gpsctl is a utility program written for Raspberry Pi computers using a U-Blox GPS board
gpsctl is a utility program written for Raspberry Pi computers using a U-Blox GPS board. The author's rig is a Raspberry Pi 3 Model B with a Uputronix GPS board, which uses a U-Blox MAX-M8Q GPS module. Some of gpsctl's functions are generic for any GPS that streams NMEA data to a Linux serial port, and these should work on any Linux system. Most of gpsctl's functions, however, are quite specific to the U-Blox products, and use their proprietary UBX protocol (again, on a serial port).Fri Feb 28 14:56:49 2020 - permalink -

Building Stratum 1 clocks with NetBSD
The entire desire to do this came about from reading about building a Stratum 1 clock using a Raspberry PI at http://www.satsignal.eu/ntp/Raspberry-Pi-NTP.html and from the use of a Sony radio clock to provide WWVB pulses from the WWVB receiver module that was used in the radio clock.Wed Sep 20 22:34:01 2017 - permalink -
However, all of the projects and examples I found used Linux which I did not really want to use. I much preferred to use NetBSD, but it lacked a number of critical features that would be required to make a properly working Stratum 1 clock. Interrupt support for the GPIO pins was needed and adding a PPSAPI driver that could be triggered by a GPIO interrupt would be necessary.- http://anduin.eldar.org/stratum-1/
