ISRO Report on SSLV Mission Failure

News: Indian Space Research Organization deployed the Small Satellite Launch Vehicle in August 2022. (SSLV). Both of the two satellites it was carrying were rendered useless. The mission was deemed unsuccessful. A study outlining the causes of the mission’s failure was just released by ISRO. According to ISRO’s investigation, vibration disturbances were the main cause of the mission’s failure.

 

  • It was planned for the SSLV-D1 to launch the satellite into a 356 kilometre orbit. The satellite was instead given a 76-km orbit. Sensor failure was the reason of this.
  • The lack of velocity resulted in the incorrect orbital placement.
  • Vibrational disruptions took place at the second stage of separation. As a result of these vibrations, the sensors in the inertial navigation system started to malfunction.
  • A three-stage launch vehicle is the SSLV. The PSLV, on the other hand, is a four-stage launcher. Additionally, ISRO was using SSLV’s brand-new inertia navigation system for the first time. It employed six gyros in total to keep an eye on the rotation rates. During the flight, measurement saturation occurred in all of the sic gyros.
  • Smaller satellites were the focus of SSLV’s design. These launch vehicles were made to accommodate a payload of 500 kg. The primary goal was to lessen PSLV’s burden.
  • The Next Step ISRO is now working on another SSLV rocket. It’s anticipated that the SSLV-D2 would launch in the first quarter of 2023.
