Elproma NTS Pico3 NTP / PTP Time Server

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.
