Persistent observation, a persistent problem For all the improvements in spatial and spectral resolution, agility and accuracy, satellites suffer from one serious drawback: they have to follow the laws of orbital mechanics and keep moving around the Earth. This means they cannot hang around an interesting location, to keep a persistent watch on it, except… Continue reading High-altitude Pseudosatellites, the future of Earth observation?
