Few months ago, I've made a similar work but I wanted something a little more easier to manage. Please have a look at here for my previous work.
This time, I'm gonna do pretty much the same thing but using Pi-hole as base then modify it to include unbound and stubby.
This way, I can use the power of Pi-hole with some additional security layers:

So, I want to have a GPS Receiver driving a PPS (pulse-per-second) signal to the NTP server for a highly accurate time reference service.
There are at least a couple of ways to propagate the PPS signal to the ntpd (NTP daemon) service, plus some variants in each case. However, the GPS device must be seen as a device that sources two different types of data:
The first one provides the complete information (incl. date and time) about when now is, but with poor accuracy because data is sent over the serial port and then encoded using a specific protocol such as NMEA (National Marine Electronics Association). PPS provides instead a very accurate clock but without any reference to absolute time.
