Personal Computer with Integrated Global Positioning System

      Disclosed is a portable personal computer integrated with a
global positioning system to provide the location of the user,
together with local maps and other data which may be generated using
software stored in the computer.  Convenient attachment hardware and
interconnections form an integrated system from various component
parts.

      Fig. 1 shows the system in a configuration in which it may be
easily carried, while Fig. 2 shows the system of Fig. 1 opened into
an operational configuration.  Referring to Figs. 1 and 2, the system
includes a portable personal computer 10, global positioning
electronic unit 12, and an associated antenna unit 14.  Computer 10
is opened for operation by rotating an upper portion 16 upward,
exposing keyboard 18 and a display screen (not shown) within upper
portion 16.  Antenna unit 14 is mounted to upper portion 16 of
computer 10 by means of a hinged bracket 20, which may be manually
rotated to hold antenna unit 14 in a horizontal operational position.

      In operation, the antenna within unit 14 is aimed at multiple
navigational satellites.  In the version of Figs. 1 and 2, a short
range radio link is provided between antenna unit 14 and global
positioning electronic unit 12, which is in turn connected to
computer 10 by means of a cable 22 plugged into a port connector,
such as an RS-232 interface, at the rear of computer 10.  Global
positioning electronic unit 12, together with computer 10, calculates
the geographical location of antenna unit 14 based on the measured
locations of various navigational satellites relative to unit 14.
