Border-crossing efficient monitoring method for navigable aircraft based on position time-distance stratification

Abstract

The invention discloses a border-crossing efficient monitoring method for an aircraft based on compressive time and position stratification, and particularly suitable for no-fly-zone border-crossing automatic monitoring for the aircraft based on satellite navigation positioning and monitoring. The border-crossing efficient monitoring method comprises the steps that formatting processing is performed on a horizontal coordinate on the border of the no-fly zone according to set distance dimensions; the aircraft obtains self position data through a satellite navigation system, and transmits the position data to a ground monitoring center through a data communication link; the monitoring center performs format conversion and calculation on the aircraft position data according to a method based on time and distance stratification, and if the time is greater than a set value, border-crossing determination processing is not performed; and or otherwise, determination is performed in sequence according to data structures of distance stratification. Under the condition of monitoring a large number of aircrafts in the monitoring center, unnecessary border-crossing monitoring and calculation is avoided, so that the executing efficiency of the border-crossing automatic monitoring and calculating for the aircraft is improved.

Description

technical field [0001] The present invention relates to a navigational aircraft cross-border monitoring method based on satellite navigation positioning monitoring in the field of aviation monitoring, especially suitable for using satellite navigation to realize positioning, and under the mode of transmitting the positioning data to the monitoring center through a data communication link, the monitoring center automatically monitors in real time Monitor and judge whether more than 1,000 aircraft have entered the no-fly zone. Background technique [0002] According to the national low-altitude airspace management regulations, low-altitude airspace is divided into controlled airspace, surveillance airspace and reporting airspace. Navigable aircraft cannot fly into the controlled airspace (ie no-fly zone). Due to airflow push and other reasons, when the general aviation aircraft actually flies, it will fly into the controlled airspace (that is, cross the boundary), resulting in...
