The local time of the ascending node of the three Swarm satellites has passed through more than two-and-a half 24-hour cycles, and Swarm Bravo is now separated from Swarm Alpha and Charlie by about 3 h of local time. The nominal 1 Hz data were sub-sampled at 60-s intervals unless ...
Recent NASA satellites data(2000—2017) have shown that human activities in China and India dominate this greening of the planet, thanks to ambitious tree-planting programmes in China and intensive agriculture(集约农业) in both countries. The researchers from Boston University found that global green...
It measured temporal variations of the Earth’s gravity field by tracking through a K-band ranging (KBR) system, the inter-satellite range and range rate between two coplanar, low altitude satellites (GRACE A and B)75. The GRACE Science Data System uses measured inter-satellite range and ...
15) Aliens capable of travelling interstellar distances are reliant on our satellites (they can't use their own or use a couple of ships as relay points?) 16) Aliens capable of travelling interstellar distances apparently are ignorant of a unique invention called a watch and have way of ...
In [42], the feedback error learning of magnetic satellites was controlled using a T2FWNN with elliptic MFs. The learning is based on the feedback error learning method, and the stability of the learning is proven, but also the stability of the overall system, to ensure robustness. The sim...
