1. A method of personal tracking, said method using a personal tracking system;

  • said system comprising at least one watson communication device and a base station;

    each said watson communication device having a watson ID-number;

    each said watson device including a position determining device, a receiver, a communication device, and a microprocessor;

    said base station including a computer, a modem, and a base station software (BSS);

    said BSS including a user interface, a central database, a non-volatile memory, a plurality of other applications, and a communications controller;

    said method comprising the steps of;

    sending each said watson ID-number to said base station by each said watson device;

    communicating the commands of said base station to each said watson communications device;

    determining the location of each said watson device;

    communicating the location of each said watson device to said base station;

    receiving the location of each said watson device by said base station;

    updating the data related to each said watson device in said non-volatile storage of said base station;

    displaying the location of each said watson device on a electronic map;

    said electronic map being a part of said base station software;

    changing the configuration of each said watson device by receiving commands and data from said base station by said communication means of each said watson device, by transmitting said base-station-commands and base-station-data to said microprocessor means of each said watson device, and by processing said base-station commands and base-station-data by said watson microprocessor;

    updating commands and data stored in said non-volatile memory by updating vehicle commands, wherein each said watson device is installed in the vehicle; and

    wherein the step of updating commands and data stored in said non-volatile memory of at least one said watson device further includes the step of receiving the route and the schedule information by at least one said watson device from said base station, and wherein at least one said watson device reports its adherence to or deviation from said received route and said received schedule to said base station.
