Abstract
A hybrid Global Positioning System (GPS) receiving method, and associated GPS receiving apparatus is provided. The GPS receiving apparatus includes an RF front-end circuit, a correlation circuit, an acquisition engine and a bidirectional interface control unit. The RF front-end receiving circuit receives a satellite signal and converts the same into a baseband signal. The acquisition engine, coupled to the correlation circuit, determines reception power of the GPS satellite signal. The interface control unit, coupled to the acquisition engine, provides a low-speed interface for transmitting GPS intermediate data that includes a code bin, a frequency bin, navigation data, a local system time and a GPS time. The interface control unit includes a memory interface unit for coupling to a memory.
