Abstract: The successful commissioning of the proposed methodology to synchronize the NIC-NKN in Delhi and Hyderabad with Indian Standard Time (IST) maintained by NPLI over NTP protocol over IoT framework is a significant accomplishment in the field of time synchronization. The proposed methodology utilizes an IoT framework along with a unique Stratum 1 NTP architecture that is supported by a pre-calibrated Rubidium frequency source. This architecture enables the establishment of stratum 1 synchronization at the two locations, thereby ensuring that the time is accurately synchronized with the NPLI maintained Indian Standard Time (IST). The successful implementation of this methodology has several benefits. Firstly, it ensures that the time at the NIC-NKN in Delhi and Hyderabad is accurate and synchronized with the Indian Standard Time (IST) maintained by NPLI. This is crucial for various applications where precise timing is critical, such as in telecommunications, financial transactions, and scientific research. Secondly, this methodology can be extended to other locations and organizations that require accurate time synchronization. With the increasing use of IoT devices, the need for accurate time synchronization is only going to increase. This methodology provides a reliable and scalable solution that can be easily implemented in various organizations and locations. Thirdly, the use of pre-calibrated Rubidium frequency sources ensures that the time synchronization is accurate and stable over a long period. This is important as small inaccuracies in time synchronization can accumulate over time and result in significant errors. The use of pre-calibrated Rubidiumfrequency sources ensures that the time synchronization is accurate and stable over a long period, thereby avoiding such errors. In conclusion, the successful commissioning of the proposed methodology to synchronize the NIC-NKN in Delhi and Hyderabad with Indian Standard Time (IST) maintained by NPLI over NTP protocol over IoT framework is a significant accomplishment. Thismethodology provides a reliable and scalable solution that can be easily implemented in various organizations and locations to ensure accurate time synchronization.
