11. One-day online workshop entitled ‘NavIC: Development, Scope, and Applications’, 25 January, 2024

Global Navigation Satellite System (GNSS) is now routinely used for myriads of applications with reliability, precision, global, all-weather availability, and cost-effectiveness. Using satellite signals, GNSS provides accurate position, timing, and velocity (PVT) information. The Indian Regional Navigational Satellite System (IRNSS), also called the Navigation with Indian constellation (NavIC) is the regional navigation system designed, developed, and maintained by the Indian Space Research organization (ISRO).

A one-day online Workshop entitled “NavIC: Development, Scopes, and Applications” was organized by Indian Radio Science Society (InRaSS) on 25th January, 2024. It was co-sponsored by Commission C of the International Union of Radio Science (URSI). The main purpose of the workshop was to expose the participants on the present status, potentials, challenges, future, and various applications of the NavIC system. The invitation to the workshop was well-circulated globally with active support from United Nations Office of the Outer Space Affairs (UNOOSA), Vienna, Austria. As many as 468 researchers and students, from 33 countries with varying levels of experience, expertise, age and professional background had filled up the registration form. Out of these more than 300 applicants actually participated in the online event. The workshop program included 6 talks of 45 min each, delivered by experts from ISRO as well as academic and research institutions in India. All the talks were received with great interest as evident from the feedback submitted by the participants as well as from the discussions and many Q&A during the tight time schedule. The participants were also exposed to the state-of-the-art of the related hardware through presentations from 5 manufacturers in a “manufacturers’ session”. Finally, in the “round-table” panel discussion at the end of the workshop, the challenges and prospects were presented by the experts from academia, research, and industry. The workshop generated ample interest among all the stakeholders. Request for similar workshops with more focused topics were received; the participants also expressed their interest for physical workshops on the topics. All the participants who attended most of the sessions and filled up the feedback form were provided digital participation certificates. In addition, 12 young participants, below the age of 35 years, who scored the highest in an online Quiz, given at the end of the event were selected for the prize consisting of a good book on GNSS. The prize was partially financed using support from Commission C, URSI.

8. Tatarskii Memorial Lecture, 23 December, 2022

Propagation and Scattering through Turbulent Media by Dr Saba Mudaliar

Abstract: The need for studying wave propagation and scattering through inhomogeneous media appears in numerous applications in several branches of science. Tatarskii was a pioneer who developed most of the theoretical framework for this topic. Ishimaru is another pioneer who developed statistical models for physical phenomena across such diverse disciplines as acoustics, optics, electromagnetics, seismology, plasma physics, medical imaging, wireless communication, etc. We will review the classical theoretical approaches to this problem and briefly describe recent developments and path ahead.

Brief Introduction of the Speaker: Saba Mudaliar is a senior researcher at the Sensors Directorate of Air Force Research Laboratory in Dayton, Ohio. He has extensive experience working on propagation and scattering in statistically modelled environments. For the last 15 years he has continuously organized special sessions on random and complex media in IEEE Antennas and Propagation symposia and URSI meetings. He is on the editorial board of the journal Waves in Random and Complex Media. He is a guest editor for the 2023 special issue in honour of V.I. Tatarskii.
