B. ADS-B
ADS-B (Automatic Dependent Surveillance–Broadcast) is an air traffic surveillance technology in which aircraft broadcast their position and other flight data via radio signals to improve tracking and situational awareness.
C. GAGAN
GAGAN (GPS Aided GEO Augmented Navigation) is India’s satellite-based augmentation system that enhances the accuracy and reliability of GPS signals for aviation and other navigation applications.
D. TACAN
TACAN is a military tactical air navigation system that provides aircraft with precise bearing and distance information to a ground station.
E. Differential GPS
Differential GPS is an enhanced positioning system that improves the accuracy of standard GPS signals by using ground-based reference stations to correct signal errors.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
