摘要： A GPS positioning method to obtain pseudorange between a receiver terminal and a satellite by capturing a portion of received satellite signals of a predetermined time duration. A predetermined number of first input signals, equivalent to 1-bit of navigation data, are obtained with various delays in the starting point of processing. The first input signals are synchronously summed up to obtain second input signals. A PN code replica (pseudopattern) prepared by the receiver terminal operates on the second input signals to detect the polarity of the navigation bits and correct the polarity of the bits so that the bit polarity of the second input signals are always positive. Synchronous summation is conducted on the resulting signals, which have been derived from the complete captured signal, and a correlation calculation is conducted on the obtained synchronously summed signal using a replica PN code prepared by the receiver terminal, the signal delay value is detected and pseudorange is obtained using the result of the correlation calculation.

摘要： A Global Positioning System carries out Doppler correction of a C/A code sequence after a frequency conversion, and calculates a pseudo range by performing correlation calculation between the C/A code, which is obtained by summing up the C/A code sequence beginning from a polarity inversion boundary determined at a correlation peak detecting step ST10, and a C/A code generated in a GPS terminal. When a received electric field detected by a received electric field intensity detector 11 is good, the current position is determined from the pseudo range and the navigation data extracted by the GPS terminal itself, whereas when the received electric field is poor, the current position is determined from the pseudo range and the navigation data sent from an external apparatus.

摘要： 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. Communication between a terminal and a base station is not always required for determining the position because the GPS terminal does not always obtain the Doppler information from the base station, reducing communication cost.
摘要翻译：全球定位系统（GPS）通过求和从相关峰值位置检测器确定的极性反转边界开始，构成每个位导航数据的PN帧中的相应位置处的码片构成C / A码序列; 通过计算C / A码序列与由GPS终端产生的参考C / A码序列之间的相关性来计算伪距离; 并使用伪距离和导航数据来确定GPS终端的位置。当接收到的电场强度检测器检测到的接收电场大于阈值电平时，使用GPS终端内检测的导航数据，当接收到的电场低于阈值时，使用从外部系统接收到的导航数据水平。因此，由于检测到导航数据的极性反转边界，所以要集成的PN帧的数量受到限制，因此灵敏度（S / N比）是足够的。由于GPS终端不总是从基站获得多普勒信息，因此终端和基站之间的通信并不总是需要确定位置，从而降低通信成本。
