What does NavIC's operational shortfall tell us about the challenges of building indigenous critical technology?

NavIC was built to end India's reliance on GPS and GLONASS. Defence agencies of other countries run those systems, and they can degrade or deny the civilian service [1]. Yet only three of the 11 NavIC satellites launched now broadcast navigation signals [2]. Standalone positioning needs at least four. The shortfall shows that indigenous critical technology needs a lasting ecosystem, not just one-time launches.

What the shortfall reveals

• Hidden component dependence: A satellite can be healthy and still be useless for navigation. Five of the eight working satellites can now only broadcast one-way messages [2]. The government's own roadmap puts an indigenous space-grade atomic clock first [2]. This shows how one critical part can disable a whole system.
• No replacement buffer: NVS-02 (2025) could not reach its orbital slot because its oxidizer valves failed to open [3]. Replacements came more slowly than satellites were lost, so the fleet had no reserve.
• Device-level gaps: NavIC receivers relied on chipsets from Qualcomm (USA) and MediaTek (Taiwan). An Indian baseband chip, from a Hyderabad firm, arrived only in 2023 [4]. Owning the satellites does not give self-reliance if user devices still use foreign chips.
• Weak market pull: Handset makers enable NavIC only when it is reliable or required by law. A weakened constellation gives them less reason to do so, which slows the scale that domestic chipmakers need.
• Strategic cost: NavIC offers a Restricted Service for strategic users [5]. When it degrades, the armed forces fall back on GPS. That is the very dependence that the lessons of Kargil warned against.
• Institutional limits: One agency carried design, building, launch and operation, with a thin private supplier base. This made delays longer at every stage.

Way forward

Indigenous parts -> Spares in orbit -> Reliable service -> Device mandate -> Market scale
   (clocks)          (fast launches)     (>=4 satellites)     (phones)        (Indian chips)

Flow: each link depends on the one before it.

NavIC's troubles show that self-reliance means mastering the whole chain: parts, replacement satellites, devices and demand. India should build indigenous clocks into the NVS series [2] and keep spare satellites ready in orbit. It should also bring private industry in through IN-SPACe, and require NavIC in devices only once the constellation is restored. Done in this order, NavIC can serve both Atmanirbhar Bharat and India's strategic autonomy.
