Chennai, Feb 19 (Agency) In a major milestone, the Indian Space Research Organisation (ISRO) has successfully completed the EMI/EMC tests for Lander for the 3rd Lunar/Moon Mission, Chandrayaan-3 for three days from January 31 to February 2. The tests were conducted at the U R Rao Satellite Centre, Bengaluru and Lander was one of the payloads to be carried by the Chandrayaan-3, which ISRO was planning later this year using its heaviest satellite launch vehicle GSLV-MKIII, which was used for the first two Lunar missions. ISRO said the EMI-EMC (Electro-Magnetic Interference/ Electro -Magnetic Compatibility) 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. This test is a major milestone in the realization of the satellites.
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. During the Chandrayaan-3 lander EMI/EC test, Launcher compatibility, Antenna Polarization of all RF systems, Standalone auto compatibility tests for orbital and powered descent mission phases and Lander and Rover compatibility tests for post landing mission phase were ensured. The performance of the systems was satisfactory, ISRO said. ISRO’s created history with its second Lunar Mission which was 99.99 per cent successful before the Lander Vikram crash landed on the Lunar’s South pole after it lost contact with the ISRO ground centres after travelling more 3.48 lakh kms in its maiden mission. The then ISRO Chief K.Sivan said the performance of the lander was in accordance with the plan till the altitude of 2.1 km, after which communication links got snapped.
