Satellite surveillance technology
Satellite surveillance technology refers to the use of commercially owned and operated Earth-orbiting satellites that capture high-resolution images of the Earth's surface. This technology allows law enforcement and intelligence agencies to conduct surveillance without being detected by their targets, significantly reducing the risks associated with traditional surveillance methods. Initially developed for military use, satellite surveillance has evolved to become a vital tool for various applications, including monitoring land usage and gathering intelligence on criminal activities.
Modern commercial satellites can capture images with resolutions of one meter or less, enabling detailed observation of objects and patterns on the ground. This capability has proven valuable for law enforcement, aiding in operations such as monitoring drug trafficking and planning tactical responses. Unlike aircraft, satellites provide continuous coverage and stealth, making them an efficient alternative for expansive territorial surveillance, including national borders.
However, the use of satellite surveillance has sparked debate over privacy rights, with concerns raised about potential violations of the Fourth Amendment in the U.S. Courts have generally upheld the legality of warrantless satellite surveillance. In contemporary contexts, such as the conflict in Ukraine, satellite technology has emerged as a critical asset in military strategy, showcasing both the utility and the challenges associated with modern surveillance capabilities.

DEFINITION: Commercially owned and operated Earth-orbiting satellites capable of producing high-resolution photographs of the ground from space.
SIGNIFICANCE: Most surveillance requires either the person doing the surveillance or the equipment used to be in proximity to the target being watched, so there is risk that the target will become aware of the surveillance. The use of satellite technology, however, enables law-enforcement and other agencies to conduct surveillance that is undetectable by the targets.
Shortly after the first artificial satellites were placed into Earth orbit, plans were made for surveillance satellites. Such spy satellites were used by the military and intelligence agencies of national governments to monitor the activities of other nations from space. Commercial uses for imaging satellites eventually led to the development of remote-sensing satellites capable of monitoring land usage. With advances in technology, commercial satellites have been created with capabilities far in excess of those held by military satellites of only several years ago. Modern commercial satellites are capable of capturing images with resolutions of one meter (a little more than three feet) or less, meaning that they are capable of distinguishing between objects at least one meter apart.
The proliferation of high-resolution commercial satellites has led to a market for the data they collect. Several agencies in the United States contracted to use DigitalGlobe’s QuickBird satellites to acquire high-resolution images; QuickBird re-entered the atmosphere in January 2015. This type of surveillance can provide police with information such as the approximate numbers of people involved in suspected gang or drug-trafficking activities and their patterns of movement. Satellite-captured images can also provide law-enforcement agencies with information on the locations of fences, walls, trees, vehicles, and other obstacles in particular areas, which can be very useful, for example, when special weapons and tactics (SWAT) teams are preparing for raids. Alternative methods of surveillance, such as by aircraft, could alert suspects to police activity and potentially put officers at risk. Satellite surveillance also enables federal authorities to monitor national borders in remote regions that are difficult to monitor in other ways.
Commercial satellite technology began as remote sensing to monitor land usage, and law-enforcement agencies still use satellites for this purpose: to look for cultivated fields of or other controlled substances. Such surveillance can also be done by aircraft, but a single satellite can cover more area in more locations than a small fleet of aircraft. Also, satellites offer complete stealth surveillance, whereas aircraft can often be heard or spotted by persons on the ground. In addition, unlike aircraft, which must be fueled and flown on specific missions, satellites are always on duty. All that authorities need is to access the images.
Some privacy advocates have challenged law-enforcement agencies’ uses of satellite surveillance as violations of the right to protection from unlawful searches guaranteed in the Fourth Amendment to the US Constitution. Most law-enforcement agencies argue that surveillance through satellite images does not require warrants. So far, the courts have permitted warrantless satellite surveillance.
In modern times, satellite surveillance technology has been an important tool in warfare. After Russia invaded Ukraine in 2022, Ukraine relied on information from satellites to target invading forces. The war zone became a testing ground for emerging surveillance technologies. Russia, meanwhile employed an array of tactics in its attempts to jam or hack satellite networks used by Ukraine's armed forces.
