Ground-based Sense and Avoid Support for Unmanned Aircraft Systems
The ability to fly an unmanned aircraft regularly and routinely for commercial or civilian applications, in non-segregated, airspace requires a sense and avoid capability. The Mobile aircraft Tracking System (MATS) is a Ground-Based Sense And Avoid (GBSAA) system. The MATS consists of a primary radar, an ADS-B receiver and a transponder interrogator. The Smart Skies project provided an opportun...
متن کاملConflict Detection Metrics for Aircraft Sense and Avoid Systems ?
The task of an airborne collision avoidance system is to continuously evaluate the risk of collision and in the case of too high risk initiate an evasive action. The traditional way to assess risk is to focus on a critical point of time. A recently proposed alternative is to evaluate the cumulated risk over time. It is the purpose of this contribution to evaluate the difference between these tw...
متن کاملUnmanned aircraft systems as wingmen
This paper introduces a method to integrate Unmanned Aircraft Systems (UASs) into a highly functional manned/ unmanned team through the design and implementation of 3D distributed formation/flight control algorithms with the goal to act as wingmen for a manned aircraft. The proposed algorithms are designed to increase UAS autonomy, dynamically modify formations, utilize standard operating forma...
متن کاملChoosing Replanning Strategies for Unmanned Aircraft Systems
Unmanned aircraft systems use a variety of techniques to plan collision-free flight paths given a map of obstacles and nofly zones. However, maps are not perfect and obstacles may change over time or be detected during flight, which may invalidate paths that the aircraft is already following. Thus, dynamic in-flight replanning is required. Numerous strategies can be used for replanning, where t...
متن کاملSense and Avoid for Unmanned Aircraft Systems: Ensuring Integrity and Continuity for Three Dimensional Intruder Trajectories
This research aims at developing methods to meet safety targets for sense and avoid (SAA) sensors of Unmanned Aircraft Systems (UAS) through integrity and continuity risk evaluation. The SAA problem is presented as a three-dimensional, two-body problem. A Kalman filter approach is introduced to accommodate arbitrary sensor suites. Aircraft relative position and velocity estimates, referred to a...
