  As shown in FIG. 2, first, the control unit 102 of the terminal device 100 receives the position information signal transmitted from the position transmission device (GPS satellite) 500 received by the reception unit 122 of the position acquisition unit 112 and the position acquisition. The change amount of the terminal device 100 detected by the unit 112 is transmitted to the information processing server 200 (step SA-1). Here, the control unit 102 may transmit accuracy information regarding the reliability (accuracy) of the position information signal acquired by the reliability evaluation unit 124 of the position acquisition unit 112 to the information processing server 200. In addition, indoors, position transmission device 500 may be a wireless LAN access point.

  And the arrangement | positioning information acquisition part 202a of the information processing server 200 acquires the arrangement | positioning information containing an azimuth | direction and an elevation angle regarding the arrangement | positioning of the GPS satellite 500 from the positional information signal transmitted from the terminal device 100 (step SA-2).

  Then, the positioning position information acquisition unit 202b of the information processing server 200 acquires positioning position information related to the positioning position of the terminal device 100 based on the position information signal transmitted from the terminal device 100, and stores the positioning position information in the positioning history database. It is stored as a positioning history in 206a (step SA-3). That is, the positioning position information acquisition unit 202b may hold the positioning position information as a trajectory.

  Then, the current position information acquisition unit 202d of the information processing server 200 calculates a DOP that is a precision reduction rate of the position information signal transmitted from the terminal device 100, and determines whether or not the DOP is a good value ( Step SA-4). For example, the current position information acquisition unit 202d may determine the positioning accuracy of the GPS module.

  When the current position information acquisition unit 202d of the information processing server 200 determines that the DOP of the position information signal is not a good value in Step SA-4 (Step SA-4: No), the process is performed in Step SA-. 12.

  On the other hand, when the current position information acquisition unit 202d of the information processing server 200 determines in step SA-4 that the DOP of the position information signal is a good value (step SA-4: Yes), the arrangement information acquisition unit 202a. The GPS satellite 500 whose elevation angle included in the arrangement information acquired by the above is higher than a threshold value is specified (extracted) (step SA-5). That is, the current position information acquisition unit 202d may determine the position of a single GPS satellite. Thus, the current position information acquisition unit 202d may determine whether to use the positioning position information for calculating the predicted position according to the satellite arrangement information.

  Then, the current position information acquisition unit 202d of the information processing server 200 determines whether or not three or more GPS satellites 500 whose elevation angle is higher than the threshold value can be specified (extracted) in Step SA-5 (Step SA-6). .

  Here, an example of a satellite having a high elevation angle in the present embodiment will be described with reference to FIG. FIG. 3 is a diagram showing an example of the satellite arrangement in the present embodiment.

  FIG. 3 is a conceptual diagram when the satellite arrangement centered on the positioning position is viewed from the sky. The satellite existing in the circle inside the elevation angle line (threshold) has a high elevation angle, that is, the positioning position. It indicates that the satellite is located near the head of. FIG. 3 shows that among satellites having a high elevation angle, satellite number 11 is arranged in the north, satellite number 1 is arranged in the west, and satellite number 32 is arranged in the southeast.

  Returning to FIG. 2, when the current position information acquisition unit 202d of the information processing server 200 determines in step SA-6 that three or more GPS satellites 500 whose elevation angle is higher than the threshold value cannot be specified (extracted) (step SA). −6: No), and the process proceeds to Step SA-12.

  On the other hand, if the current position information acquisition unit 202d of the information processing server 200 determines in step SA-6 that three or more GPS satellites 500 whose elevation angle is higher than the threshold value can be specified (extracted) (step SA-6: Yes). ) Calculate the S / N ratio of the position information signal transmitted from the terminal device 100, and identify (extract) the GPS satellite 500 whose noise is smaller than the threshold based on the S / N ratio (step SA-7). . That is, the current position information acquisition unit 202d may determine the reception accuracy of a single GPS satellite.

