NTP Server GPS Source
I haven't come across any recent posts discussing successfully adding GPS hardware for a NTP Server source, so I though I would ping the community.
I already have pfSense serving time to my sub-net. My hardware (Protectli.com) has a COM port, USB ports, and an internal full length Mini-PCIe interface with external antenna punch outs.
Cost effective (sub ~$100), reasonably accurate (sub ~100 msec) GPS time source. I am not serving time for financial transactions, just time for 30+ systems (clients, servers, security system, cameras, etc.) in my home in the event of WAN loss (~1 week) and to reduce external NTP queries. Perhaps learn something in the process.
OPTIONS (with or w/o PPS)
- External Serial GPS
- External USB
- Internal Mini-PCIe card with external antenna
- Is it even necessary to add GPS time source?
- What methods and devices have proven to work?
- Pros/cons of each?
- Has anyone got a VersaLogic Mini-PCIe card (u-blox) to work with pfSense?
- Or just buy something like a separate TimeMachine and be done with it?
Thanks in advance,

This blows your budget but has worked well for us for many years. It's a standalone device, but we set our pf box up to use it as it's primary time source. Have not tried connecting via serial, only using NTP over the network.
