‘India conducts Asia’s first demo of performance-based navigation for copters’

In News
  • India conducted Asia’s first demonstration of performance-based navigation for helicopters for a flight from Juhu in Mumbai to Pune using GAGAN satellite technology.
About GAGAN
  • GAGAN, an acronym for GPS Aided GEO Augmented Navigation, is an Indian Satellite-Based Augmentation System (SBAS).
  • It was certified by the Directorate General of Civil Aviation (DGCA) in 2015, marking a significant milestone for the Indian aviation sector.
  • Notably, only four space-based augmentation systems exist worldwide, with GAGAN being the first developed for India and neighboring countries in the equatorial region.
Benefits
  • GAGAN extends its benefits beyond aviation, offering advantages to various transportation modes and public services.
  • It enhances the accuracy, availability, and integrity of the GPS system, enabling users to rely on GPS for all phases of flight, from en route to approach, within the GAGAN service volume.
  • Moreover, GAGAN enhances precision in reporting the aircraft’s position, thereby making a valuable contribution to maintaining superior Air Traffic Management (ATM).
  • This technology also has applications in maritime, railroads, highways, defense services, the telecom industry, security agencies, and personal position location applications.
Applications
  • The GAGAN system supports two crucial types of operations: Approach with Vertical Guidance (APV 1) and en-route (RNP 0.1).
  • APV 1 enables precise approaches, providing vertical guidance to pilots during landing procedures.
  • The en-route operation, known as Required Navigation Performance (RNP) 0.1, ensures accurate navigation during the aircraft’s flight between airports.
