सारांश
The article explains ISRO's GSLV F12 mission, which successfully launched the NVS-01 navigation satellite, marking the heaviest payload ever carried by a GSLV rocket. This mission is a significant milestone for India's indigenous navigation capabilities, as NVS-01 is the first of the second-generation NavIC satellites.
These satellites are designed to enhance the accuracy and availability of navigation services for both civilian and strategic users, reducing India's reliance on foreign global positioning systems like GPS. The successful launch further solidifies ISRO's expertise in complex cryogenic technology and heavy-lift capabilities.
पृष्ठभूमि
India's journey in space technology began with the establishment of ISRO in 1969. Over decades, it has developed indigenous capabilities in satellite manufacturing, launch vehicle technology (PSLV, GSLV), and satellite applications.
The development of a regional navigation system, initially named IRNSS and later branded NavIC, was a strategic imperative to reduce reliance on foreign systems like GPS, especially after the Kargil War highlighted vulnerabilities. The GSLV series, particularly the GSLV MkII with its indigenous cryogenic upper stage, has been crucial for launching heavier communication and navigation satellites into Geosynchronous Transfer Orbit (GTO).
