Hi,
I made a seismic noise measurement yesterday: no problem, the recording and the dating of the data with the GPS antenna was correct.
At the same place, today, GPS time is not used, and the data are badly dated.
I tried with or without standalone mode activated.
I did the usual tests :
myshake@raspberryshake:/opt $ ls /dev/ttyUSB*
/dev/ttyUSB0
myshake@raspberryshake:/opt $ sudo cgps -s
cgps: caught signal 2
myshake@raspberryshake:/opt $ ntpq -p
remote refid st t when poll reach delay offset jitter

myshake@raspberryshake:/opt $
the GPS antenna is recognized.
I send the logs, ans some pictures
Hope this helps.
