A satellite constellation is a network of satellites. They aren’t geostationary, but can cover the whole globe because there’s so many of them. When a connection to one drops, it hands off to the next one. GPS and Starlink are examples.
Radar satellites use radar to image the earth, so called SAR. It can be used to observe the ground even with cloud cover.
