Abstract. The Airborne Internet is envisioned to be a large scale multihop wireless mesh network of civil aviation aircraft connected via long range. The Airborne Internet is a proposed network in which all nodes would be located in .. 8. ciulamuhabal.ga?arnumber= Airborne Internet, Ask Latest information, Abstract, Report, Presentation (pdf,doc, ppt),Airborne Internet technology discussion,Airborne Internet paper.
Further to this providing a robust, fast and reliable connectivity network to the people on the go in vehicles and even aircraft is a challenge. In this paper we explore such a technology that talks about connectivity in aviation and aircrafts i. Airborne Internet. The idea is to take all the facilities and implementation of the ground networks and provide a high speed network connecting aircraft and ground. Published in: Persistent Link: The applications are designed around the Internet Protocol IP standard to take advantage of the existence of the network connection to the computer.
Airborne Internet is built upon the same model.
By combining application and data functionality over a common data channel, aviation has the potential to significantly reduce costs for equipage on the ground and in the aircraft.

In addition to defining the functional and physical relationships between system components, an architecture often provides design guidance in an attempt to achieve other desirable objectives such as efficient resource utilization, incremental development, verifiability, use of COTS products, ease of maintenance, and system extensibility. Developing a SATS Airborne Internet architecture consists of the following steps: 1 2 3 4 5 Understand the SATS operational concepts Define system level requirements Investigate and evaluate the external environment Identify trends and issues that must be addressed Apply modern system design techniques, i.
It is more a new way of thinking about air transportation than a technical concept that beckons to be explored. This leads to a variety of definitions of what SATS is or should be. To bound the AI architecture problem, we developed a set of system operation assumptions.
A sampling of these key assumptions are listed below: Pilot Until such time as highly automated systems can be fully tested and certified, SATS aircraft will have at least one qualified, instrument rated pilot on board.
Because of the level of automation on board, the SATS system will enable this pilot to be much more proficient and able to fly in nearly all weather conditions into a large number of minimally equipped airports. Avionics in addition to the minimum set of avionics required of normal IFR1 aircraft, SATS aircraft will have on board additional avionics equipment to enable the pilot to operate in near all-weather situations.
If SATS is to be prototyped in and operational in , this equipment will need to be compatible with systems used by commercial and general aviation airports to not require expensive new ground support systems not currently planned by the FAA.
Flight rules to meet its objectives, SATS aircraft will need to be able to access small and medium sized airports. Define system level requirements Specific, verifiable requirements for a SATS communications system must be developed.
The communications system is unique in that it is both an end system and an enabling infrastructure. As an end system it must provide pilot-controller, pilot-pilot, and pilot-flight operations communications. As an enabling infrastructure it must support applications associated with navigation, surveillance, and other functions.
Requirements need to be developed in the traditional areas of communication, navigation, and surveillance, including both avionics and ground infrastructure, consistent with the infrastructure defined in the task below. Other requirements will include support for passenger support systems Investigate and evaluate the external environment SATS, although a revolutionary transportation concept will have to work within the National Airspace System NAS.
This is true both during SATS prototyping in and during full-scale development, in This can be very tricky as the NAS is subject to many forces that are political, not technical, and as such is difficult to predict. For example, there are currently three competing communication technologies to provide aircraftaircraft position reporting.
Clearly, there is agreement that position reporting is desirable, but which technological approach will survive is like trying to choose between VHS and Betamax before the marketplace has spoken. We present a summary of some of the trends and issues in the next section of this paper.
Apply modern system design techniques SATS presents an ideal opportunity to apply object-oriented design techniques for the collection, analysis and documentation of system architecture. An antenna tracking unit uses a pilot tone transmitted from the Communications Payload to point the antenna toward the airborne platform. Although the MMW transceiver is broadband, it typically will only process a single 40 MHz channel at any one time.
The particular channel and frequency is determined by the NIU. The subscriber equipment can be readily developed by adapting from existing equipment for broadband services. The NIU comprises an L-band tuner and down converter, a high-speed up to 60 Mbps demodulator, a high-speed modulator, multiplexers and demultiplexers, and data, telephony and video interface electronics.
Each user terminal will provide access to data at rates up to In some applications, some of this bandwidth may be used to incorporate spread spectrum coding to improve performance against interference in this case, the user information rate would be reduced. The electronics for the RF data signal would be identical if the same frequency band is utilized.
The CPE, whether delivered or downloadd through a retailer, is designed for rapid installation and ease of use. NASA and AeroVironment are working on a solar-powered, lightweight plane that could fly over a city for six months or more, at 60, feet, without landing.
