I am having a slight problem with my uBlox EVK-7PAM GPS eval kit talking to GPSD. Basically, it seems to recognize the receiver okay, but then drops back to "Generic NEMA" mode. Maybe I am not understanding the debug messages correctly. I am trying to set up a Linux Fedora 20 system to act as a NTP server and use the GPS as a source clock. It seems to be working fine, and i have PPS / KPPS working okay. Can someone provide some insight into this issue? Below are a couple of excerpts from the log (-D 5):
