GPS or other radio time sources are not an essential requirement
for pool membership. What is essential is a static ip address,
reliable 24/7 internet connection and good choice or internet
ntp servers. Local time sources and GPS just provide a holdover
period in event of internet outages so that your pool server is
ready to repond to requests as soon as internet connection is
