Gps receiver and method for processing gps signals

GPS receiver according to the embodiment includes an antenna for receiving a GPS signal to an RF frequency from within the satellite clock; And it connected to the antenna, down converter for reducing the RF frequency of the received GPS signals to an intermediate frequency (IF); And it connected to the down converter, for sampling the IF GPS signals at a predetermined rate to produce sampled IF GPS signals digitizer; It is connected to the digitizer, and to store (a snapshot of GPS signals) the sampled IF GPS signal memory; And it is connected to the memory, in order to provide a pseudo distance information, and includes a digital signal processor (DSP) to perform on the IF GPS signals and operating under stored instructions sample the fast Fourier transform (FFT) operation. Also, typically, the operation includes a pre-processing and post-processing of the GPS signal. After the front end of the snapshot of the data acquisition receiver is down power. Also GSP receiver according to the embodiment includes other power management features, and in another embodiment, and includes the capability to correct for errors of the local oscillator is used to sample the GPS signals. Sensitivity of the calculation speed and calculation of pseudo range is improved by transmitting the Doppler frequency shift of the clock in the satellite to the receiver from an external source, such as a base station according to the embodiment of the invention.
