Space Vehicle Conflict Probability for Ellipsoidal Conflict Volumes

Journal of Guidance, Control, and Dynamics, 2007
S PACE vehicles can be protected against collisions with tracked space objects by executing collision avoidance maneuvers [1]. Once a space object is identified as a collision risk, plans can bemade to maneuver the space vehicle to increase the closest approach distance to a safe level.

Conflict Probability Estimations Based on Geometrical and Bayesian Approaches

2007 IEEE Intelligent Transportation Systems Conference, 2007
In this paper, we present two approaches to calculate the probability of conflict between two aircrafts in the airspace. The problem is concerned with a more general problem, that is minimizing the delay caused by airspace congestion. The long-term objective of this work is to reduce the number of potential en-route conflicts through a better ...

Automated Conflict Resolution Utilizing Probability Collectives Optimizer

IEEE Transactions on Systems, Man, and Cybernetics, Part C (Applications and Reviews), 2011
Rising manned air traffic and deployment of unmanned aerial vehicles in complex operations requires integration of innovative and autonomous conflict detection and resolution methods. In this paper, the task of conflict detection and resolution is defined as an optimization problem searching for a heading control for cooperating airplanes using ...

Conflict Probability Estimation for Free Flight

1996
The safety and efficiency of free flight will benefit from automated conflict prediction and resolution advisories. Conflict prediction is based on trajectory prediction and is less certain the farther in advance the prediction, however. An estimate is therefore needed of the probability that a conflict will occur, given a pair of predicted ...

Algorithms for tactical conflict resolution and strategic conflict probability reduction

1st AIAA, Aircraft, Technology Integration, and Operations Forum, 2001
Numerical algorithms are presented for de- termining the dynamic speed and heading maneu- vers required to resolve air traffic conflicts in the horizontal plane. Speed changes are modeled as pe- riods of constant along-track acceleration or decel- eration, and heading changes are modeled as steady turns of constant rate and radius.

A methodology for estimating the probability of potential secondary conflicts

2013 IEEE/AIAA 32nd Digital Avionics Systems Conference (DASC), 2013
In a distributed separation assurance system, each aircraft is equipped with its own conflict detection and resolution capability. An aircraft that is resolving an initial primary conflict has complete state information of all nearby aircraft, so is able to choose a resolution trajectory that is conflict-free from all other aircraft.

Effect of Wind Correlation on Aircraft Conflict Probability

Journal of Guidance, Control, and Dynamics, 2007
A study which examines the effect of wind correlation on aircraft conflict probability estimation is presented. We describe the correlation structure of the difference between the actual wind and the meteorological wind forecasts and discuss how it can be implemented in simulation.

A simplified approach to conflict probability estimation

20th DASC. 20th Digital Avionics Systems Conference (Cat. No.01CH37219), 2002
Describes a relatively straightforward method of estimating the probability of loss of separation between two aircraft at some future time, that is, the probability that they will enter into conflict. Initially the method is developed for encounters in which the planned or predicted speeds of both aircraft are constant during the prediction interval ...

A Geometrical Approach to Conflict Probability Estimation

Air Traffic Control Quarterly, 2002
A method of estimating conflict probability is described. Initially the method is presented considering only along-track errors but subsequently cross-track errors are included. Graphs of conflict probability illustrate limits on the levels of performance that may be attained in medium-term conflict detection and resolution (in the absence of measures ...
