A real-time aircraft bird congestion indicator system for measuring congestion in an airspace between aircraft and birds uses one or more radars to continuously survey an airspace around an airport or aerodrome and continuously generate aircraft tracks and bird tracks in the airspace. A congestion processor connected to the radar(s) receives the aircraft and bird tracks and processes them to periodically generate a congestion indicator that measures the congestion in the airspace. A display processor connected to the congestion processor receives the congestion indicator which is updated periodically by the congestion processor and displays the congestion indicator to a user, generates an alert if the congestion indicator falls outside set operating limits, and/or sends the congestion indicator or alert to another system.

The present disclosure provides a method, a device and a system for guiding an unmanned aerial vehicle to land. A navigation equipment on the unmanned aerial vehicle sends a landing instruction to the ground, so that a landing platform receiving the landing instruction displays a landing pattern. The navigation equipment scans image of the ground to identify the landing pattern, and guides the unmanned aerial vehicle to land at the landing pattern and land on the landing platform eventually. The landing platform displays a landing pattern according to the received instruction, and the unmanned aerial vehicle lands at the landing pattern, so that the unmanned aerial vehicle lands quickly and conveniently without extensive calculation.
