The GSLV-F15 follows the GSLV-F12 mission which successfully carried NVS-01, the first of the second generation navigation satellites on May 29, 2023.The key applications of the NVs-02 satellite are terrestrial, aerial and maritime navigation, precision agriculture, fleet management, location based services in mobile devices, orbit determination for satellites, Internet-of-Things (IoT) based applications and emergency and timing services, ISRO said.NavIC comprises five second generation satellites–NVS-01/02/03/04/05 envisaged to augment NavIC base layer constellation with enhanced features for ensuring continuity of services.The NVS-02 satellite designed and developed by Bengaluru-based U R Rao Satellite Centre weighs about 2,250 kg. It has navigation payload in L1, L5 and S bands and employs a Tri-band antenna.The heart of the navigation payload is the Rubidium Atomic Frequency Standard (RAFS), an atomic clock which acts as a stable frequency reference for the navigation payload.The ranging payload consists of a CxC transponder used for two-way CDMA ranging to facilitate precise orbit determination, ISRO said.Narayanan, detailing ISRO’s journey, recalled the space mission being nurtured under the leadership of the legendary Vikram Sarabhai.
