ISRO's NavIC Expansion: New Satellites Boost Indian GPS

Bengaluru, March 28, 2026 – The Indian Space Research Organisation (ISRO) successfully launched two new NavIC satellites this morning, significantly enhancing India's indigenous navigation system. The launch, which took place at 6:02 AM from the Satish Dhawan Space Centre in Sriharikota, marks a major milestone in India's quest for self-reliance in space technology. This expansion promises improved accuracy and coverage for NavIC, offering a robust alternative to GPS, Glonass, and other global navigation satellite systems.

The PSLV-C67 rocket carried the two NavIC satellites, NavIC-L14 and NavIC-L15, into a geosynchronous orbit. These satellites are equipped with advanced atomic clocks and navigation payloads, designed to provide real-time positioning, navigation, and timing services. ISRO chairman Dr. S. Somnath, addressing the scientists after the launch, said, “This mission reinforces India’s commitment to providing a reliable and accurate navigation system for both civilian and strategic applications. The enhanced NavIC system will be a game-changer for various sectors, including transportation, agriculture, and disaster management.”

NavIC vs. GPS: A Comparative Look

While GPS, developed by the United States, has a global reach, NavIC’s initial focus was on providing accurate positioning within India and a region extending 1,500 kilometers around it. The addition of NavIC-L14 and NavIC-L15 aims to expand the coverage further and improve signal accuracy, particularly in challenging terrains. Here’s a quick comparison:

• Coverage: GPS – Global; NavIC – Primarily India and surrounding region (expanding).
• Accuracy: Both offer comparable accuracy, with NavIC aiming for higher precision in the Indian subcontinent.
• Signals: NavIC transmits on L5 and S bands, making it less susceptible to interference than GPS, which primarily uses the L1 band.
• Satellites: GPS has a constellation of over 30 satellites, while NavIC currently has 9 operational satellites after today’s launch.

Expert Opinions on the NavIC Expansion

Speaking to News Reporter Live, Dr. Meena Sharma, a space technology expert at the Indian Institute of Space Science and Technology (IIST), highlighted the strategic importance of NavIC. “Having our own navigation system reduces our dependence on foreign systems, which is crucial for national security. Moreover, the unique signals used by NavIC offer better performance in dense urban environments and mountainous regions,” reportersays. The enhanced accuracy will also benefit emerging technologies like autonomous vehicles and precision agriculture.

India Availability and Pricing

The services provided by NavIC are free for civilian use within its coverage area. Smartphone manufacturers are increasingly incorporating NavIC-compatible chipsets in their devices. Major brands like Realme, Xiaomi, and Samsung already offer smartphones with NavIC support in India. The government is also promoting the use of NavIC in various sectors through policy initiatives and incentives. The cost of the entire NavIC program, including the satellites and ground infrastructure, is estimated to be around ₹18,000 crore.

The expansion of NavIC is not just a technological achievement but also a symbol of India's growing prowess in space technology. With improved accuracy, expanded coverage, and increasing adoption across various sectors, NavIC is poised to play a pivotal role in India's development. This week's successful launch has solidified India's position as a key player in the global navigation landscape.
