Stratum-1 NTP server, part 1

I’m following the instructions here and here to try and make a Stratum-1 NTP server using GPS and a Raspberry Pi 2. If this works, I should have a very accurate NTP server for a very reasonable amount of money.


I ordered the Raspberry Pi 2 from Amazon, and the other parts from HAB Supplies in the UK. The total cost (prices include tax) was:

Raspberry Pi 2 £29.99
GPS expansion board £35.99
Antenna and cable £41.99
Postage £5.52
Total £113.49

Edit: I already had a spare 32GB SD card and power supply. If you don’t have those already, you’d need to buy them too.
