Abstract: PURPOSE: A code tracking apparatus and method are provided to obtain a gain in an auto correlation value by reducing the influence of signal interference. CONSTITUTION: A code tracking apparatus comprises a carrier wave I/Q mixer(210), a multi-path signal identifier(220), a separator(230), a correlate/integrator(240), and an discriminator(250). The carrier wave I/Q mixer multiplies an I-signal(In-Phase) and a Q-signal(Quadrature-Phase) in an input signal. The carrier wave I/Q mixer eliminates the carrier wave of the input signal. The multi-path signal identifier detects the location of a visible signal and the location of a multi-path signal in a signal in which the carrier wave is removed. The separator divides the multi-path signal from the input signal based on the location of the visible signal and the location of the multi-path signal. The correlate/integrator integrates a separated multi-path signal and a spreading and computes an integrated value. The discriminator detects the error value of code synchronization based on a correlation value and an integrated value.

Abstract: PURPOSE: A system and method for measuring an initial position using a pseudo satellite are provided to reduce the complexity of a system by measuring an accurate position indoors using only a GPS receiver. CONSTITUTION: A plurality of reference receivers(120) is installed in constant sections. The reference receivers estimate first measuring information from a received first pseudo satellite signal. A pseudo satellite(110) transmits a second pseudo satellite signal including the provided measuring information. A user receiver(130) estimates second measuring information from the received first pseudo satellite signal and extracts the first measuring information included in the received second pseudo satellite. The user receiver determines an initial position by analyzing the first measuring information and the second measuring information.
