Carrier Phase Measurement

Carrier phase measurement is a technique used in satellite-based positioning systems to determine precise locations. It involves analyzing the carrier wave—a high-frequency signal transmitted by satellites—to measure the exact number of wave cycles between the satellite and the receiver. By counting these cycles and measuring their phase, the system can calculate the distance with very high accuracy. This method improves positioning precision compared to simpler range measurements, enabling applications like surveying, geodesy, and advanced navigation, where understanding exact locations is crucial.
