The present invention is directed to an electronic system and method for managing
location, calendar, and event information. The system comprises at least two hand
portable electronic devices, each having a display device to display personal profile,
location, and event information, and means for processing, storing, and wirelessly
communicating data. A software program running in the electronic device can receive
local and remote input data; store, process, and update personal profile, event,
time, and location information; and convert location information into coordinates
of a graphic map display. The system additionally includes at least one earth orbiting
satellite device using remote sensing technology to determine the location coordinates
of the electronic device. The electronic devices receive synchronization messages
broadcast by the satellite device, causing the software program to update the personal
profile, event, time, and location information stored in each hand portable electronic device.
