Oriented object detection is a challenging task in aerial images since the objects are displayed arbitrary directions and frequently densely packed. The mainstream detectors describe rotating using five-parameter or eight-parameter representations, which have representation ambiguity for orientated definition border loss discontinuity regression process. We proposed an innovative method based o...

Abstract Long-term maintenance missions present a challenge for low-orbit heterogeneous area-to-mass ratio (AMR) microsatellite constellations due to inconsistent fuel consumption and carrying capacity. Based on the idea of cooperative control, fuel-rich satellites is properly increased in this paper assist fuel-starved saving fuel, so as optimize balance each satellite extend controllable life...
