- PRATUSH stands for Probing ReionizATion of the Universe using Signal from Hydrogen.
- It is a future space radiometer mission designed by the Raman Research Institute, funded by India’s Department of Science and Technology.
- The mission aims to study the Cosmic Dawn, the epoch when the first stars and galaxies formed.
- PRATUSH will operate in lunar orbit, specifically on the Moon’s far side, to avoid Earth’s radio noise and ionospheric interference.
- The system uses a compact single-board computer (SBC) to control the antenna and process data with an FPGA (Field Programmable Gate Array) chip.
- Tests show the radiometer can detect extremely low noise, proving its sensitivity.
- Using SBC technology reduces weight and power, making the mission viable for space deployment.
