  • Patent number: 7764227
    Abstract: 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 ?1 and ?2 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 ?1 and ?2, 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.

  • Patent number: 6437736
    Abstract: A Global Positioning System forms a C/A code sequence by summing up, beginning from a polarity inversion boundary determined by a correlation peak position detector, chips at corresponding positions in PN frames constituting each bit of navigation data; calculates pseudo ranges by computing correlation between the C/A code sequence and a reference C/A code sequence generated by a GPS terminal; and determines the position of the GPS terminal using the pseudo ranges and navigation data. The navigation data detected inside the GPS terminal is used when a received electric field detected by a received electric field intensity detector is greater than a predetermined level, and the navigation data received from an external system is used when the received electric field is below the predetermined level.

  • Patent number: 6297770
    Abstract: A Global Positioning System (GPS) forms a C/A code sequence by summing, beginning from a polarity inversion boundary determined by a correlation peak position detector, chips at corresponding positions in PN frames constituting each bit of navigation data; calculates pseudo ranges by computing correlation between the C/A code sequence and a reference C/A code sequence generated by the GPS terminal; and determines the position of the GPS terminal using the pseudo ranges and navigation data. The navigation data detected inside the GPS terminal is used when a received electric field detected by a received electric field intensity detector is greater than a threshold level, and the navigation data received from an external system is used when the received electric field is below the threshold level. Thus, the number of PN frames to be integrated is limited because the polarity inversion boundaries of the navigation data are detected, and hence the sensitivity (S/N ratio) is sufficient.
