Intro:
• IRNSS (now called NavIC) – an independent regional navigation satellite system developed by ISRO.
• Provides accurate position info in India and surrounding region (up to ~1,500 km).
Need for IRNSS:
• Strategic Autonomy – Reduce dependence on foreign systems like GPS (USA), especially during conflicts.
• Civil & Military Use – Required for secure, reliable navigation services.
• Regional Accuracy – Designed to provide better accuracy (~<20 m civilian, ~<10 m encrypted) for Indian region.
• Disaster Management & Emergency Response – Independent system aids in faster response.
• Economic & Technological Development – Encourages indigenous tech growth.
Navigation Applications:
• Land Navigation – Real-time tracking of vehicles, transport logistics.
• Marine Navigation – Route guidance for ships in Indian Ocean.
• Aviation – Assists aircraft in en-route navigation.
• Disaster Alerts – Used for tsunami, cyclone warnings.
• Surveying & Mapping – High-precision data for infrastructure and planning.
Conclusion:
• IRNSS/NavIC enhances India’s self-reliance in navigation, bolsters security, and supports economic and technological advancement.
