Drones cannot do long term monitoring.
- erikcw 14y agoMy understanding is that drones are preferred for long term/constant monitoring. Spy satellites are not placed in geostationary orbit, so they only have a few minutes of exposure per day to a place of interest as they fly over. The Global Hawk [1] drone is optimized for high altitude loitering. Operating multiple drones in the area is one way to overcome the problem of running out of fuel.
