Abstract: A method and system for multi-tracking among independent individuals without a monitoring center, where an individual is a person, a vehicle, or any other property, enables the individuals to be networked in a group and each individual to search and track other individuals of interest. The portable multi-tracking system is also capable of tracking personnel inside a building, where a self-contained positioning device 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 data to improve the accuracy and robustness of the positioning services. Thus the present invention provides excellent position tracking outside a building.

Abstract: A filtering mechanization method is provided for integrating a Global positioning System receiver with an Inertial Measurement Unit to produce highly accurate and highly reliable mixed GPS/IMU position, velocity, and attitude information of a carrier. The GPS filtered position and velocity data are first individually used as measurements of the two local filters to produce estimates of two sets of the local state vector. Then, the estimates of the two sets of local state vectors are mixed by a master filter device to produce global optimal estimates of master state vector including INS (Inertial Navigation System) navigation parameter errors, inertial sensor errors, and GPS correlated position and velocity errors. The estimates of the two sets of local state vector and master state vector are analyzed by a GPS failure detection/isolation logic module to prevent the mixed GPS/IMU position, velocity, and attitude information from becoming contaminated by undetected GPS failures.
