The document discusses the future development of air traffic control systems. It outlines how systems will transition from radar-based to satellite-based navigation to allow more direct flight paths and increased airspace capacity. NextGen will implement satellite technology by 2025 to guide aircraft with greater accuracy. This will help controllers manage the increasing number of flights and reduce delays by allowing planes to avoid weather and fly more direct routes.

3. Abstract
Air Traffic Control system has developed in
predecessor and it’s necessary to developed
this system to avoid air traffic collisions, I
displayed here in slides the system developed
stages and future of ATC system thru satellite .

4. Introduction
The United States air traffic control system is
safest in the world. Federal Aviation
Administration and its Air traffic organization
work continuously to improve the system.
The next generation will transform the national
airspace system from one that is based on
ground radars to one that uses satellite
technology.

5. ATC System development in future
NextGen will have the technology and infrastructure necessary to handle the increasing air traffic expected in
the coming decades. Satellite-based navigation will allow aircraft to fly more direct routes and navigate
around inclement weather which will increase airspace capacity and reduce delays.

6. There are around 7,000 aircraft in the air over the United States at any given time.

7. Major systems in development
• 120. Satellite system: a system using earth
satellites can provide worldwide navigation coverage
with the accuracy associated with line-of-sight
frequencies.
• 121. Microwave Landing System: More flexible
approach paths in while ILS has served well.
• 123. Collision-Avoidance System: Two aircraft
on parallel tracks may pass each other very closely.

8. The Airport as an operation system
• The airport as system
Airport forms an essential part of the air
transport system. therefore, the point of
interaction of the three major components of
the air transport system:
The airport, including for these discussion
purpose the airways control system – The
airline – The user.

Stanton, and Clifton Moore , chapter 1,Table 1.1
The diagram attempts to show how these interactions produce the prime parameters of operational
scale. Passenger demand , airport capacity, and flight capacity.

10. System development of ATC:
• Stage 1 : Procedural ATC System
Stage 1 ATC system use procedural method, they
requires - flight plan - paper strips - radio
system.
• Stage 2: Procedural ATC with radar assistance
In 1960s ATC began to use radar with
surveillance approach radar (SAR). Radar
could be use to monitor aircraft thru
Instrument landing system (ILS).

11. • Stage 3: The first-generation “automated”
ATC system.
Radar and computer, radar provide real-time
surveillance within ATCC.
• Stage 4: Current generation radar and
computer-based ATC system.
A modern automated ATC system is illustrated,
with tactical and strategic controllers on
modern flight deck.

The FDP and RDP functions of the generation have had flow management processor (FMP) capability integrated,
and support – information system (SIS) processing function also integrated.

13. Conclusions
As FAA moved transition of ATC system from
radar-based to satellite based. controllers and
pilots will have the advantage of this
technology.
Satellite-Technology will allow controllers to
guide aircraft in more direct routes through
the nation's airspace.
