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.

High accuracy satellite receiving controller and associated method

A GPS data recording apparatus includes a storage device and a processing circuit coupled to the storage device. The processing circuit comprises: a sampling module, for sampling a GPS data; and a packet processor, for packetizing the sampled GPS data to generate a data packet to be stored in the storage device, and for unpacketizing the stored data packet from the storage device if necessary. According to present invention, GPS data can be recorded and be replayed as necessary.
