Aircraft, as one of the important means of transportation, is an important field of Beidou application. In 2014, Malaysia Airlines' MH370 passenger plane lost contact with the control center. Because it did not send out specific location information and any emergency status information, it caused great difficulties in the search and rescue work of the aircraft and the investigation of the cause of the accident. Therefore, aircraft position monitoring and status management are extremely important to the safe operation of civil aviation. The short message function of Beidou satellite can provide an important technical means for building aircraft information and support systems.

The ground monitoring center obtains the current position information of the aircraft by analyzing the short message.

The shortcomings of the above-mentioned technical means mainly include the following two categories:

1. The Beidou airborne surveillance system will occupy the RDSS channel when using short messages for communication, resulting in temporary interruption of positioning data transmission.

2. The monitoring center cannot obtain the alarm status information of the aircraft in real time.
