Airplane monitor system and method on the basis of real-time dynamic positioning and data link

Abstract

The invention relates to an airplane monitor system and method on the basis of real-time dynamic positioning and data link. The system comprises an airborne device and a ground-based device. The airborne device is installed on an airplane and is used for receiving satellite signals and real-time differential update information, finishing the correction of airplane positioning data, and sending differentiated position information in real time; the ground-based device is installed on the approach tower and is used for receiving the real-time differential update information, sending the update information to airplanes in the airspace of the airport periodically, receiving differential positioning data sent in real time by airplanes in the air, and sending the received airplane position information to an flight monitor terminal. By use of the system and method, the safety factor of flight training and monitor level of the stage of airplane approaching landing are increased; The system and method can be applied in flight conducting and air traffic control. Position information of targets in the airspace of the airport can be monitored in real time. The system and method can be applied in flight conducting and guiding, especially in dangerous cases such as rough weather and decreasing visibility, providing auxiliary decision-making information for flight commanders, and increasing the safety factor of flight training.

Description

technical field [0001] The invention relates to an aircraft approach monitoring system and method. Background technique [0002] During flight training, the whole process from the crew entering the aircraft, the preparation of the aircraft to the landing and rolling deceleration until all the people on board leave the aircraft is a complicated flight process. In this process, the aircraft will face a series of flight safety test issues. Among them, the approach and landing of the aircraft have high requirements on the accuracy of the aircraft's speed, altitude, and orientation. lead to security problems. Especially when there are dangerous situations such as weather deterioration and rapid decrease in visibility during flight, the flight commander cannot effectively grasp the flight situation in the flight airspace. [0003] However, the existing monitoring methods rely on radar plotting to grasp the flight status of the aircraft. This method transmits less information, p...

Among them, the approach and landing of the aircraft have high requirements on the accuracy of the aircraft's speed, altitude, and orientation. lead to security problems

Especially when there are dangerous situations such as weather deterioration and rapid decrease in visibility during flight, the flight commander cannot effectively grasp the flight situation in the flight airspace

[0003] However, the existing monitoring methods rely on radar plotting to grasp the flight status of the aircraft. This method transmits less information, poor real-time performance, and low accuracy, which is not conducive to the flight commander's real-time grasp of the flight status of the aircraft in the air, and cannot solve complex weather conditions.
