Abstract:
A high accuracy satellite signal receiving controller and associated method is provided. The high accuracy satellite signal receiving controller includes a frequency synthesizer, and an analog-to-digital converter (ADC), a Global Positioning System (GPS) receiving module and a control unit. The frequency synthesizer, coupled to an external non-temperature-compensated crystal oscillator (non-TXCO), generates an oscillating frequency signal to the GPS receiving module. The ADC converts an analog temperature signal into a digital temperature signal. The control unit, coupled to the ADC, adaptively updates temperature/frequency offset data.
