Key Highlights
- The 2,250-kg satellite is the second of five next-generation satellites in the Indian Regional Navigation Satellite System (IRNSS)
- Features indigenous atomic clocks with enhanced accuracy
- Extended operational lifespan of 12 years
- Compatible with L1 frequency, matching GPS standards
Technical Specifications: The mission will span approximately 19 minutes, placing the satellite in a Geostationary Transfer Orbit at coordinates 170 x 36,577 km. This launch marks the 17th GSLV mission and the 11th utilizing India’s indigenous cryogenic engine technology.
Strategic Importance: The IRNSS, also known as NavIC (Navigation with Indian Constellation), provides crucial positioning, navigation, and timing services across the Indian mainland and surrounding regions up to 1,500 km. The new satellite will enhance the existing seven-satellite constellation, addressing previous challenges with atomic clock malfunctions in earlier satellites.
Technological Advancement: The integration of L1 frequency capability significantly expands the system’s utility, particularly for consumer devices like fitness trackers and smartphones. This advancement aligns NavIC with global navigation standards, potentially increasing its adoption in commercial applications.
The navigation program began with IRNSS-1A’s launch in 2013, followed by subsequent launches establishing the complete constellation. Despite initial setbacks, including the IRNSS-1H launch failure and early atomic clock issues, the program has evolved significantly with improved technology and wider application scope.
With mobile phone chipsets now compatible with IRNSS signals, the system is positioned for broader civilian use. The successful integration of indigenous atomic clocks also marks India’s growing self-reliance in critical space technologies.
This milestone launch underscores ISRO’s commitment to advancing India’s space capabilities while promoting technological independence in satellite navigation systems.
