Re: [gpsd-users] More than two GPS device

[Sandor R. Repas]

Dear Charles,

I have just found the solution.
The gpsd handles the PPS as a different device. Actually, my 3 gps devices were 
6 devices in GPSD.
I have modified the #define NTPSHMSEGS line in the gpsd.h file, and it works 
now.
It could be a build option, but I was not able to find it.

Best regards,
Sandor

Sandor, please include the list in your replies so that everyone can see the 
conversation. Also, someone else might have an idea for you.

OK, each one is known to be good separately and in twos. I'm out of ideas. 
Anyone else?
