Government establishes requirements of NavIC Receivers to empower indigenous navigation

• Date: October 2025
• Agency: Bureau of Indian Standards (BIS).
• System: NavIC -Navigation with Indian Constellation, an ISRO project.

Key Highlights:

• BIS presents standards of NavIC-compatible receiver, including signal acquisition, tracking, accuracy of positioning, time tolerance, resistance to interference, and environmental durability.
• The Standardisation guarantees credible performance in such sectors as transport, disaster management, agriculture, and location based services.
• NavIC provides the positional resolution of 1.5 metres and the time resolution of 50 nanoseconds on L1, L5 and S bands.

Strategic Significance:

• The demand of India to have its own navigation system is after they were denied access to high-precision GPS data in the Kargil conflict in 1999.
• NavIC raises the technological level of self-reliance, it becomes a part of the world navigation giants: GPS (USA), Galileo (EU), GLONASS (Russia), BeiDou (China).
• It is civilian-controlled, and is customized to regional and domestic needs, whereas GPS is controlled by the US military.

Operational Details:

• Since 2018 with seven satellites, IRNSS was approved in 2006.
• Covers 1,500 km beyond the borders and provides coverage throughout India correctly.
• BIS certification is now optional, and should gain more usage in smartphones, vehicles, and navigation systems.

Exam-Oriented Facts:

• NavIC = Navigation with Indian Constellation ISRO.
• Transmission of SPS in L1, L5 and S bands.
• Standards guarantee compatibility and consistency of performance.
• Critical measure towards technological sovereignty in space-based navigation in India.
