    摘要: A location estimating apparatus 10 has an information acquiring part 12, an information storing part 18, and an arithmetic processing part 20. The information acquiring part 12 has a location information acquirer 14 for acquiring location information of a mobile object from information, and an error information acquirer 16 for acquiring error information from information. The information storing part 18 stores the location information and error information sent from the information acquiring part 12, at each measurement time. The arithmetic processing part 20 estimates a location from the location information and error information from the information acquiring part 12. The arithmetic processing part 20 of the location estimating apparatus estimates the location of the mobile object by successively executing a first step of estimating a moving area per unit time of the mobile object, a second step of estimating an existing area at present of the mobile object, and a third step of estimating a location at present of the mobile object. This makes it feasible to provide location estimating means capable of achieving a high matching rate with an actual state, without use of other device information, while effectively utilizing information.
