Next, employing homogeneous coordinate transformation and the Euler axis optimal path planning method, we establish an imaging model for dynamic star source scanning with continuous compensation of inertial space satellites and payload. This achieves high signal-to-noise ratio imaging of dynamic star ...

This objective is beneficial to lightweight airborne systems such as drones, small satellites, and space-based power (SBP)37 systems, in which the antenna weight comes at the expense of other functionality, or affects the economical viability of the system. The design uses a single 25 μm ...
But for astronauts(宇航员) in space, they need to use special ways to protect themselves from them, said Xinhua. For example, they won't go on spacewalks when there are "sun storms". Also, the particle storms may stop some satellites(卫星) from working, so they may bring trouble to t...
This paper presents a deep learning model based on an active learning strategy. The model achieves accurate identification of vegetation types in the study area by utilizing multispectral data obtained from preprocessing of unmanned aerial vehicle (UAV)
