         5 . A position information processing apparatus comprising:
 a receiving device that receives a signal including a satellite signal;   an accepting device that repeatedly acquires sequential information including a plurality of recording target information changeable with time, including position information obtained using a signal received by the receiving device; and   a recording device that correlates and records the accepted sequential information with time information,   wherein the accepting device records information relating to the satellite signal used as a basis of an operation of the position information and provides the information for authentication processing, and   the accepting device detects a signal with a predetermined PRN-ID from the signals received by the receiving device,   when a plurality of signals with the same PRN-ID are detected in a one-time detection performed by the accepting device, the accepting device generates a reference signal on the basis of each of the plurality of signals, acquires and accepts two or more pieces of position information on the basis of the generated reference signal and the signal received by the receiving device,   when a single signal with the same PRN-ID is detected in the one-time detection performed by the accepting device, the accepting device acquires position information, and   when two or more pieces of the position information relating to mutually different positions are obtained, the recording device records the obtained position information indicating the mutually different positions.   
     
     
         6 . The position information processing apparatus according to  claim 5 , further comprising
 a selecting and outputting device that, when the recording device records the two or more pieces of the position information relating to the mutually different positions, selects and outputs probable information from the recorded position information.   
     
     
         7 . A position information processing apparatus comprising:
 a receiving device that receives signals including a satellite signal;   an accepting device that repeatedly accepts sequential information including recording target of information changeable with time, and including position information obtained using the received satellite signal, the accepting device detects a signal with a predetermined PRN-ID from the signals received by the receiving device, and when a plurality of signals with the same PRN-ID are detected in a one time detection performed by the accepting device, the accepting device generates a reference signal on the basis of each of the plurality of signals, and acquires and accepts sequential information including two or more pieces of information indicating mutually different positions on the basis of the generated reference signal and the signal received by the receiving device, and when a single signal with the same PRN-ID is detected in the one-time detection performed by the accepting device, the accepting device acquires position information on the basis of a reference signal generated based on the single signal and the signal received by the receiving device; and   a recording device that correlates and records the accepted sequential information together with time information, and when, in the one-time detection, two or more signals with the same PRN-ID are detected in the signals received by the receiving device the receiving device records information indicating that signals other than the satellite signal may be included in the received signals in correlation with the sequential information.
