NTP stands for Network Time Protocol. It is a networking protocol used to synchronize the clocks of computers and devices over a network to a reference time source, usually an atomic clock or a GPS clock.
An NTP server is a network device that synchronizes the clocks on your devices with a highly accurate time source like atomic clocks.
✅GPS Time Server
A GPS Time Server is a device that keeps your network synchronized with atomic clock time using (GPS).
💠 Why GPS Time Server
Reliable and Independent Time Source:
The internet can be unreliable, experiencing outages or delays. A GPS time server provides an independent source of highly accurate time directly from atomic clocks via GPS satellites. This is crucial for projects requiring precise timing, even without internet connectivity.
Key Points:
- Purpose: Keeps system clocks accurate and consistent across devices.
- Functionality: NTP adjusts the local clock in small increments to match the correct time.
- Common Sources:
- Internet time servers (e.g.,
time.google.com,pool.ntp.org) - Internal servers (e.g., GPS-synced or master clocks like Mobatime)
- Internet time servers (e.g.,
- Port Used: UDP port 123
