Abstract
A signal processing apparatus for a multi-mode satellite positioning system includes a band-pass filter, a local oscillator circuit, a first mixing circuit, a second mixing circuit, an analog-to-digital converter and a baseband circuit. By properly allocating a local frequency, radio frequency (RF) signals of a Global Positioning System (GPS), a Galileo positioning system and a Global Navigation System (GLONASS) are processed via a single signal path to save hardware cost.
