Building a GPS based Raspberry Pi NTP Server (NEO‑7M + PPS)
In this video I’m building a Stratum‑1 NTP server using a Raspberry Pi 1 Model B and a NEO‑7M GPS module with PPS support. This setup provides highly accurate time synchronization for your home network, using GPS as the reference clock.
The setup is designed for long‑term operation, providing a consistent Stratum‑1 time source with minimal maintenance.
All the commands, configuration files, and wiring details are available on my Romanian wiki:

Hardware used:
• Raspberry Pi 1 Model B
• NEO‑7M GPS module with PPS
• GPS active antenna (typical ~28 dB gain)
• SD card (for Raspberry Pi OS)
• 5V power supply
Software:
• Raspberry Pi OS (or compatible)
