Mid-Air Collision Avoidance Principles
Unmanned Aircraft Systems are about to replace human pilots not only in dangerous, dull or tedious missions but generally where the human being is the limiting factor including size and economic issues. There is a wide range of applications for which UAVs have to be operated in non-segregated airspace in general and uncontrolled airspace in particular, regardless of civil, governmental or milit...
متن کاملProbabilistic Near Mid-Air Collision Avoidance
We propose a probabilistic method to compute the near mid-air collision risk as a function of predicted ight trajectory. The computations use state estimate and covariance from a target tracking lter based on angle-only sensors such as digital video cameras. The majority of existing work is focused on risk estimation at a certain time instant. Here we derive an expression for the integrated ris...
متن کاملStrategies for Pre-Emptive Mid-Air Collision Avoidance in Budgerigars
We have investigated how birds avoid mid-air collisions during head-on encounters. Trajectories of birds flying towards each other in a tunnel were recorded using high speed video cameras. Analysis and modelling of the data suggest two simple strategies for collision avoidance: (a) each bird veers to its right and (b) each bird changes its altitude relative to the other bird according to a pres...
متن کاملA Reinforcement Learning Based Uavs Air Collision Avoidance
In this paper, we propose to deal with the UAV airspace conflict resolution problem. We propose to search near optimal conflict free policies in virtue of the model-based reinforcement learning. We first analyze the UAV airspace conflict problem and the basic conditions in ensuring collision-free planning, and then discuss the features that effect the optimal action. We then propose the reinfor...
متن کاملModel predictive control approach to global air collision avoidance
Purpose – Most of the existing approaches for flight collision avoidance are concerned with local traffic alone for which the separation is based on the pairwise analysis of aircraft trajectory trends, which is not efficient with regard to some flight path requirements along waypoints. The purpose of this paper is to deal with the global collision avoidance problem which aims at separating airc...
