This invention is a wireless mobile indoor / outdoor tracking system. It is designed to track the absolute position of all nodes in a network indoors and outdoors. The system uses GPS positioning when a signal is available and RF ranging when it is unavailable. When indoors, a minimum of three network nodes must receive a GPS signal to determine absolute position. A mesh network is used to make the system mobile and to create an avenue for data to be transmitted to a remote base station.

A position information management system in which a portable remote terminal includes a plurality of kinds of positioning means for positioning based on a GPS, positioning based on a portable-telephone or PHS base station, positioning based on a radio marker, and independent positioning based on a direction detector, so that the holder of the portable remote terminal can be navigated anywhere. The holder of the portable remote terminal can know the position of a third party similarly holding such a portable remote terminal, by inquiring of a central system, and he / she can supervise, for example, the action of an old person, a child, or a skier in a skiing area. Further, only the map data of a district which is often used by the holder is stored in the portable remote terminal. In this regard, when the holder is in a district not contained within the retained map data, he / she downloads corresponding map data from the central system and uses the downloaded map data.

A method and apparatus to confine and constrain an animal or human subject to a specific area has the capability to change the borders of the restraint area remotely to maximize an area's utility. A collar or support is placed on the subject; the collar carries an electronic module to receive and send signals and to activate a restraining or feedback mechanism. In its simplest form, the collar receives and transmits Global Positioning System (GPS) data to be matched against a preset group of boundary coordinates. The system of the present invention utilizes GPS location technology to define the boundary. When the input matches the boundary coordinates set into the receiver, an impulse is delivered to the subject or wearer. This impulse becomes increasingly severe as the wearer moves farther away from the boundary point. Upon return to the boundary location the impulse ceases and, as long as the wearer stays within the boundaries, no further impulse is imparted. Terrain of the designated area is not a factor in the operation of the system since it can be programmed for use anywhere. The coordinates of the boundaries can either be preset or remotely changed to redefine the permitted areas.

GPS satellites are culled into a minimum, preferred group having a longest dwell time within a cone of space, and communicated to mobile devices or subscribers within a particular region (e.g., serviced by a particular base station). The culling may initially be a list of GPS satellites visible to a particular base station at a particular time. As a preferred culling, only those GPS satellites currently within a cone of space above the relevant base station are selected for communication by a mobile device within the service area of the relevant base station. As an ultimate culling, a minimum set of GPS satellites may be selected based on, e.g., being not only within an arbitrary cone of space normal to the base station, but also projected to remain within that cone of space for the longest period of time, i.e., having the longest dwell time.
