Building a Raspberry-Pi Stratum-1 NTP Server The Raspberry Pi as a Stratum-1 NTP Server As an experiment, I purchased one of the low-cost credit-card-size computers, and have configured it to run NTP (Network Time Protocol). I have also used this board with a GPS receiver with pulse per second (PPS) output to make a stratum-1 NTP server, but as I know little of Linux, it has taken some time to achieve this aim! There are some helpful Linux commands scattered throughout this page.

Universal Keygen Generator 2015 software key generator is an amazing tool to generate any software serial key to make it register its Keygen generator for any software.. Keygen generator for any software. Both the PT5300 Master clock reference and the LTC timecode for common video formats are kept stable and up to date by the GPS information. Once set up, the PT5300 simply locks to the GPS and runs hassle free from there. Should weather parameters, vegetation or tall buildings cause a lack of GPS coverage, the.

These notes are almost as much for my own records for the next time I need to visit this project, but I hope they may be helpful to others. Supersystem Always Never Again Zip here. If you want to get started quickly, with the best results for minimum fuss, please see my page. Please also see for issues with the Jessie release of Linux, and with the newer Raspberry Pi model 3.

I start by describing how to get the Raspberry Pi running with just a LAN connection - no display, keyboard or mouse - a so-called headless operation. I then describe how to configure NTP for your environment, and adding a GPS/PPS receiver to convert your box into a stratum-1 NTP server including the operating system updates needed. Next, I note a couple of problems I had with the first GPS receiver I tried, and how I cured those with a different GPS receiver to produce a stratum-1 NTP server consuming about 4 watts. The easiest approach with good performance is described. Since starting this page there have been two developments which make the process somewhat easier - a program has been developed which allows the use of an unmodified operating system by working in rather than kernel-mode PPS, and a module is now available which plugs directly onto the 26-pin GPIO header of the Raspberry Pi, so. My thanks to Folkert van Heusden and Anthony Stirk for these developments. • No soldering required - - uses GPIO 18 • - user-mode PPS support no kernel modifications required Note that the Adafruit GPS Hat uses GPIO 4, physical pin 7, so you would need to change the commands given in this document.
