• ISRO has initiated 'Project NETRA' - an early warning system in space to detect debris and other hazards to Indian satellites.
  • Under the project, the ISRO plans to put up many observational facilities: connected radars, telescopes; data processing units and a control centre.
  • They can, among others, spot, track and catalogue objects as small as 10 cm, up to a range of 3,400 km and equal to a space orbit of around 2,000 km.
• GPS Aided GEO Augmented Navigation (GAGAN): Regional Satellite Based Augmentation System (SBAS).
  • It is a step by the Indian Government towards initial Satellite-based Navigation Services in India.
  • It is a system to improve the accuracy of a global navigation satellite system (GNSS) receiver by providing reference signals.
  • The Airports Authority of India (AAI) and Indian Space Research Organization (ISRO) have collaborated to develop the GPS Aided Geo Augmented Navigation (GAGAN) as a regional Satellite Based Augmentation System (SBAS).
  • The GAGAN's goal is to provide a navigation system to assist aircraft in accurate landing over the Indian airspace and in the adjoining area and applicable to safety-to-life civil operations.
  • GAGAN is inter-operable with other international SBAS systems
  • GAGAN is the first Satellite-Based Augmentation System in the world which has been certified for approach with vertical guidance operating in the equatorial ionospheric region.
  • GAGAN covers the area from Africa to Australia and has expansion capability for seamless navigation services across the region.
  • GAGAN provides accuracy, availability, and integrity essential for each phase of flight, en route the approach for airports within the GAGAN service volume. This makes airline operations more efficient and effective, increase air safety, and fuel efficiency.
  • Further, with vertical guidance at runways, a significant cost will be saved due to withdrawal of ground aids and reduced workload of airline crew and traffic controllers.
• Gagan Enabled Mariner's Instrument for Navigation and Information (GEMINI) device:
  • It is a device that used for seamless and effective dissemination of emergency information and communication on disaster warnings, Potential Fishing Zones (PFZ) and Ocean States Forecasts (OSF) to fishermen.
  • It has been developed by Indian National Centre for Ocean Information Services (INCOIS), and Airports Authority of India (AAI).
