In a recent breakthrough, the scientists at Raman Research Institute (RRI), an autonomous institute under the Department of Science and Technology, have unveiled STARFIRE. This algorithm is set to tackle the persistent issue of unwanted Radio Frequency Interference (RFI) in space, thereby elevating the data obtained from space-based astronomy missions to new heights.

Main Highlights:

  • STARFIRE, which stands for Simulation of Terrestrial Radio Frequency Interference in orbits around Earth, is a pioneering algorithm that takes the art of RFI estimation and mapping to a whole new level.
  • The brilliance behind its conception lies in the data harnessed from FM transmitter stations across six countries, including Canada, the USA, Japan, Australia, Germany, and South Africa.
  • It can estimate and identify RFI signals emitted by a myriad of sources such as FM radio stations, Wi-Fi networks, mobile towers, radar systems, satellites, and various communication devices.
  • Armed with its estimation and mapping prowess, astronomers are now better equipped to decipher the faint whispers of cosmic events that transpired eons ago.
  • One outstanding feature of “STARFIRE” is its ability to fine-tune radio antennas within the 40 to 200 MHz range. This delicate calibration unveils the  21-cm hydrogen line, holding the key to unraveling cosmic secrets that have eluded us for centuries.


With its revolutionary approach to combating RFI, it paves the way for a future where space-based astronomy reaches new heights. STARFIRE stands as a testament to human brilliance and perseverance in the face of cosmic challenges. The journey into the unknown has just begun, and STARFIRE leads the way.
