Title:
DISTRIBUTED AND POLAR COORDINATE-BASED LONG-RANGE AND SHORT-RANGE MOBILE INTERACTIVE POSITIONING CAPABLE OF SETTING MEETING POINT
Document Type and Number:
WIPO Patent Application WO/2012/019557
Kind Code:
A1
Abstract:
The present invention provides a long-range distributed mobile interactive positioning method and system capable of setting a meeting point. Through positioning by a global positioning system, and through data exchange functions of a mobile communication network, a radio station, or the Beidou positioning system, positioning information between targets is transmitted in real time, thereby achieving interactive positioning. The direction of a target is determined through a method of radio direction and angle, and the distance of the target is determined through a method of radio strength, so that polar coordinates of the target are determined, a distributed position information data exchange center is formed, interactive polar coordinate-based positioning is realized, and the position is rectified by using a non-precision method. The method and the system can set one or more meeting points and meeting point tasks, and can perform task management. The method and the system can enable each moving target (person) to know positions of other moving targets (persons) before deciding a movement direction.
