TRAJECTORY-BASED SENSE-AND-AVOID SYSTEM

摘要

A trajectory-based sense-and-avoid system (168) for use on an aircraft (100) is provided that utilizes 4-D constructs (166, 192), such as 4-D trajectories or 4-D polytopes, to maintain separation from other aircraft (118) and/or to avoid collisions with other aircraft (118). In certain embodiments the trajectory-based sense-and-avoid system (168) utilizes 4-D trajectories provided from an external source and/or 4-D trajectories estimated based on a variety of data sources during operation.
