ISRO Successfully Test-Fires Cryogenic Engine for NVS-04 Navigation Satellite Launch
The Indian Space Research Organisation (ISRO) has successfully conducted a flight acceptance test of a cryogenic rocket engine. This engine is designated for the upcoming Geosynchronous Satellite Launch Vehicle (GSLV) mission, GSLV-F19, which will carry the NVS-04 navigation satellite into orbit. The test, which lasted 200 seconds, took place on November 5, 2026, at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu. ISRO confirmed that the engine's performance, including the ignition of both the Main Engine (ME) and the Gas Generator (GG), was satisfactory and consistent with pre-test predictions. This successful test is a crucial step towards the launch of India's next-generation navigation satellite, NVS-04, which is part of the Navigation with Indian Constellation (NavIC) system. NavIC is India's independent regional satellite navigation system, designed to provide positioning, navigation, and timing services across India and an extended region of approximately 1,500 km beyond its borders. ...
