New Delhi: The Indian Space Research Organization (ISRO) achieved another milestone today with the successful launch of the NVS-01 navigation satellite aboard the GSLV-F12 expendable rocket from Sriharikota in Andhra Pradesh.
Approximately 20 minutes after liftoff, the rocket effectively deployed the satellite into a geosynchronous transfer orbit (GTO) at an altitude of approximately 251 km, according to ISRO. This launch marks a significant advancement for ISRO, as the GSLV-F12 rocket will facilitate future space missions and accommodate larger payloads.
The GSLV rocket, which had encountered a past failure, carried the NVS-01 satellite as part of a new generation of communication satellites. This satellite series aims to establish a constellation of Indian communication satellites, offering an indigenous alternative to Global Positioning Systems (GPS). The primary objective is to enable users to obtain precise location data critical for various applications such as map services, regional navigation, and missile positioning.
ISRO has an array of missions planned for this year, including preliminary tests leading up to the Gaganyaan human space mission and the launch of Chandrayaan 3, which aspires to land a spacecraft on the moon’s surface.
Today’s launch by ISRO, headquartered in Bengaluru, ensures the continuity of NavIC (Navigation with Indian Constellation) services. NavIC is an Indian regional satellite navigation system comparable to GPS, providing accurate and real-time navigation within India and an approximately 1,500 km radius around the mainland.
NavIC signals are designed to deliver user position accuracy of better than 20 meters and timing accuracy of better than 50 nanoseconds.
ISRO developed the Navigation with Indian Constellation (NavIC) system to fulfill the country’s positioning, navigation, and timing requirements, particularly in civil aviation and military sectors. Previously known as the Indian Regional Navigation Satellite System, NavIC offers numerous applications, including terrestrial, aerial, and maritime navigation, precision agriculture, location-based services on mobile devices, and marine fisheries, among others.
NavIC comprises a constellation of seven satellites and a network of 24×7 operational ground stations. It provides two services: Standard Position Service (SPS) for civilian users and Restricted Service for strategic users.
NavIC SPS signals are interoperable with signals from other global navigation satellite systems such as the US GPS, Russia’s Glonass, the European Union’s Galileo, and China’s BeiDou.
Today’s mission signifies the sixth operational flight of the GSLV with an indigenous cryogenic stage. ISRO anticipates a mission life of over 12 years for the NVS-01 satellite.
