GPS aircraft tracking allows planes equipped with GPS receivers to be monitored in real-time. GPS was developed in 1973 by the U.S. Department of Defense to improve navigation and originally used 24 satellites. The GPS system has three components - the space segment with over 30 satellites in orbit transmitting navigation signals, the control segment which monitors the system, and the user segment comprising thousands of military and civilian users. Aircraft equipped with ADS-B transmit position, speed, direction and altitude to satellites every 15 minutes, which relay the information to ground stations for processing and display of the plane's location.

Tracking

2. What does mean by
GPS in Aircraft
GPS aircraft tracking is a means of tracking the
position of an aircraft fitted with a GPS receiver. By
communication with GPS satellites, detailed real-
time data on flight variables can be passed to a
server on the ground.

3. History of GPS in Aircraft
01 The GPS project was developed in 1973 to overcome the limitations
of previous navigation systems.
02 GPS was created and realized by the U.S. department of defense and
was originally run with 24 satellites.
03 GPS was first used on February 16, 1994 in Aircraft

4. 01 Space Segment
02 Control Segment
03 User Segment
Components in GPS
The GPS system has three components: The space
segment, control segment, and user segments.

5. Space Segment
24 decommissioned
satellites
24%
01 Minimum of 31 satellites in orbit around earth at altitude 20,000 km.
02 It transmit radio-navigation signals, and store and retransmit the
navigation message sent by the control segment.
4 view point
satellites
4%

6. Control Segment
01 Combination of a master control station, 12
ground antennas, and 16 monitoring stations
responsible for the proper functioning of all the
operation of GPS such as changing unhealthy
satellite with a healthy one

7. User Segment
01 Comprises of thousand of U.S. and military
users who uses the secure GPS precise
Positioning service, and millions of civil,
commercial and scientific users .

8. How GPS works in
Aircraft
Aircraft ADS-B enabled sends its information
to the orbiting satellites after every 15 minutes.
01
Message from aircraft caring the in formation
its exact position, air speed, direction and
altitude is sent to the satellite.
02
Satellite receive this information and
rebroadcast to the nearest ground receiver
station.
03
Ground receiver receive this information and pass
it to the control station using optics cabling.
04
The control system process this information to
track the actual position of the aircraft and
update on screen board.
