An Indian Space Research Organisation (ISRO) GSLV Mk II rocket (GSLV 2 CUSP 4) was successfully launched from Satish Dhawan Space Centre, Sriharikota, India at 0512 GMT on 29 May 2023. It carried NVS-01, a replacement satellite for IRNSS-1G. The 2,232 kg NVS 01 is, in fact, the first in a second-generation series of satellites for India’s domestically-developed regional navigation system, called Navigation with Indian Constellation (NavIC) aka Indian Regional Navigation Satellite System (IRNSS). The satellite was placed into a geosynchronous transfer orbit (GTO) by the rocket’s cryogenic GS-3 (CUS-15) /CE7.5 (upr.) upper stage, and will raise itself to its final operational position in the geostationary arc.
