GPS receiver board for Syncserver WNRO and Unlocked status

webmaster — 2025-02-06T15:17:53Z

Hardware upgrade of GT-8031 on S200 S250 S300 S350 XLi

This high performance GPS board will replace the Furuno GT-8031 board inside the S200 S250 S300 S350 and XLi, from Symmetricom / Microsemi, with very fast Time To First Fix, and high accuracy.

It fixes the WNRO (Week Number Roll Over) issue, which cause GT-8031 GPS receivers to display wrong date and time, and bug displaying "Status: Unlocked".
Future WNRO are managued unitl year 2099.

This plug-and-play GPS board offers greater compatibility with a wider range of GNSS satellite constellations (Glonass, Galileo, Beidou, QZSS).

This board has also a USB connection for easy remote configuration.

T109 GPS / GALILEO Time server with OSNMA

webmaster — 2024-06-27T14:43:27Z

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.
OCXO or Rubidium oscillator option.

GPS/GLONASS/ BEIDOU/ GALILEO Time server in SATA format

webmaster — 2021-09-09T15:05:15Z

The T108 SATA Time server / Multi-GNSS Clock has been designed to provide very accurate timing information trough an Ethernet link (using NTP/SNTP protocol), for Network synchronization and measurement applications, without the need to be connected to external Network, hence preserving your Network insulation.
It is a 2.5'' SATA board, very easy to integrate inside an embeded PC.
Based on a high performance 32 channels GPS/GLONASS/GALILEO/BEIDOU chipset with -160dBm sensitivity and T-RAIM algorithm, it delivers extremely accurate timing information, even in poor signal level conditions (indoor, urban canyons and signal obscured environments).
The OCXO oscillator offers high accuracy even if GNSS satelites signals have been lost.

They can also be used as a replacement and upgrade for users of the Trimble
– Lassen iQ / SQ (PN 46240-00, 46240-05, 46240-10, 46240-20, 46240-25, 54854-00)
– Lassen LP (39263-10),
– Lassen SK2 (PN 37824-B, 38116-20, 38116-25) , and for Rapco / Spectracom 2804 NTP server
– ACE (ACE II, ACE III PN 39818-C , 41265-00, 36576-A)
– Condor C1919B (P/N 67650-00)
– Condor C2626 (P/N 70896-00), with optional embedded GPS antenna
they are now EOL (end of life), and suffer the rollover bug (WNRO), displaying a wrong date.
– Symmetricom MicroSemi S200 / S250 / S300 / S350 SyncServer (M12 core) , as well as the Symmetricom XLi receiver

All our clone boards have exactly the same procotol as the original Trimble boards (TSIP, NMEA, TAIP)

Also, the N024, N016 and N021 ( ACE, iQ and Lassen SKII clones) integrate a processor, for matching with parity ODD, and additional software features (including future Rollovers management).
You can buy these boards form our stock, directly by contacting us by E-mail or phone.

These boards are a fix plug-ang-play solutions for replacement of obsolete GPS boards displaying wrong date.

We can also provide Copernicus II chipset (63530-00), new & original from our Trimble stock : https://www.ebay.fr/itm/137248321259

Containers automatic level measurement and report

webmaster — 2018-02-15T11:43:17Z

Automatic level measurement for containers
The N112-US module, designed in 2016 by Heol Design, allows a daily report of the level of a container of waste, liquids, or used clothing.
Waste collection is then optimized.

The built-in ultrasonic sensor measures the filling level of the container accurately, and transmits this value via E-mail, SMS or on a data server (in UDP).
The measurement interval is programmable from 2 minutes to 24 hours.
A motion detection (moving the container) or a door opening also triggers the awakening of the module and the sending of an alarm.

The transmitted data are as follows:
– measurement of the filling level of the container from 0 to 100%
– accurate GPS position within 3 meters
– time and date
– ambient temperature
– container door opening alarm
– motion detection alarm
– battery level
The built-in Lithium battery allows a range of 6 months to 1 year (depending on the period of awakening and the ambient temperature). It is easily interchangeable, since it is fixed by a strong magnet on the container wall.
The module itself can be fixed by screws or a permanent magnet.

GPS 'Sea Tracker' for lobster traps, oyster farms, and outboard motors

webmaster — 2018-02-15T11:42:43Z

The 'Sea Tracker' (N105-IP68) is an anti-theft GPS beacon, IP68 waterproof and shock resistant (molded in anti-corrosive resin, no connector, no button, charge through induction).
A specific version, hidden in an oyster, is also available for oyster farms.

Since 2011, it is used in lobster traps, oyster bags, outboard motors, and other marine / sub-marine applications to prevent from thefts.
In case of a movement, the Sea Tracker sends its GPS position by SMS, E-mail or to a data server, and you can follow it using Google Earth or FTS software (developped by Heol Design).
It integrates an accelerometer and a real time clock (to wake up system periodically or in case of a theft).
Water/air temperature is also indicated to the user.
The Lithium battery (low self-discharge technology) allows several months or years of autonomy in standby mode.

It covers 2G GSM band, as well as 4G bands LTE-M and NB-IoT for the latest release, ensuring very low power consumption and very far covering range.

This tracker is under patent.

Oyster thieves arrested thanks to GPS antitheft tracker

webmaster — 2016-04-26T17:08:12Z

This past March, triggering a sealed IP68-N105 tracer on an oyster farm in Portugal led to the arrest of individuals by the Police.
At night, the GPS tracker hidden in a bag oyster (which was in standby mode for several months at the seabed) warned SMS park owner an unusual move, which immediately alerted the police, with GPS live tracking.
