What type of navigation system uses satellites?

The correct choice involves the Global Positioning System (GPS), which is a satellite-based navigation system that provides accurate location and time information anywhere on Earth, regardless of weather conditions or time of day. GPS operates by using a constellation of satellites that transmit signals to receivers on the ground, allowing those receivers to triangulate their position by calculating the time it takes for the signals to arrive.

The distinguishing feature of GPS is its reliance on satellites in orbit to determine precise geographical locations, which is why it is the answer to this question. The system has become a fundamental tool in aviation, providing pilots and navigators with real-time data for enhanced situational awareness, route planning, and navigation assistance.

In contrast, an Inertial Navigation System relies on sensors to measure aircraft movement and calculate position based on initial coordinates without external references like satellites. A Radio Navigation System uses ground-based transmitters and receivers to determine position but does not harness the advantages of satellite technology. Standard Navigation Procedures refer to operating methods for navigation but do not specify a type of system and can include various disciplines that may or may not use satellite data.
