2020-06-15 A new home timeserver on order 3 weeks ago
After earlier tries to have a nice GPS-based timeserver for my home network I noticed a simple but very effective GPS 'hat' for the Raspberry Pi, the Raspberry Pi GPS Hat from Uputronix. While the Pi's are already taking over the home network just one more could be a nice addition. In the longer run this will probably replace the shed computer. So I ordered a Pi with an added dual-band WiFi adapter, a case, the GPS hat and a GPS antenna. The GPS hat has PPS support so I will get the time correct. With the instructions from 5 minute guide to making a GPS Locked Stratum 1 NTP Server with a Raspberry Pi it should be easy. If this all works I may even add the resulting Pi to the IPv6 NTP Pool. Update 2020-06-16: SOS Solutions came back with some bad news: the uputronix Pi GPS Hat isn't available anymore. I'm now looking at the comparable adafruit hardware which is somewhat more expensive, but offers the same options. Update 2020-06-18: And the adafruit hardware is also not available soon. I cancelled the GPS unit part of the order and I'm looking at sourcing a GPS module for the Pi from another source. The GPS hat which sossolutions no longer sells is originally from uputronics where a newer version of the Raspberry Pi GPS/RTC Expansion Board is listed as available on the site. Based on a ublox chipset which allows me access to a lot of the GPS data.
