NTP Time + GPS time

Technical Support
1

I have a GPS connected through the usb port, and also a NTP server is defined within my country (Chile)… the command:

myshake@raspberryshake:~ $ ntpq -p  

  remote          refid          st t when poll reach   delay   offset  jitter
SHM(0)           .GPS.            0 l    8   16  377    0.000  382.182   3.708
*SHM(1)          .PPS.            0 l    7   16  377    0.000    0.331   0.438

I must understand that the time is defined by the GPS, and if for some reason, I lost connection to the satellites, the time will be set by the ntp server of my country?

I added the line:

server ntp.shoa.cl

to the file: /etc/ntp.conf

thanks in advance …

Hello rodrigosan,

Yes, that is correct. If the GPS loses the connection with the satellites, then the Shake will revert to using the specified NTP servers in the /etc/ntp.conf file, as you have done.
