India’s lunar mission, Chandrayaan-3 has successfully undergone EMI-EMC (Electro-Magnetic Interference/ Electro-Magnetic Compatibility). 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. The test was conducted between January 31st and February 2nd at U R Rao Satellite Centre, Bengaluru.
Key points of the Chandrayaan-3
Chandrayaan-3 lander EMI/EC test, Launcher compatibility, Antenna Polarization of all Radio-Frequency (RF) systems, Standalone auto compatibility tests for orbital and powered descent mission phases, and Lander & Rover compatibility tests for post-landing mission phase were ensured. The performance of the systems was satisfactory.
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.
Why is this test important?
The EMI-EMC test is conducted prior to satellite missions which ensure the functionality of the satellite subsystems in space as well as their compatibility with the expected electromagnetic levels. “This test is a major milestone in the realization of the satellites,” according to ISRO.
Highlighting the importance of the test, ISRO explained that since Chandrayaan-3 is an interplanetary mission has three major modules, the Propulsion module, Lander module, and Rover. It added, the mission’s complexity calls for establishing radio-frequency (RF) communication links between the modules.
