A method for validating a terrain database includes a step of simulating flights based on trajectory data for an aircraft, the flight simulations being speeded up, a step of determining terrain collision risks by means of a system for signalling terrain collision risks based on the speeded-up flight simulations, a step of determining the origins of terrain collision risks with a view to validating or not validating the terrain database.

This invention involves a modular LIDAR altimeter for aircraft to aid in navigation. Principally, this invention gathers altimetric readings that are more highly accurate than traditional data typically available to the average pilot. The modular LIDAR altimeter is designed to be easily attached to and detached from the outside of the aircraft, resulting in no modifications to the aircraft itself. The invention uses a LIDAR to perform ranging measurements enclosed in a container consisting of all the components necessary for its operation. Data from the modular LIDAR altimeter is wirelessly transmitted to be interpreted by a separate device.

An example autonomous or remotely piloted aircraft includes a virtual aperture radar system including a plurality of antennas relationally positioned on one or more surfaces of the aircraft such that individual beams from each of the plurality of antennas scan respective volumes around the aircraft and the respective volumes together substantially form an ellipsoidal field of regard around the aircraft, and a computing device having one or more processors configured to execute instructions stored in memory for performing functions of: combining the respective volumes together to form an image representative of the ellipsoidal field of regard around the aircraft, and identifying one or more objects within the image.

A method for automatically proposing an air conflict resolution, the method includes a step of receiving air conflict and air situation data at a time when an air conflict is detected, the method comprising the steps of: determining a conflict category associated with the detected air conflict based on the conflict data; determining a degree of relevance in proposing a resolution to the air conflict according to the category and the air situation; determining one or more types of resolution to be applied to resolve the detected air conflict according to the degree of relevance; determining set of alternative trajectories corresponding to the one or more types of resolution; determining a set of candidate trajectories from among the set of alternative trajectories, a candidate trajectory being an alternative trajectory which does not generate an air conflict; selecting, from among the candidate trajectories, a candidate trajectory which fulfills a selection criterion relating to the operational relevance of the candidate trajectories and to the acceptability of the candidate trajectories by the flight plan management system; returning the candidate trajectory, the candidate trajectory being saved and re-evaluated as long as it does not generate an air conflict or has not been accepted by an air traffic controller.

The present disclosure relates to a collision avoidance concept comprising emitting a modulated light beacon from an object, wherein a luminance of the light beacon is modulated based on a useful signal carrying information on a position of the object, detecting, by an event-based vision sensor of a vehicle, the modulated light beacon of the object and outputting an event signal in response to a detected change in luminance of the modulated light beacon, and estimating a distance between the object and the vehicle based on the event signal.

In various aspects, a first set of attributes associated with a target location are determined. The target location is a location that one or more items are to be delivered to by an unmanned aerial vehicle (UAV). The first set of attributes are compared with a second set of attributes. The second set of attributes indicate attributes of each UAV of a plurality of UAVs. Based on the comparing, a UAV, of the plurality of UAVs, is recommended to deliver the one or more items to the target location.
