Which navigation system utilizes satellites for determining aircraft position?

• A. Inertial Navigation System
• B. Global Positioning System (GPS)
• C. VOR Navigation System
• D. Ground-Based Navigation System

Answer: (B)

The Global Positioning System (GPS) is the correct answer because it is a satellite-based navigation system that triangulates the position of an aircraft using signals from multiple satellites orbiting the Earth. GPS provides precise location data, allowing pilots to determine their exact position in terms of latitude, longitude, and altitude. The system is effective in all weather conditions and is widely used for both en-route and approach navigation. In contrast, the Inertial Navigation System relies on internal sensors to calculate the position and movement of the aircraft based on its initial starting point and does not use satellite data. VOR (VHF Omnidirectional Range) Navigation System utilizes ground-based radio signals to provide lateral guidance, but it does not involve satellite technology. Ground-Based Navigation Systems generally include a variety of traditional navigation aids that work off fixed locations on the ground, failing to rely on satellites for position determination.
