Self-reliance in satellite navigation is both a strategic and an economic imperative. Discuss with reference to NavIC.

NavIC is India's own regional navigation system. It covers India and about 1,500 km beyond its landmass [2]. In July 2026 the government told Parliament that only 3 satellites were providing positioning, short of the 4 needed for standalone service [3]. The October 2026 launch of GSLV-F18/NVS-03 was therefore presented as a step towards self-reliance in critical technology [1]. India needs NavIC for both strategic and economic reasons.

Strategic imperative

• Assured PNT in crises: in a conflict, foreign GNSS like GPS can be denied or degraded. A system under Indian control keeps positioning and timing available for the armed forces and critical infrastructure [1].
• Maritime reach: the 1,500 km footprint covers the Indian Ocean approaches and supports maritime domain awareness [2].
• Indigenous critical parts: IRNSS-1F's imported atomic clock stopped working in March 2026 [4]. NVS-01 flew India's first indigenous atomic clock [5]. NVS-03 carries indigenous and imported clocks together [2].

Economic imperative

• Consumer market: NVS-03 adds an L1 signal alongside L5 and S [2]. L1 is the band most phones use, so NavIC becomes easier to build into phones and wearables.
• Electronics manufacturing: Made-in-India NavIC chipsets support domestic electronics manufacturing [6].
• Mandated demand: MoRTH's AIS-140 standard made NavIC-based trackers compulsory in public and commercial vehicles. They are fitted in over 15 lakh vehicles under pilot projects [7].
• Timing services: power grids, telecom and banking depend on precise time, and NavIC still provides it with 3 satellites [3].

Gaps undermining self-reliance

• No spare in orbit: ISRO lists eight IRNSS satellites in orbit [10], but only three still provide navigation [3].
• Single-vendor buying: CAG Report No. 27 of 2014 found ₹1.47 crore spent on IRNSS switches that were never used. They were bought from one vendor without a tender [9].
• Uneven adoption: NavIC is not yet mandatory in smartphones [8]. The government says multi-GNSS use removes any vulnerability [3]. That holds in peacetime but not when foreign signals are denied.

NavIC combines strategic insurance with industrial opportunity, but it can deliver neither without enough working satellites. Next steps: launch NVS-04 and NVS-05, both already at an advanced stage, in quick succession [3], and keep a spare in orbit. India should also develop at least two Indian suppliers for clocks and valves under the Indian Space Policy 2023, and link any phone mandate to the constellation's health. These steps would make NavIC a real pillar of Atmanirbhar Bharat and strategic autonomy.