  Then, the current position information acquisition unit 202d of the information processing server 200 determines whether or not three or more GPS satellites 500 whose noise is smaller than the threshold value can be specified (extracted) in Step SA-7 (Step SA-8).

  When the current position information acquisition unit 202d of the information processing server 200 determines in step SA-8 that three or more GPS satellites 500 whose noise is smaller than the threshold value cannot be specified (extracted) (step SA-8: No). ), The process proceeds to step SA-12.

  When the current position information acquisition unit 202d of the information processing server 200 determines in step SA-8 that three or more GPS satellites 500 whose noise is smaller than the threshold value can be specified (extracted) (step SA-8: Yes). Based on the arrangement information acquired by the arrangement information acquisition unit 202a, the arrangement of the GPS satellites 500 is classified into four arrangement areas (northwest area, northeast area, southeast area, and southwest area) (step SA-9). ).

  Then, the current position information acquisition unit 202d of the information processing server 200 determines whether or not the GPS satellite 500 is arranged in three areas or two non-adjacent areas in Step SA-9 (Step SA-10). . That is, the current position information acquisition unit 202d acquires from the satellite arrangement information how to disperse a plurality of received satellites with respect to the area defined by the direction, and determines the positioning position information according to the disparity in the predicted position (current position). It may be determined whether or not to use for calculation of (position). As described above, the current position information acquisition unit 202d may determine the success or failure of the positioning position by analyzing under what circumstances the position is determined from the information of the GPS satellite 500. The four arrangement areas may be defined not only by azimuth but also by a predetermined number of areas defined from relative angles with one GPS satellite as a reference position.

  Here, an example of the satellite arrangement in the present embodiment will be described with reference to FIG. FIG. 4 is a diagram showing an example of the satellite arrangement in the present embodiment.

  As shown in FIG. 4, the inside of the elevation elevation line is divided into four areas (northwest area, northeast area, southeast area, and southwest area), and it is determined in which area the satellite is arranged. Good. Here, when the satellites are arranged in three areas or two adjacent non-adjacent (non-adjacent) areas, it may be determined that the satellites are scattered, and the others are regarded as being biased. . That is, a state in which the azimuth of the satellite with a high elevation angle is somewhat deviated is an ideal state for positioning. In addition, if past positioning draws a beautiful trajectory, even if satellites are arranged in two adjacent areas, the satellites are scattered (that is, GPS signals to be measured are valid). You may judge. Further, when the condition that the S / N ratio is large (= noise is small) is satisfied, it may be determined that the GPS signal is valid. In addition, if the S / N ratio of one of the satellites to be measured is small, even if there is no other satellite that fits inside the elevation angle high line, it is necessary that the past positioning draws a beautiful trajectory. In addition, the GPS signal may be validated by widening the elevation angle high line or relaxing the threshold of the S / N ratio. Also, if the position predicted from the past positioning and the positioning position are within a predetermined range, the GPS signal is enabled by widening the elevation high line or relaxing the S / N ratio threshold. Also good.

  Returning to FIG. 2, when the current position information acquisition unit 202d of the information processing server 200 determines in step SA-10 that the GPS satellite 500 is located in three areas or two non-adjacent areas (step SA). −10: Yes), the positioning position information acquired by the positioning position information acquisition unit 202b is acquired as the current position information of the terminal device 100 (step SA-11), and the process is terminated. The current position information acquisition unit 202d may transmit the acquired current position information to the terminal device 100. Then, the control unit 102 of the terminal device 100 may present the current position to the user of the terminal device 100 by causing the display unit 114 to display the received current position information. That is, step SA-11 is a process when it is determined that the GPS positioning position is valid.

  On the other hand, the current position information acquisition unit 202d of the information processing server 200 determines in step SA-10 that the GPS satellite 500 is not located in three areas or two non-adjacent areas (step SA-10: No), referring to the positioning history stored in the positioning history database 206a, it is determined whether or not the positioning position information acquired by the positioning position information acquisition unit 202b is consistent with the positioning history (step SA). -12). In other words, the current position information acquisition unit 202d may determine whether or not the position locus is wrinkled.

