In a boost to India’s moon mission, Chandrayaan-3 successfully underwent EMI/EMC (Electro – Magnetic Interference/ Electro-Magnetic Compatibility) at U R Rao Satellite Centre, Bengaluru. The test was conducted between January 31 and February 2, the Indian Space Research Organisation (ISRO) announced on Sunday.
WHAT IS EMI-EMC TEST?
The EMI-EMC test is conducted for satellite missions to ensure the functionality of the satellite subsystems in the space environment and their compatibility with the expected electromagnetic levels. Chandrayaan-3 interplanetary mission has three major modules: the Propulsion module, Lander module, and Rover. “The mission’s complexity calls for establishing radio-frequency (RF) communication links between the modules,” Isro said.
During the EMI/EMC test, launcher compatibility, antenna polarization of all RF systems, standalone auto compatibility tests for orbital and powered descent mission phases, and Lander & Rover compatibility tests for the post-landing mission phase were ensured.
