Why in News
- A Union Minister recently launched the Indian Standard Time (IST) distribution demonstration network at the Regional Reference Standards Laboratory (RRSL) in Jakkur, Bengaluru.
What It Is
- The Jakkur facility is India's first high-precision time distribution system that uses Ethernet cables and advanced protocols to share Indian Standard Time (IST) across digital networks.
Developed By
- The Legal Metrology Division under the Ministry of Consumer Affairs leads this project together with NPL, ISRO, BSNL, and SEBI.
How It Works
- NPL and ISRO create an independent Indian Standard Time (IST) reference, which reduces India's reliance on foreign GPS systems.
- The system sends time signals through fibre-optic networks using the IEEE 1588 precision time protocol standard for exact clock matching.
- Connected devices automatically fix small time slips through phase-locking, maintaining timing accuracy down to less than 1 nanosecond.
Key Features of White Rabbit Technology
- The technology offers extremely accurate timing synchronization of less than 1 nanosecond across all linked equipment.
- It guarantees that timing data arrives at devices with predictable and fixed delays for smooth network operations.
- The system can support thousands of devices across digital networks that stretch over 1,000 km.
- The network relies on open-source technology developed by CERN, allowing India to build its own customized solutions.
Strategic Applications
- It protects defense, power grids, and nuclear plants from GPS spoofing and cyber timing attacks by using a local timing network.
- Accurate time stamping helps stock markets and digital banking platforms prevent financial fraud and complete transactions safely.
- The network provides essential timing support for 5G, 6G, quantum communication, and space missions to ensure fast data connections.
