How GNSS Positioning Calculation Method Determines Location Using Satellite Signals
By intersecting these distances mathematically, the receiver pinpoints its exact location in three-dimensional space. Finally, "Satellite System" highlights the method, which relies on a network of artificial satellites transmitting microwave signals to ground-based receivers.
Global systems are designed to provide coverage across the entire planet, whereas regional systems optimize accuracy and performance within specific continents or countries. Unlike a single system operated by one nation, the term encompasses multiple international constellations, creating a layered and resilient ecosystem for precise positioning.
