Using non-PPS receiver for ntpd?

[Stein, Josh]

Hello everyone,

 

  I currently only have access to a USB GPS receiver connected to an rPi which does not supply PPS data. Despite the lack of PPS accuracy, I would like to use this receiver as a clock source to the ntp daemon running on that Pi. This Pi in turn will serve time to the other devices on my setup giving me a relative synchronization of their clocks. In this particular instance, I can tolerate some pretty egregious jitter – on the order of tens of seconds.

 

My first question is fundamental – given the discussion in the guide here (https://gpsd.gitlab.io/gpsd/gpsd-time-service-howto.html), is it even feasible to use a non PPS receiver in this role?

 

 

TIA,

--Josh
