Building a Strata 1 NTP server

As a quick first test, I built a quick adapter board between the GPS engine’s 2×5 pin header to the standard FTDI serial cable, with a diode and 0.3F capacitor (Yes, not micro Farads, 0.3 actual Farads) to keep the SRAM from losing the current GPS almanac every time I power cycle it (which cuts the GPS lock time down from 12.5 minutes to 20-30 seconds). The 1pps output from the received is connected to the CTS line on the FTDI cable.
Configuring GPSd is ridiculously simple: Tell it which serial port you have your GPS receiver connected to, and it figures out baud rate, which pin you have 1pps connected to, etc. Then just point your NTP server at two special local host addresses where GPSd makes the time information available.
