| Abstract(in English) | 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. |
