SSLV satellites no more functional after being put in incorrect orbit, ISRO claims
“SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit. Satellites are no longer usable. Issue is reasonably identified. Failure of a logic to identify a sensor failure and go for a salvage action caused the deviation. A committee would analyse and recommend. With the implementation of the recommendations, ISRO will come back soon with SSLV-D2. A detailed statement by Chairman, ISRO will be uploaded soon (sic),” ISRO claimed in an upgrade on its authorities Twitter deal with. (1/2) SSLV-D1/ EOS-02 Mission upgrade: SSLV-D1 put the satellites right into 356 kilometres x 76 kilometres elliptical exerciser orbit rather than 356 kilometres round orbit. Satellites are no more functional. Issue is fairly recognized. Failure of a reasoning to determine a sensing unit failing as well as choose a salvage activity– ISRO (@isro) August 7, 2022 In its initial SSLV objective, the launch lorry lugged The Earth Observation Satellite EOS-02 as well as the co-passenger pupil satellite AzaadiSAT. SSLV had actually endured ‘data loss’ in its incurable phase, after executing “as expected” in all phases. AzaadiSAT includes 75 hauls developed by women trainees from country areas throughout the country that were given advice. The hauls are incorporated by the pupil group of‘Space Kidz India’
Unlike the Polar Satellite Launch Vehicles (PSLV), the SSLV can bring hauls evaluating approximately 500 kg as well as release satellites right into a 500 kilometres reduced planet orbit. It makes use of strong gas– hydroxyl ended polybutadiene– to discharge the initial 3 phases, taking the hauls to the preferred elevation. The 4th phase consists of fluid propulsion-based Velocity Trimming Module (VTM) to put the satellites right into orbit.
