Space-Time Synchronization - Time Distribution

This project seeks to make accurate timing information available wherever it is needed. It provides businesses with accurate, traceable time-stamping. NICT's network time protocol server answers billions of requests every day.

For future applications, researchers work on miniaturized atomic clock chips. A novel cluster clock time infrastructure is being researched to dynamically connect many such small, mobile clocks, while also taking advantage of high performance stationary clocks when they are available. The newly-developed Wi-Wi technology provides low-cost tools for wireless time synchronization at the nanosecond level.

Business tasks of the Space-Time Synchronization and Time Distribution project

Time Business

---

NICT supplies business time information traceable to Japan Standard Time.

Network Time Protocol (NTP)

---

Public time synchronization for internet-connected systems.

Hikari Telephone JJY

---

Time synchronization by packets sent over the Hikari Telephone service.

Japan Standard Time is also made available by the broadcast of Standard Radio Time and Frequency signals as part of the project for Generation of Standard Time and Frequency.

Research tasks of the Space-Time Synchronization and Time Distribution project

Chip-Level Integrated Frequency Standard (CLIFS)

---

Also known as chip-scale atomic clock, it brings atomic clock performance to the end user.

Cluster Clock Infrastructure

---

When clocks are everywhere, how do we connect them efficiently?

Wireless two-Way interferometry (Wi-Wi)

---

provides affordable clock synchronization at the level of tens nanosecond.
