Satellite navigation refers to positioning and location systems such as GPS that rely on radio signal timing and frequency measurements from orbiting satellites to determine a receiver's position on Earth. In the context of wireless sensing research, it matters because Doppler-induced frequency shifts in satellite signals introduce errors that must be modeled and compensated, particularly when the receiver or platform is in motion, directly informing how similar frequency-shift phenomena are handled in ground-based RF and CSI sensing systems. Key variants include GPS, GLONASS, Galileo, and BeiDou, which collectively form the broader category of Global Navigation Satellite Systems (GNSS).
