Abstract : Fast radio bursts (FRBs) are brief radio pulses lasting only milliseconds and originating from distant galaxies. They present some of the most intriguing mysteries in astronomy due to the challenges involved in detecting and localizing their sources. To date, astronomers have only managed to localize a few dozen FRBs. The Bustling Universe Radio Survey Telescope in Taiwan (BURSTT) is an innovative radio array specifically designed to tackle this issue by both detecting and accurately localizing FRBs. BURSTT's unique capability for near-all-sky monitoring (covering 10,000 square degrees) combined with sub-arcsecond localization (less than 1 arcsecond) distinguishes it from existing FRB telescopes, allowing it to localize hundreds of FRBs each year. To enhance localization accuracy, BURSTT is expanding its network by establishing international outrigger stations. One crucial station is located at the Raman Research Institute in Gauribidanur, Bangalore, India. The distance between the main BURSTT station in Taiwan and Gauribidanur is approximately 5,000 kilometers, enabling us to achieve a high level of accuracy (around 0.1 sub-arcseconds) in localizing FRBs. This precision will not only help identify the host galaxies of FRBs but also pinpoint their exact locations within those galaxies, representing a significant advancement in understanding their origins and the environments surrounding them. In Phase I of the project, we plan to install 16 antennas along with one RFSoC in 2024, which will be expanded to 64 elements by 2025. Additionally, we are conducting very long baseline interferometry (VLBI) tests between BURSTT-RRI and BURSTT-Taiwan.
