Imagery satellites fly at a low altitude and effectively cannot "hover" over a site in the same way a drone can. That said, one can correlate the passes of imagery satellites (optical, radar) with other spaceborne RF sensors, and sensors on airplanes & drones (optical, radar, RF etc.), and data from implanted sensors on the ground, to construct a real-time view of the battlespace. The Full Monty of these capabilities, especially data fusion from disparate platforms, would never be released to the world. Fun fact: US overhead systems (NRO satellites) are sometimes quietly used to aid search & rescue activities. A friend of mine, a USAF E-9 who had been read into many compartments during his career, used to do this with the Coast Guard after he retired from the Air Force. Pretty cool stuff. |

Like you mentioned, they do use their capabilities for some things other than just GEOINT:
>In addition to using GEOINT for U.S. military and intelligence efforts, NGA provides assistance during natural and man-made disasters, aids in security planning for major events such as the Olympic Games,[9] disseminates maritime safety information,[10] and gathers data on climate change.[11]
