Digital / Analog NTP wall clocks

webmaster — 2015-12-31T12:49:17Z

The 4 digits and 6 digits digital NTP clock WCK00x display hour/minute or hour/minute/second with high visibility (up to 50m), on both sides.
The WCK009 has dual side-to-side display, for both local and remote times.
The analog NTP WCK002 wall clock displays hour/minute/second with high visibility.
Both are automatically synchronized by NTP/SNTP, for example driven by T101 or T103 NTP servers, synchronized by GPS.
It connects automatically to the local network thanks to the DHCP protocol, and detects automatically NTP servers available on the network.
International time Zone and Daylight saving time are managed easily through the web interface of the GPS Time server.
The Broadcast setting function enables all NTP clocks to get the same setting at the same time (network management system).
Mounting kits are also available for easy integration, as well as PoE (Power over Ethernet).

GPS GNSS ATEX + IECEx active antennas, up to 50dB

webmaster — 2015-12-30T16:11:26Z

With your GPS based Time Servers, Heol Design can provide several kinds of GPS/GNSS antennas, low loss cables up to 400m, lightning arrestor and mounting accessories, as a complete solution, whatever your application.
Even in extreme environments, our GPS antennas will provide, year after year, a perfect solution for fixed-site, rooftop, or embedded GPS Navigation or Timing systems (NTP, PTP).

Also, Heol Design has designed a performing Ex-d GPS active antenna, for systems requiring high performance in EX zone 1/21 and 2/22 offshore environments.
Thess certified ATEX or IECEx antennas is housed in a flameproof box designed to withstand exposure to corrosion (use of stainless steel aluminium marine resistant and anti-corrosive paint), shock, excessive vibration, extreme temperatures, rain, snow and sunlight. The globe is highly resistant to impacts. Several constellations are covered, with accuracy reaching centimetre. Antenna gain goes up to 50dB, enabling cable length up to 200m, without additional amplifier.

Heol Design can provide IECEX antenna with GPS L1 / L2 / L5, GLONASS G1 / G2, GALILEO, BEIDOU satellites constellations frequency ranges, as well as L band correction services (Veripos for example), and MSK beacon support for marine applications (283.5 - 325.0 kHz).
We have also released an IECEX version of with Trimble Acutime 360 or Acutime 720 smart antenna, with direct NMEA and TSIP outputs in RS422.

Time Service Software

webmaster — 2015-12-30T14:48:20Z

HEOL Time Service is a NTP / SNTP client, developped by Heol Design, to synchronize a target computer, by connecting to a Time server / GPS Clock (T101 or any other Time server).

On Windows operating systems, accuracy is about 1 to 5 milliseconds.

Accuracy and specific alarms are displayed at every connection, and can be sent automatically by E-mail.
