In this paper, a method to calculate alerting thresholds is outlined along with the assumptions and an example. First, the definitions and recommendations of the FAA sponsored Sense-and-Avoid (SAA) workshop report has been adapted to a formal mathematical definition. These definitions are then realized using assumptions and other logic and are translated into a more concrete SAA scenarios. Alerting...
Collision avoidance systems, whether for manned or unmanned aircraft, must reliably prevent collision while minimizing alerts. Deciding what action to execute at a particular instant may be framed as a multiple-objective optimization problem has explored methods of efficiently computing the that can be solved offline by computers. Prior work optimal collision avoidance logic from a probabilistic model...
The utilization of unmanned aerial vehicles requires the ability to navigate in urban or unknown terrain where many moving and/or stationary obstacles of different types and sizes may endanger the safety of the mission. Large efforts have been addressed to resolve conflicts to unmanned aircraft. This paper explores the fundamental concept and presents an up-to-date survey of the collision sensing,...
