The present invention provides a traffic management system for managing unmanned aerial systems (UASs) operating at low-altitude. The system includes surveillance for locating and tracking UASs in uncontrolled airspace, for example, in airspace below 10,000 feet MSL. The system also includes flight rules for safe operation of UASs in uncontrolled airspace. The system further includes computers for processing said surveillance and for applying the flight rules to UASs. The traffic management system may be portable, persistent, or a hybrid thereof.

Systems and methods that coordinate assignments of aircraft operating within a controlled airspace to ground radios are provided. In one embodiment, such a system includes an air traffic control (ATC) facility (12), a plurality of ground radios (16A-16C), and a network manager (20) communicatively coupled to the air traffic control facility (12) and the ground radios (16A-16C). The air traffic control facility is responsible for controlling aircraft (14A-14I) operating within the airspace (10) and providing ATC information to the network manager (20). The ground radios (16A-16C) are operable to provide communications between the air traffic control facility (12) and the aircraft (14A-14I). The network manager (20) is operable to assign each aircraft (14A-14I) to one of the ground radios (16A-16C) based on network management considerations using the ATC information.

Provided is an airspace controller for creating and managing dynamic airspace for different users. The airspace controller may produce different dynamic airspace for each user by continually updating static controlled airspace maps with user-specific flight information including user-planned flights, authorization status of the user's flights, waivers, controlled airspace restrictions, and real-time flight telemetry. The airspace controller may generate a static airspace map for all users with different airspace user interface (“UI”) elements at different regions that correspond to different airspace restrictions in effect at those regions. The airspace controller may create dynamic airspace for each user by modifying the static airspace map to include flight UE elements over regions of the static airspace map where user-defined flights are to occur. The flight UE element may include shapes that correspond to flight areas defined for a flight plan, and one of several graphical representations to identify authorization status of the flight.

The invention discloses a self-adaptive adjusting method and device for a unit window in a controlled airspace. The self-adaptive adjusting method comprises the following steps: determining the related flight path judgment range when an observation point is detected in the controlled airspace, wherein the related flight path judgment range comprises the unit window with the observation point and other unit windows adjacent to the unit window with the observation point; determining the adjustment scheme of the unit window (narrowing the unit window) if it is judged that no system flight path relevant to the observation point exists in the related flight path judgment range and at least on system flight path exist in the unit window with the observation point; and redividing the controlled airspace according to the determined adjustment scheme of the unit window. Because the unit window can be adjusted in a self adapting way according to the condition of the controlled airspace, the leakage of the correlation can be avoided, the amount of calculation can be reduced, the correlation judgment efficiency can be improved, and more calculation resources of the system can be saved.

A method for operating an, at least temporarily, unmanned aircraft or spacecraft wherein a flight procedure of the aircraft or spacecraft is carried out in controlled airspace using a previously cleared flight plan, wherein a C2 link is at least temporarily unavailable, and wherein at least one sensor device of the aircraft or spacecraft identifies a dangerous and / or emergency situation which makes it necessary to deviate from the cleared flight plan. To have available a method which makes it possible for an at least temporarily unmanned aircraft or spacecraft to react independently to particular dangerous and / or emergency situations and to avoid damaging events, a control device of the aircraft or spacecraft independently uses a wireless data link to a supervisory authority in order to agree to a changed flight plan containing at least one change.
