摘要： A positioning apparatus includes a correlator 30 for calculating a correlation between the pseudo pattern code of each of satellites 1 and 2 and each of SPS signals associated with the satellites 1 and 2, and for outputting a correlation value indicating the correlation, sets up effective ranges δ1 and δ2 for the correlation values outputted from the correlator 30 on the basis of a pseudo distance PR1 between the satellite 1 and a SPS reference station 4, and a pseudo distance PR2 between the satellite 2 and the SPS reference station 4, and detects peak values which fall within the effective ranges δ1 and δ2, respectively. As a result, the positioning apparatus can determine the current position correctly even under a receiving environment in which the electric waves directly from the satellites 1 and 2 may become weak.

摘要： To propose a communication device capable of easily calibrating frequency error and obtaining position information with high accuracy. The communication device includes a frequency error detecting circuit that receives a reception signal, detects frequency error contained in the reception signal, and generates frequency error correction output, main frequency error correcting means that corrects the frequency error contained in the reception signal based on the frequency error correction output, and main correlation calculating means that performs calculation of correlation between reception output which frequency error has been corrected by the main frequency error correcting means and a pseudo random noise code, and a data processing circuit that outputs position information with respect to the radio wave source based on the output from the main correlation calculating means.
