How GPS Receivers Work – Trilateration vs Triangulation

Websignal—A natural or artificial object or structure located at or near a survey station and used as a sighting point or target for survey measurements signal, aerial—A guyed, balloon-suspended target for taking sights on points that cannot be seen from triangulation stations; particularly useful when locating points required for the control of aerial surveys. WebFortunately, there are factors that distinguish reflected multipath signals from direct, line-of-sight, signals. For example, reflected signals at the frequencies used for L1, L2, and L5 tend to be weaker and more diffuse than the directly received signals. Another difference involves the circular polarization of the GPS signal.
