The Indian Space Research Organisation (ISRO) is poised to achieve a monumental milestone with the countdown for its 100th mission officially underway. Set to launch on January 29, this historic event will see ISRO’s Geosynchronous Satellite Launch Vehicle (GSLV-F15) carrying the NVS-02 satellite into orbit, marking a new chapter in India's growing space capabilities.
The countdown for this mission began early on Tuesday, with the 27.5-hour countdown initiating at 2:53 am. The launch will take place at 6:23 am on Wednesday from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. This mission will also be the first under the leadership of ISRO’s newly appointed Chairman, V. Narayanan, who took office on January 13, 2025. It is an exciting time for the agency as it reaches this historic milestone while under the guidance of its new head.
The NVS-02 Satellite: A Step Toward Global Navigation Excellence
The NVS-02 satellite, a vital component in ISRO’s ambitious Navigation with Indian Constellation (NavIC) project, is designed to provide highly accurate position, velocity, and timing data not only for India but also for areas extending 1,500 kilometers beyond the Indian subcontinent. This satellite marks the second in a series of second-generation satellites, following the successful launch of NVS-01 in May 2023.
NavIC is India’s regional satellite navigation system, similar to the U.S. Global Positioning System (GPS), but tailored to provide precise and reliable service in the Indian region. The NVS-02 satellite is equipped with advanced features, including navigation payloads in L1, L5, and S bands and a ranging payload in C-band. These features will enhance the accuracy and reliability of India’s space-based navigation services.
Weighing 2,250 kg, the NVS-02 will help augment the NavIC system, which includes a constellation of five second-generation satellites. This upgrade is crucial for ensuring the continuity of high-quality navigation services, vital for a wide range of sectors such as terrestrial, aerial, and maritime navigation, precision agriculture, fleet management, mobile-based location services, Internet of Things (IoT) applications, and emergency response services.
A Vision for the Future
ISRO’s 100th mission signifies more than just technical prowess—it showcases India’s growing stature as a space power and its dedication to advancing technology for public welfare. From launching satellites for communication and Earth observation to developing navigation systems and interplanetary missions, ISRO’s achievements continue to inspire millions globally.
As the NVS-02 satellite embarks on its journey into space, ISRO stands at the threshold of even greater accomplishments. With future missions planned for lunar exploration, interplanetary studies, and the continued expansion of the NavIC system, the Indian space agency is determined to leave a lasting mark on the global space arena.
With this historic mission, ISRO has reaffirmed its commitment to advancing India’s space ambitions, providing essential services to millions and contributing to the global effort of making space exploration more inclusive, accessible, and beneficial for all.
