I use a Raspberry Pi with an Adafruit GPS
<https://www.adafruit.com/product/746> - I run dnsmasq, gpsd, and chrony
with PPS from the GPS.  This gives me accurate (sub-microsecond) time and
accurate-enough (WAAS, so sub-5M accuracy) position, as well as providing
DHCP.  I configure my laptop to get its time from the pi (I set windows to
sync its clock every hour), and Roverlog is smart enough to talk to gpsd
for the position data.  If I happen to want more than one laptop, all I
need is a small Ethernet switch and I'm good to go.
