Experience the Forefront of GNSS Time Synchronization! "GNSS TimeSync 2025" Announced

IIJ will host "GNSS TimeSync 2025," the first technical seminar in Japan specializing in time synchronization using GNSS (Global Navigation Satellite System).

This event is a valuable opportunity for engineers involved in time synchronization protocols such as NTP and PTP to get a comprehensive overview of the latest technology trends based on GNSS.

What is GNSS Time Synchronization?

GNSS is utilized in many fields, including broadcasting, telecommunications, and finance, as a technology that can acquire accurate time from anywhere on Earth.

In recent years, with the spread of NTP (Network Time Protocol) and PTP (Precision Time Protocol), GNSS has come to play an increasingly important role as a source signal for time synchronization.

To obtain stable time via GNSS, an understanding of high-frequency technology—including radio waves, antennas, coaxial cables, and noise countermeasures—is essential. In particular, there is a need for opportunities for IT engineers to learn this knowledge systematically.

Why IIJ is Hosting This Seminar

This seminar was planned after IIJ realized that the importance of GNSS time synchronization is increasing at the field level while proposing PTP (Precision Time Protocol) technology in the broadcasting and telecommunications sectors.

In the process, we felt that despite the fact that knowledge of high-frequency technology such as antenna installation, radio wave reception, and noise countermeasures is essential for the proper operation of GNSS, there is a current situation where such practical knowledge is not sufficiently shared among engineers is a challenge.
In addition, there are almost no technical seminars in Japan specializing in GNSS time synchronization, and we have received many requests for a place for cross-industry information exchange.

For these reasons, IIJ believes that sharing the expertise of companies and engineers who actually utilize GNSS technology and improving the understanding and application skills of time synchronization technology regardless of the field is what is needed right now, and we have decided to hold this seminar with the cooperation of those active on the front lines.

Seminar Highlights

Lectures by Industry Leaders
Engineers and researchers from manufacturers and research institutions active at the forefront of GNSS time synchronization will take the stage. They will discuss the present and future across various fields.
Correct Understanding of Jamming and Spoofing
We will provide accurate information to "fear correctly" regarding the much-discussed threats to GNSS.
Corporate PR in the Exhibition Corner
In parallel with the seminar, an exhibition corner will be set up where each company will introduce their latest technologies and products. It is also ideal as a place for technical exchange.
