ABSTRACT:
A location detecting system comprising a sensor unit, a main body having an operating mode consisting of a traveling mode and an simulation mode and including location detecting unit for calculating a current location of a moving body on the basis of data sensed by the sensor unit and further including a navigation controller connected to the location detecting unit, a change-over unit for changing over the operating mode to the traveling mode or the simulation mode, a storage unit detachably connected to the main body, a write unit for storing the data sensed by the sensor unit into the storage unit when the storage unit is connected to the main body and also the main body is in the traveling mode, and a read unit for inhibiting the data sensed by the sensor unit from being supplied to the location detecting unit and instead supplying the data stored in the storage unit to the location detecting unit, when the storage unit is connected to the main body and also the main body is in the simulation mode.
