Last date for submission of paper: 15-Dec-2019; Contact person: Event manager; URSI-RCRS is a biannual conference which was hosted by INC-URSI (Indian National Committee for URSI (International Radio Science Union)) under Indian National Science Academy till 2017. The URSI-RCRS conferences attracted a wide number of researchers across India in the area of radio science. The last three series under RCRS have been organized very successfully and generated huge interest among the radio science research community. Therefore, the Indian Radio Science Society (InRaSS) was created and registered to host all future RCRS conferences and for spreading Radio Science in India. In 2019, InRaSS hosted the highly successful URSI flagship event called the Asia Pacific Radio Science (AP-RASC 2019) conference in New Delhi during 9-15 March, 2019. The meeting was attended by more than 750 delegates from all across the world. The proposed URSI-RCRS 2020 will be hosted by the IIT-BHU, Varanasi under the auspices of InRaSS and show a path toward the URSI General Assembly to be held in Rome in August 2020.
