Description
Elproma NTS Pico3 NTP / PTP Time Server is an ultra-compact GNSS network time server built for small networks that need accurate, reliable, and continuous time synchronisation. Despite its miniature size, it delivers enterprise-grade timing performance using NTP, SNTP, PTP IEEE 1588-2008, and gPTP 802.1AS TSN.
Designed for 24/7 operation, the NTS-pico3 features a built-in GNSS antenna module and includes a 30 metre SMA-ended coax cable with a marine antenna. It supports GPS and GLONASS simultaneously, allowing the server to maintain precise UTC reference time directly from satellite sources.
With hardware timestamping, the NTS-pico3 can achieve accuracy of less than 200 ns, making it ideal for industrial automation, control systems, time-sensitive networks, and other applications where precise synchronisation matters.
Elproma NTS Pico3 NTP / PTP Time Server – Ultra-miniature industrial time server
Small form factor with natural air cooling, ideal for installations where space is limited.
GNSS synchronisation
Built-in multi-constellation receiver supports:
- GPS
- GLONASS
High-accuracy timing
- < 200 ns accuracy with hardware timestamping
- GNSS receiver accuracy better than 15 ns (2 sigma)
Fast startup synchronisation
Very fast Time To First Fix (TTFF) with synchronisation startup of less than 0.5 ms ± 1 ppm.
NTP, SNTP, and PTP support
Supports a wide range of network timing protocols including:
- NTP v2, v3, v4
- SNTP
- PTP v2 IEEE 1588-2008
- gPTP 802.1AS TSN
IPv4 and IPv6 networking
Single 10/100 Mbps Ethernet port supports modern IP networks.
Holdover stability
The built-in TCXO holdover oscillator helps maintain time during temporary GNSS loss:
- Better than 4 ms error in the first hour
- Maximum 100 ms error after 24 hours
1PPS output
Can operate as a 1PPS frequency reference clock and includes 1 SMA 1PPS output.
Secure time delivery
Supports cryptographic authentication for NTP to improve timing security.
Flexible power input
Powered by 9–30 VDC, making it suitable for a wide range of industrial environments.
Elproma NTS Pico3 NTP / PTP Time Server Typical Applications
- Industrial automation systems
- Small & medium networks
- SCADA and PLC environments
- Marine and transport systems
- Time-sensitive networking (TSN) applications
- Security and surveillance systems
- Broadcast and telecom timing
- Test and measurement systems
If you need a small GNSS time server with NTP and PTP support, the Elproma NTS-pico3 offers an excellent balance of size, accuracy, and capability. It is particularly well suited to projects where space is tight but reliable and precise synchronisation is still essential.
