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.
