Abstract: Time is the only physical parameter which tells us about the origin and existence of nature. We cannot measure the start and end points of time, but we can measure the time interval with greatest accuracy out of the seven fundamental physical quantities. Various real-life applications and strategic applications require accurate time synchronisation starting from milliseconds to nanoseconds. In the present digital world accurate time stamping of data traffic is very important from tracing a communication to reconstructing the crashed stock market. Bombay Stock Exchange (BSE) is the fastest stock exchange in the world with 6 µs latency. It means it can execute more than 1.5 Lakh orders in a second. Time stamping is the only parameter to decide the sequence of the events for fair and transparent trading. In telecommunication systems the complete network should not exceed a time error budget of 1.1 µs to establish a call between the two subscribers. If two networks use two different time sources as their references, there will be call drops which lead to penalties by TRAI. Similarly, there is a requirement of 1 µs accuracy in isolating the faulty power transmission lines and thus protecting the complete electric substations. The most critical application of time is in positioning and Navigation where 1 ms error in the time shows a wrong position of approximately 300 km. Systems operated based on such Navigation systems (GPS) like a missile carrying a payload or for a ship travelling in sea this is a huge loss. In the present talk “Indian Standard Time (IST) and its application for safe digital India” we discuss the timing requirements in various cyber physical systems like power grid, telecom networks, Cyber security & navigation. The effect of a non-synchronised nation on its economic growth & digital governance. GoI initiatives to synchronise the complete nation with one reference time i.e., IST.
About the Speaker: Dr. Vattikonda Bharath presently working as a scientist in Indian Standard Time Division of CSIR – National Physical Laboratory, New Delhi. He completed his Electrical & Electronics Engineering, from JNTU Anantapur, Andhra Pradesh. Master’s degree from CSIR-NPL in “Advanced Material Physics & Engineering” from AcSIR, New Delhi. He completed his PhD in Development of Cesium atomic fountain clock, which is the primary frequency standard of India Standard Time (IST) from AcSIR, New Delhi. His present area of work is “Time & Frequency transfer through satellites”. He is the nodal person for providing time traceability at ±1ns to ISRO for Indian Regional Navigation Satellite Systems (IRNSS) to two centres located at Bangalore and Lucknow 24X7. One of the five Nodal members of the National Mega Project “Setting up of secondary time scales across 5 cities in India '' for the Ministry of Consumer affairs and in charge of the time scale lab at Ahmedabad. Nodal person to synchronise IST with International Time Reference (i.e., UTC) and other countries via Geo-Satellites.
All are welcome to attend the Lecture.
