Wide Area Augmentation systems are mainly used in:
Show Hint
Whenever you see "Augmentation System" (like WAAS or EGNOS), think "GPS Corrector". It augments (improves) the GPS signal.

- GIS
- GPS
- RS
- TIN
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Standard Global Positioning Systems suffer from slight inaccuracies caused by atmospheric disturbances and orbital shifts.
Step 2: Meaning
A Wide Area Augmentation System (WAAS) is a network of ground-based reference stations created specifically to correct these inaccuracies.
Step 3: Analysis
• GIS (Geographic Information System): Software for managing spatial data.
• RS (Remote Sensing): Capturing data from a distance (like satellites or drones).
• WAAS was developed by the Federal Aviation Administration (FAA) specifically to augment the GPS (Global Positioning System). It sends correction data to GPS receivers, improving their accuracy from 15 meters down to about 3 meters.
Step 4: Conclusion
WAAS is an exclusive supplementary technology designed entirely to improve GPS functionality. Final Answer: (B)
