Date/Time: Saturday, April 9, 2022, 5:00pm Indian Standard Time

Speaker: Priyanka Das Rajkakati, Art and Business Development Advisor, The Exploration Company, France

Abstract: The first objective of this talk is to give a general introduction to the principles of Global Navigation Satellite Systems (GNSS) positioning ( GPS being an example)- how does your phone or receiver detect the signals from GNSS satellites and determine your position? Moving on, we delve into what is time-delay-Doppler-phase estimation in the context of GNSS, and how to characterize the performance of this estimation problem using Cramér-Rao bounds.

The second objective is to take a step away from technical science, and dive into the importance of art, culture and diversity towards sustainable and responsible space exploration.

Bio: Priyanka Das Rajkakati is Aerospace engineer and artist, with a particular fascination for lunar exploration. She obtained B.Sc. in Physics from St. Stephen's College, Delhi, India. Then she moved to France to pursue Engineering from Ecole-Polytechnique, followed by an industrial Ph.D. in Aerospace Engineering from Safran and ISAE-Supaéro. With Assamese roots, growing up in Delhi and later travelling the world looking for inspiration, she is also an accomplished artist, with an artwork currently in space on board the International Space Station. Actively involved in S.T.E.A.M. outreach and in promoting science among the youth, especially young girls, she has won numerous awards, including a feature in the Forbes India 30 under 30 list.

Target Audience: This is for a wider audience. In particular, higher secondary and college students and teachers are welcome.
