Airborne Internet….SATS and Beyond
Mobile connectivity is a growing technology in our society today. Its growth is
fueled by the desire of people to remain connected to "the network" even while
traveling. From wireless LANs at home and the office to wireless connectivity
with Personal Digital Assistants (PDAs), people are utilizing new methods to
extend the traditional network connectivity that originated with a wire to a
computer.
The idea of using these same mobile connectivity principles has found its way
into aviation…and is being applied to comm, nav. & surveillance functions.
The concept of basic network connectivity could be used to connect other mobile
vehicles, including automobiles, trucks, and trains. Network connectivity could be
obtained between vehicles and a ground network infrastructure, thus enhancing
their ability to process data relative to their operation.

The Small Aircraft Transportation System is a safe travel
alternative, freeing people and products from transportation
system delays,
by creating access to more communities in less time.
The idea of an Airborne Internet was produced as a result of NASA's Small
Aircraft Transportation System (SATS) program planning. The SATS program
needed Airborne Internet to accomplish its performance goals. Program
planners identified the need to establish a robust communications channel
between aircraft and the ground network. But the utility of Airborne Internet
has the potential to extend beyond the SATS program.....It could open up a
whole new set of operating capabilities, safety and efficiency for tomorrow’s
transportation industry.
The Genesis of an idea……Airborne Internet

SATSLabs and A.I.
•Each SATSLab has some level of interest in A.I.
• The level of interest in A.I. Varies between the Labs

SATS Operational Capabilities
To Be Demonstrated in 2005
Higher Volume Operation at Non-Towered/Non-Radar Airports.
Enable simultaneous operations by multiple aircraft in non-radar
airspace at and around small non-towered airports in near allweather.
Lower Landing Minimums at Minimally Equipped Landing
Facilities
Provide precision approach and landing guidance to small airports
while avoiding land acquisition and approach lighting costs, as
well as ground-based precision guidance systems such as ILS.
Increase Single-pilot Crew Safety and Mission Reliability.
Increase single-pilot safety, precision, and mission completion
En Route Procedures and Systems for Integrated Fleet Operations.
Provide simulation and analytical assessments of concepts that
integrate SATS-equipped aircraft into higher en route air traffic
flows and controlled airspace.

Airborne Internet….Beyond SATS
…..and out into the horizon
•
Why should A.I. Be limited to SATS?
• SATS will receive greater benefit from A.I.
development and application if A.I. is expanded
beyond the realm of SATS
•
Why should A.I. be limited to General Aviation?
•
Why should A.I. be limited to Aviation?
• Other modes have the potential to benefit: railroad,
automobile/truck/highway, maritime
•
The greater the interest in the development of A.I., the
greater the benefit to all
AC_NET7.ppt
Why an Airborne Internet Forum?
•
Leverage resources.
•
Join our common interests to form a greater whole
•
Establish a legal entity for possible funding of A.I.
development
•
Collaborate to produce guidelines and standards
that will provide a roadmap to FAA certification
(GS&Cs)
•
Individual contributors to this process will enjoy
possible early business opportunities in A.I.

Airborne Internet has the potential for greater impact in aviation
AC_NET7.ppt
A.I. Application Example:
Surveillance Radar Augmentation
A/C tracking depends on secondary surveillance radar
Transponders in A/C reply to
ground interrogations from
surveillance radars. ATC has
positive knowledge of A/C
position, altitude, etc.
Outside of radar coverage
ATC has no positive
knowledge of A/C position,
altitude, etc.
- Use checkpoint reporting
Current System:
Radar dependant
airspace. Radars are
installed as airspace
traffic density increases
(e.g. NE U.S.)

Goal
Limitations:
-Provide aircraft altitude,

-Flight coverage is
geographic dependant
- Low altitude gaps
-Many GA airports not
