PROBLEM TO BE SOLVED: To provide a calculating system of location for a moving object which is capable of determining passage through an intersection and calculating the location of the moving object by a simple algorithm, without using a camera and an image recognizing device. SOLUTION: The calculating system of the location of the moving object which is carried by the moving object and detects the location of the moving object is equipped with a receiving means which receives radio waves from a plurality of satellites circling the earth and an intersection determining means which determines whether or not the moving object passes through the intersection, based on the state of reception of the radio waves from the satellites in the receiving means.
