GLOBAL POSITIONING SYSTEM
DEVICES
GPS is a positioning system based on
a network of satellites that
continuously transmit coded
information. The information
transmitted from the satellites can be
interpreted by receivers to precisely
identify locations on earth by
measuring distances from the
satellites.
13. DISCUSSION
Three Components of GPS
Space
User
Control
• Space Segment: the satellites
orbiting the earth and transmitting
timing and ranging messages
• Control Segment: monitors the
health and position of the satellites
in the space segment and transmits
correction information back up to
the satellites
• User Segment: The hand-held or
other receivers used to interpret the
messages broadcast from the
satellites
