T109 GNSS NTP/NTS Server — Security and Precision, with Optional OSNMA

The T109 provides high-precision, secure time distribution for critical networks using GNSS references. Optional OSNMA anti-spoofing ensures cryptographic validation of Galileo signals, while multi-constellation reception maintains availability.
The T109 thus provides a precise and ultra-secure time reference for industrial, defense, energy (power plants, oil & gas platforms, etc.), and data center applications.

OSNMA: Open Service Navigation Message Authentication from European Space Agency delivers cryptographic verification of navigation data to protect against spoofing and ensure integrity of received time signals, from Galileo constellation.

Why Choose the T109?

Anti-spoofing: cryptographic validation of Galileo signals (OSNMA).
Redundancy: multi-constellation reception (Galileo + GPS) to avoid reliance on a single system.
Precision: microsecond-level synchronization for time-sensitive applications.
Performance: up to 10,000 NTP/NTS requests per second.
Compliance: designed to meet security requirements for critical infrastructure.

Network Protocol Security

NTS (Network Time Security): encryption and authentication of NTP exchanges to protect against spoofing and interception.
HTTPS: secure access to the web administration interface.
SNMPv3: industrial-grade configuration and monitoring.

Network Connectivity

4 Ethernet LAN ports (Lan1 to Lan4) — 1 Gb each.
2 SFP ports (Sfp1, Sfp2) — 2.5 GbE.
1 Ethernet WAN port — 1 Gb.

Each port supports independent network configuration (subnet, enable/disable, dedicated MAC address).

Other Features

HTTP/HTTPS web interface available in English, French, and Spanish.
Simple integration with existing NTP infrastructures.
OLED graphic display for status and parameter monitoring.
SSH, syslog, SNMPv3, DHCP.

T102 NTP Time station, IRIG to NTP converter

webmaster — 2015-12-30T14:17:45Z

The T102 module is a SNTP/NTP client/server, able to synchronize automated systems and industrial networks.
It synchronizes its clients through Ethernet (IEC61850 compliant) or external GPS receiver (NMEA input).
It can also be synchronized through IRIG-B, acting as a IRIG to NTP converter.
The T102 can track external events with a very high accuracy - few µs (via specific input, isolated and protected).
The T102 can generate programmable precise TOP signals, isolated at 2500V.
As the T102 doesn't include GPS antenna, you can integrate it at anyplace in your factory (it only needs to be connected to its server through Ethernet - can be T101 for example).
Thanks to its Power on Ethernet feature, you can install it easily with only one cable for Data and Power.
It is available in Rack or DIN rail mount.

T200 PTP Grandmaster Clock

webmaster — 2015-12-30T14:15:12Z

The HEOL-T200 PTP IEEE-1588 Grandmaster Clock / NTP Time server with GPS Clock has been designed to provide accurate timing information trough an Ethernet link (using Precision Time Protocol), for Network synchronization and measurement applications, without the need to be connected to external Network, hence preserving your Network insulation.

Based on a high performance 14 channels GPS chipset with very high accuracy, and TRAIM algorithm, accuracy is guaranteed with only one GPS satellite tracked.
It enables also fast start-up times in very hard environmental conditions, as only one satellite is enough at power-up to generate a precise Time-stamp (static applications).
It can include a very high precision Rubidium oscillator, with a drift as low as 1µs/day when GPS signal is not available.

Precision Time Protocol (IEEE1588) has been implemented, for applications that need sub-microsecond synchronization (Grand Master Clock).
The PTP V2 implementation of the HEOL-T200 is fully compliant to the IEEE 1588-2008 standard (on step or two steps clock, in Unicast or Multicast mode) and provides PTP management messages for monitoring and configuration (also available on HTTP server).
With dedicated PTP switches and T202 PTP client stations, HEOL DESIGN offers a complete solution for accurate time measurements networks.

T202 PTP slave time station, with PoE

webmaster — 2015-12-30T14:05:56Z

The T202 module is a PTP slave station, able to synchronize automated systems and timestamp external events in an industrial environment.
As the T202 doesn't integrate GPS antenna, you can install it anywhere in your system (it is just necessary to connect it to your LAN, so it can synchronize to an external PTP server – T200 GPS PTP master clock for example).
Using the Precision Time Protocol (IEEE1588), the T102 can be synchronized with 1µs accuracy to PTP master clock.
An isolated event input allows you to time-stamp events from external systems, with very high accuracy (±100 nanoseconds from local clock).
A highly accurate pps (TOP) signal is available on SUB-D9 or I/O connector (polarity, period, length, and delay compensation are configurable by user). It is also available with optional 1500V isolated static relay.
IRIG-B003 and A003 output are available in option on the I/O connector.
A RS232 or RS422 serial port can be accessed for remote control and monitoring (with NMEA protocol output).
In option, a Lithium battery powered internal RTC can provide timing information if no PTP master clock is available at power-up.
The Power On Ethernet enables installation of the T202 without the need for additional cables to
provide power. It also offers redundancy of the DC input in case of failure of one of them.

T103 : Embedded Time server

webmaster — 2015-12-07T09:34:16Z

Heol Design has improved again performance of its NTP/SNTP Time Servers, achieving less than 1 minute from power-up to provide accurate timing information.
And at power-up, if the T103 Time Server has already GPS Almanac and Ephemeris loaded in memory, then it is fully operational in about 20 seconds.
Then it becomes possible to power-up the T103 server only a few minutes per day, to synchronize the different elements of your system.
Also, if no GPS satellites are available at power-up (antenna disconnected or hidden inside a building), the internal RTC can provide timing information.
These features allow integration in mobile or static applications, where performance, size and power consumption are critical.
