A new system tool is being developed - nts-sync - a Windows service that synchronizes your system clock using NTS (Network Time Security, RFC 8915).
It replaces the built-in Windows Time Service (W32Time) with cryptographically authenticated time synchronization. It is available in the Software section in early version 0.4.0, free for personal use.
Additional new tool is NTS-Tester - a reference implementation of RFC 8915, tool for fast testing and diagnostics of NTS (Network Time Security) servers for MS Windows platforms. It is available in CLI and GUI versions. Testing of plain NTP servers also is possible.
Time synchronization is a critical component of any IT infrastructure. The existing NTP protocol distributed time in plaintext, without authentication, exposing receiving systems to potential cyberattacks.
Starting from November 2024, support for Network Time Security (NTS) was added to the existing Internet time-distribution service NTP.HR. With the activation of NTS on our infrastructure, client systems can now cryptographically verify that the timing information received actually comes from our servers unaltered.
On 15.3.2026. there are 68 known public NTS servers/server-pools around the world. Of those 68, two are located at the University of Zagreb - FER.
The Stratum-1 NTP and NTS services remain publicly available.
Synchrophasors are currently being used by utilities around the world for system model validation, situational awareness, stability analysis, islanding detection, disturbance analysis, and wide-area measurement and control.
REMLab is equipped with Synchrophasor Measurement System, consisting of:
- Power Quality and Revenue Meter SEL-735 - high-accuracy metering combined with detailed power quality analysis
- SEL-2240, Axion - a rugged, modular platform combining the communications, built-in security, and IEC 61131 logic engine with a suite of I/O, monitoring, and control modules to provide high-speed, deterministic performance over an EtherCAT® backplane. The Axion supports multiple utility and industrial applications on a single device.
New course starting from 2021/2022 (winter semester): Development of software solutions for Industrial IoT systems
Course offers students the opportunity to learn about IIOT solutions, industrial communication protocols for the exchange of process data in real-time applications for visualization and industrial process control as well as the concept of a digital twin. Students will learn to apply next-generation development platforms used in industrial environments. Basic and advanced concepts of development and scripting of SCADA system functionality in Python, JavaScript and cloud/edge computing technologies will be covered.
In addition, the possibilities of integration of advanced technological concepts (augmented and mixed realities) and the application of machine learning and artificial intelligence in technological processes and industrial plants will be presented.
LDM/REM Lab provides new workplace for research of LoRaWAN and other IoT and IoMT (Internet of Measurement Things - IoMT) applications.
Using different funding sources a number of components and sensors were acquired, operational LoRaWAN network and standalone Wanesy LoRaWAN server were launched in May 2020.
We welcome students interested in research activities and industry partners for research cooperation.
An auxiliary remote teaching system that provides remote access to laboratory equipment and computers was developed in March 2020 at the LDM / REM Remote Metrology Research Laboratory.
RemoteLAB enables remote access to measuring devices and computers at the Department of Fundamentals of Electrical Engineering and Electrical Measurements and is used in the course Metrology Fundamentals and Measurements in Technology Systems.
The portal NTP.HR was launched in December 2019., which provides Stratum-1 Internet time-distribution service via the NTP protocol. This service will be provided and maintained by the LDM/REM Lab personnel with the support of the Faculty of Electrical Engineering and Computing.
Starting from March 2020, it became a part of the project NTPPOOL, virtual cluster of timeservers providing reliable easy to use NTP service for millions of clients worldwide.
Starting from November 2024, support for Network Time Security (NTS) has been added.
Company MEINBERG Funkuhren GmbH & Co. KG donated IMS - LANTIME M1000 Time and Frequency Synchronization Platform. Platform consists of several NTP/PTP (IEEE 1588-2008) modules, redundant power system and GNSS receiver option.
The donated equipment will be used for research work in the Laboratory, but also for the maintenance of the public NTP platform for time distribution, www.ntp.hr.
We thank the company MEINBERG, who recognized the potential of our Laboratory, for this kind of support.
