Navigation system for guiding a mobile body back and forth along the same route between two points
First Claim
1. A navigation system carried on a first mobile body, comprising:
- a time generating means for consecutively generating time data representative of time;
a first storing means for storing start position data of a start point and destination data of a destination as title data on a movement of the first mobile body, wherein time data is generated at a desired time interval while the first mobile body moves from the start point to the destination, and position data of a position and direction of the first mobile body at the time represented by the time data;
a second storing means for storing bi-dimensional position data on a map;
an operating means, wherein said operating means includes;
a time interval inputting means to enable an operator to define the desired time interval at which the position data of the moving mobile body is stored, anda first position inputting means to enable the operator to define start point and destination positions for the first mobile body so as to produce said first start position and destination data; and
a control means which is operative in response to both of said operating and time generating means for controlling said first and second storing means.

Abstract
In a navigation system, a controller includes a time selecting circuit for selecting times output from a timepiece in response to a signal representing a time interval from an operation unit, a satellite navigation position detecting circuit for receiving a radio wave at the times selected by the time selecting circuit from a Global Positioning System (GPS) receiver, and for determining the position of a mobile body on the basis of the radio wave, and an autonomous navigation position detecting circuit for receiving the output of both a distance sensor and an azimuth sensor which are synchronous to the times selected, for determining a distance and an azimuth based on the outputs of the distance and azimuth sensors, for determining a track of movement of the mobile body based on the distance and azimuth, and for adding the track to the start point of the mobile body to thereby produce the current position of the mobile body.
