startup Altitude Angel, located in the U.K, created a new  air traffic management software system, which allows to observe airspace around aircraft and consequently warn about appearance of unpleasant, or unexpected aerial vehicles or changes to airspace.  The system acts in the simple way. After emergence of conflict, the system  makes the necessary routing adjustments, which  allows the drone to separate from other airspace users or fly all over prohibited airspace so the aircraft  can continue  flight without concerns about it’s own security.
