get GPS and GLONASS working in Single mode 
and later in kinematic mode.

I set the "pos1-navsys  =5  # (1:gps+2:sbas+4:glo+8:gal+16:qzs+32:comp)" 
for GPS and GLONASS, but I only get GPS Satellites.

I used on the same time, with the same antenna, at the same place a 
second Ublox NEO-M8N also connected over USB on a
WIN7 PC with RTKNAVI, and there I got with similar settings GPS and 
GLONASS Satellites.

So if there is not a software bug in rtkrcv, in my opinion there should 
be GPS and GLONASS Satellites visible if I type
  "satellites 1". The numbers of satellites if I type "status 1" is 
equal to the numbers of GPS Satellites only in RTKNAVI at the same time.

Or is there something wrong in my settings?

As configuration file I am using the ubx_m8n_glo_raw_1hz.conf, and the 
rtk_kinematik.conf you find below. I used rtklib 2.4.1 
p11.<https://github.com/tomojitakasu/RTKLIB/commit/b3d1441f24dc73bb6b0cb6138233349053692c73>

It would be nice, if someone with a Ublox NEO-M8N could retest this.

Thanks
