マレーシア航空MH370便は今年3月8日未明に南シナ海南方にて消息を断ち、その行方は杳として知れない。乗客乗務員239名の運命は全く不明である。この事故の不運は飛行機の位置が地上側に全く未知であった事及び通信の途絶であった。この事故によって現在の洋上飛行航空機の追跡および通信システムに重大な欠陥がある事が明白になった。本論文は今回の悲惨な事故を二度と繰り返さないために(1) 洋上飛行中の旅客機に音声通信も可能な航空追跡通信測位システムを提供する。(2) そのために利用可能な全ての通信衛星システムを活用する。(3) 既存の衛星通信に与える特性劣化を最小化する(1.0dB以下)通信測位システムを提案するものである。 |

Malaysian Airways Flight370 (MH370) lost contact with the air traffic controllers on 8, March, 2014 and was never discovered since. The fate of the flight MH370 with 239 people onboard is totally unknown. The failure of the rescue operation is due to the lack of knowledge about the location of the aircraft after its last contact with the air traffic controllers. It is clear the existing aircraft tracking systems have serious defects. The GPS provides exact positioning tool for the mobile users but it was useless in this case because the communication links between the aircraft and ground controllers were lost.
The requirements for the desirable aircraft tracking system shall be (1) frequent exchanges of flight data , at least once every second, (2) Exact location determination with triangulation through more than 3 satellites or GPS, (3) Non-ceasing contacts during flights.
In reality we have many communication satellites in operation. Theoretically there are sufficient numbers of satellites for triangulation functions in many parts of the world. In order to use them for the aircraft tracking system, we need to add more requirements; (4) the newly added aircraft tracking system shall not inflict any serious degradation for the existing services.
This paper makes a proposal of a system that meets the above requirements and can also provide continuous communication links between aircrafts and air traffic controllers, which are broad enough to allow voices or even some video communications. |
