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 method of transmitting position data via cellular communication system includes the steps of receiving position data from a position data producer such as a GPS, an INS, or a GPS/INS integrated system, attaching the position data to a location registration data stream, and sending the position data along with the location registration data to a base station. This method takes advantages of the existing location updating procedure in a cellular network system to transmit precision position data of a mobile station. It does not need a dialing up to transmit position data. By utilizing this method, the position data of the mobile station can be delivered to the base station or cellular network whenever the mobile station is powered on.

Abstract: A processing method for motion measurement, which is adapted to apply to output signals proportional to rotation and translational motion of a carrier, respectively from rate sensors and acceleration sensors, is more suitable for emerging MEMS rate and acceleration sensors. Compared with a conventional IMU, the processing method utilizes a feedforward open-loop signal processing scheme to obtain highly accurate motion measurements by means of signal digitizing, temperature control and compensation, sensor error and misalignment calibrations, attitude updating, and damping control loops, and dramatically shrinks the size of mechanical and electronic hardware and power consumption, meanwhile, obtains highly accurate motion measurements.