  When the current position information acquisition unit 202d of the information processing server 200 determines in step SA-12 that the positioning position information is not consistent with the positioning history (step SA-12: No), the process is performed. The process proceeds to step SA-20.

  On the other hand, if the current position information acquisition unit 202d of the information processing server 200 determines in step SA-12 that the positioning position information is consistent with the positioning history (step SA-12: Yes), the elevation angle information The threshold value and the noise threshold value are changed so as to be relaxed (step SA-13). That is, the current position information acquisition unit 202d refers to the past position measurement history, and relaxes the elevation angle and S / N ratio thresholds when the position measurement history satisfies a predetermined condition (when clean). You may do it.

  Then, the current position information acquisition unit 202d of the information processing server 200 identifies (extracts) a GPS satellite 500 whose elevation angle included in the arrangement information acquired by the arrangement information acquisition unit 202a is higher than a threshold value (step SA-14). .

  Here, the processing from step SA-15 to step SA-18 in the first embodiment shown in FIG. 2 is the same as the processing from step SA-6 to step SA-9 in the first embodiment shown in FIG. Since there is, explanation is omitted. However, when the current position information acquisition unit 202d of the information processing server 200 determines in step SA-15 that three or more GPS satellites 500 whose elevation angle is higher than the threshold value cannot be specified (extracted) (step SA-15: No) and when it is determined in step SA-17 that three or more GPS satellites 500 whose noise is smaller than the threshold value cannot be specified (extracted) (step SA-17: No), the process is not performed in step SA-12. Then, the process proceeds to step SA-20.

  Then, the current position information acquisition unit 202d of the information processing server 200 determines whether or not the GPS satellites 500 are arranged in two or more areas in Step SA-18 (Step SA-19).

  When the current position information acquisition unit 202d of the information processing server 200 determines in step SA-19 that the GPS satellites 500 are arranged in two or more areas (step SA-19: Yes), the processing is performed. Move to SA-11.

  On the other hand, when the current position information acquisition unit 202d of the information processing server 200 determines in step SA-19 that the GPS satellites 500 are not arranged in two or more areas (step SA-19: No), the process is performed. Move to SA-20.

  Then, the behavior information acquisition unit 202c of the information processing server 200 acquires the moving speed and the traveling direction of the terminal device 100 based on the change amount of the terminal device 100 transmitted from the terminal device 100 (step SA-20). .

  Then, the current position information acquisition unit 202d of the information processing server 200 includes the positioning position information acquired by the positioning position information acquisition unit 202b, the positioning history stored in the positioning history database 206a, and the terminal acquired by the behavior information acquisition unit 202c. Obtained by predicting the current position information of the terminal device 100 based on the moving speed of the device 100 and / or the traveling direction of the terminal device 100 obtained by the behavior information obtaining unit 202c (step SA-21). Exit. Here, the current position information acquisition unit 202d contributes (0% to 100%), which is a utilization ratio of using the positioning position information in the current position information prediction according to the evaluation of the arrangement of the GPS satellites 500 in the above process. And the current position information of the terminal device 100 may be predicted based on the degree of contribution. That is, the current position information acquisition unit 202d may predict the current position information of the terminal device 100 using the positioning position information according to the evaluation of the arrangement of the GPS satellites 500 performed in the above process. The current position information of the terminal device 100 may be predicted without using the information, and the current position information of the terminal device 100 is predicted by using the positioning position information with a predetermined weight (0% -100%). May be. As described above, the current position information acquisition unit 202d may dynamically change the positioning position success / failure determination condition based on the analyzed positioning situation and the position of the positioning position locus, and calculate the predicted position of the moving body. The current position information acquisition unit 202d may transmit the acquired current position information to the terminal device 100. Then, when the terminal device 100 performs autonomous navigation or the like, the control unit 102 of the terminal device 100 may cause the display unit 114 to display the received current position information. That is, step SA-21 may be processing when it is determined that the GPS positioning position is invalid, for example.
