Indian Satellite Navigation Policy – 2021 (SATNAV Policy – 2021)

Recently, a comprehensive SATNAV Policy 2021 has been proposed by the Department of Space to achieve India’s goal of achieving self-reliance in the satellite-based navigation and magnification services sector.

Satellite based navigation is a group of navigation satellites with the capability of global or regional coverage. Additionally, its supporting infrastructure is designed to provide all-weather functional, non-resistant, three-dimensional location, velocity and temporal data.

Main objectives of the policy:

  • The main objective of the SATNAV Policy-2021 is to ensure continuous availability of free-to-air navigation signals for civilian uses and safe navigation signals for strategic uses.
  • Working towards compatibility and interoperability of Indian satellite navigation and magnification signals with other global navigation satellite systems and Satellite based Augmentation Systems: SBAS signals.
  • Providing Position Velocity and Time (PVT) based services.
  • To continue and update Space Based Navigation Services (SBNS), and SBAS as part of the Government’s Atmanirbhar Bharat Abhiyan.
  • A secure SBNS is provided to the Indian strategic community through the Indian Navigational System (Navigation with Indian Constellation: NAVIC).
  • NAVIC or Indian Regional Navigation Satellite System (IRNSS) is an independent regional navigation satellite system developed by ISRO.
  • To provide SBAS services through GPS Aided Geo Augmented Navigation (GAGAN) for Indian airspace.
  • Developed jointly by ISRO and Airports Authority of India (AAI) to provide navigational services and positioning accuracy
