摘要： A navigation system which can enhance the position determining accuracy of a mobile object without employing any high precision measuring instrument. The navigation system comprises a GPS range measuring device (101 in Fig. 1), an angular velocity measuring device (102), a velocity measuring device (103) and an azimuth measuring device (104), which measure the motion of the mobile object; a GPS range error estimating device (105), an angular velocity error estimating device (106), a velocity, error estimating device (107) and an azimuth error estimating device (108), which estimate errors involved in the respectively corresponding measuring devices; and a position calculating device (109) which calculates the position of the mobile object from the outputs of the error estimating devices. The error estimating devices are implemented by Kalman filters and averaging processes. The factors of the errors of the individual measuring devices are assumed, and the outputs thereof are corrected, so that the position of the mobile object can always be determined at a high accuracy without employing any high precision sensor.

摘要： A map display method and a medium storing program for realizing this method, and a map display apparatus are described wherein map information in an area specified in response to a current location of a moving object is read from a map database. Furthermore, a perspective map looking from a view point toward a ground plane is generated by executing coordinate transformation procedures on said map information, and a scenery image corresponding to said perspective map is displayed on a display device. According to the invention said view point for generating said perspective map is established above a height of a map constituent element existing at a location specified in response to the current location of said moving object, said height of said view point being renewed with movement of said moving object. Additionally, a navigation system is described comprising a map database device for storing map information at least including information regarding topographical features and roads. Information regarding heights of map constituent elements are obtained from a map database storing map information.
