My teachers, I want to know How do the GPS receiver receiver the sign @1572.42Mhz?By RLC resonant circiut? or others? Or the receive antenna resonance @1572.42 this frequency point? pls give me a hand! Tks!
The signal is received by means of a circularly polarized antenna; usually handhelds use an integrated patch antenna, however in general there are many types of antennas (e.g. quadrifilar, printed helical).
