Satellite surveillance is a technique used by intelligence agencies to gather information about activities on the ground by using satellites orbiting the Earth. Satellites can provide a wide range of data, including images, videos, and signals intelligence, which can be used to monitor the movements and activities of individuals and groups, track the location of vehicles and ships, and identify potential security threats.
There are several different types of satellites used for surveillance purposes, including optical satellites, which can capture high-resolution images of the ground, and radar satellites, which can penetrate clouds and provide images of the ground surface even at night. Additionally, satellites equipped with signals intelligence capabilities can intercept and analyze communications between individuals and groups, providing valuable intelligence on potential threats.
Satellite surveillance is a powerful tool in the arsenal of intelligence agencies, as it allows them to monitor activities in remote or inaccessible locations, track the movements of individuals and groups over time, and identify potential security threats before they become major issues.
