This paper addresses the problem of navigating an Unmanned Aerial Vehicle in an environment where GPS quality is degraded or lost. A method is described to return the aircraft from the GPS-degraded region to its launch point by means of visual navigation techniques. We record a string of overlapping images, or keyframes, on the outbound flight. On the return journey, a control law based on the homography...
In this paper a fast horizon detection algorithm is introduced, which is run on an airborne visual system. It is important to run the horizon detection as fast as possible, and also with low power consumption. Hence we developed an algorithm, which has low complexity. The horizon detection uses attitude information provided by the flight control computer of the aircraft and it corrects the horizon...
Payload sensory information is critical to improve the degree of realism and context awareness in multi-UAV simulators. This paper describes a simulator for multi-payload cooperative UAS missions. It adopts an open Software-In-The-Loop (SITL) approach where the simulation of payload sensors and UAV navigation systems are distributed providing high degree of realism. The proposed simulation tool imposes...
