All of my NTP servers are finally up and running! (For real!)
I had been having issues with the Sparkfun Trimble GPS Module and I finally contacted Sparkfun. They responded quickly and knew exactly what the issue was.
Turns out, the width of the pulse on the Pulse-per-second output of the Trimble is too short for the Raspberry Pi 2 to detect.
Sparkfun provided step by step instructions on how to download Trimble’s GPS Configuration software, connect the module to my computer, and reprogram the pulse width. Thank you Sparkfun!
So now I can finally be collecting statistics on all five modules. I’d like to get a least a week of data before beginning comparisons.
Stay tuned for more!
