What footprint must ES be in?

Explanation:
In Electronic Support, the goal is to observe and identify signals of interest. For satellite communications, the emissions you’d collect are the downlink transmissions from the satellite to Earth. Therefore you must be in the satellite downlink footprint—the area on the Earth's surface within the satellite’s downlink coverage—so your receivers can actually receive the signal with enough strength. The uplink footprint is the region where ground stations can send signals to the satellite, which isn’t about listening to the satellite’s downlink. The terrestrial downlink footprint and undersea cable footprint aren’t relevant to this satellite-downlink observation context.
