`
`Referring to FIGS. 1 to 12, a portable multi-tracking
`method and system according to a preferred embodiment of
`the present invention is illustrated, which is provided for
`multi-tracking processing by using a public network Such as
`the Internet, where the Internet is responsible for location
`and command data exchanging between individuals among
`a group. The individual is a person, a vehicle, or any other
`property. With this system, the individuals are networked in
`a group, and each individual can search and track other
`individuals of interest. The present invention also is
`equipped with a powerful self-contained micro IMU (Iner
`tial Measurement Unit), which is capable of tracking per
`sonnel inside a building, where the micro IMU provides
`continuous carrier's position information. In the open area a
`GPS (Global Positioning System) unit is activated to provide
`precision absolute position data which can be blended with
`the self-contained micro IMU data to improve the accuracy
`and robustness of the positioning services. Thus the present
`invention provides excellent position tracking outside a
`building.
`The IMU/GPS integrated device, in general, is costly and
`big in size. Weight, and large size lead to a not feasible
`deployment in a car or for being carried by a single indi
`vidual. With the emergence of the MEMS (MicroElectron
`icMechanical System) technology, a miniature IMU based
`on MEMS technology becomes an embracible reality.
`The micro IMU to be embodied in the preferred embodi
`ment of the present invention is invented by the applicants,
`referring to U.S. patents pending, “MicroElectroMechanical
`System for Measuring Angular Rate’, Ser. No.: 60/154,700;
`“Processing Method for Motion Measurement'. Ser. No.:
`09/399,980; “Angular Rate Producer with MicroElectroMe
`chanical System Technology', Ser. No.: 09/442,596; and
`“Micro Inertial Measurement Unit, Ser. No.: 09/477,151.
