Summary: | The objective of the present invention is to provide a positioning device capable of quickly, reliably, and frequently correcting the position of the vehicle of the device, quickly and reliably detecting a mismatching state or an aberrant state, and correcting to the correct position. The positioning device is provided with: a GPS receiver (11) that receives transmission signals transmitted from a plurality of GPS satellites, and calculates a GPS position, which is the position of the vehicle of the device, on the basis of the transmission signals; a GPS position calculation unit (126) that calculates the pseudorange to each GPS satellite on the basis of the transmission signals, and calculates a GPS recalculated position, which is the position of the vehicle of the device, on the basis of the pseudoranges; and a multipass effect evaluation unit (128) that evaluates the effect of multipassing with respect to the GPS position on the basis of the difference between the GPS position calculated by means of the GPS receiver (11) and the GPS recalculated position calculated by the GPS position calculation unit (126).
La présente invention concerne un dispositif de localisation apte à corriger rapidement, de manière fiable et fréquemment la position du véhicule du dispositif, à détecter rapidement et de manière fiable un état de non concordance ou un état anormal et à corriger la position correcte. Le dispositif de localisation comprend : un récepteur GPS (11) qui reçoit des signaux de transmission transmis par une pluralité de satellites GPS et calcule une position GPS, qui est la position du véhicule du dispositif, sur la base des signaux de transmission ; une unité de calcul de position GPS (126) qui calcule la pseudo-distance de chaque satellite GPS sur la base des signaux de transmission et calcule une position recalculée GPS, qui est la position du véhicule du dispositif, sur la base des pseudo-distances ; et une unité d'évaluation d'effet de multipasse (128) qui évalue l'effet de multipasse par rapport à la position GPS sur la base de la différence entre la position GPS calculée au moyen du récepteur GPS (11) et la position recalculée GPS calculée par l'unité de calcul de position GPS (126). |
