ISRO Panel Identifies Faulty Electrical Connection as Cause for NVS-02 Satellite Failure
An apex committee investigating the failure of ISRO's NVS-02 satellite concluded that a loose electrical connection prevented it from reaching the intended orbit. The signal to activate a key valve in the engine's oxidiser line failed to reach its destination, preventing the necessary orbit-raising maneuvers. NVS-02 was part of the NavIC constellation, intended to enhance India's regional navigation capabilities. Despite this, ISRO successfully launched the CMS-03 (GSAT-7R) communication satellite, which is vital for the Indian Navy's maritime domain awareness and space-based communications. The committee recommended systemic improvements for future GSLV and PSLV missions.
Key Points
- The NVS-02 satellite failed to transition from an elliptical transfer orbit due to a faulty electrical connector.
- NavIC (Navigation with Indian Constellation) is India's indigenous regional satellite navigation system.
- The CMS-03 (GSAT-7R) is a heavy communication satellite weighing 4,400 kg designed for naval security.
- The failure occurred during the 100th launch from the Sriharikota launchpad.
Exam Facts
- NVS-02 was launched aboard a GSLV-F15 rocket.
- NavIC provides positioning, navigation, and timing services over India and the surrounding region.
- CMS-03 is also known as GSAT-7R and is critical for the Navy's space-based communications.
