  • Position Fixing By Use Of Radio Waves (AREA)

Abstract

PURPOSE:To easily device the present position against an area which has been divided by an absolute position by deriving whether position data whose position has been measured by a comparator exists in prescribed area data or not. CONSTITUTION:For instance, when a sensor is loaded on a vehicle and used for the purpose of a theft prevention of the vehicle, in case a driver leaves a stopped vehicle, a signal radio wave from a global position measuring system (GPS) is received 2 by operating an input device 6, position data for showing a stop position of the vehicle at that time point is inputted to a memory 3, and area data for showing a prescribed range from its position is stored. Thereafter, if a thief moves the vehicle, position data corresponding to a position variation of the vehicle is derived successively and the position data is compared with the area data by a comparator 4, and when the vehicle leaves the prescribed area, that is, when it is separated from the stop position by a prescribed distance, an alarm is raised from an alarm 5. In such a way, the present position against the area which has been divided by an absolute position can be judged exactly.
