![]() This Strategic Air Command document shows where the U-2 carried the cameras, three SIGINT sensors, and nuclear test sampling equipment. The NSA no longer considers TELINT a subtype of ELINT ( source). the continuous stream of data regarding location, speed, and other instrument readings to controllers on the ground. TELINT, Telemetry Intelligence, deals with device telemetry, i.e.OpELINT’s mission is to assist military operations through the generation of threat assessments (known as tactical ELINT), finding ELINT targets, and defining their “operational pattern” ( source). OpELINT is the NSA’s abbreviation of Operational ELINT, often called Electronic Order of Battle.Countermeasures can then develop using this intelligence as a guide. TechELINT can illuminate the general capabilities of a system, for example, a radar. TechELINT, or Technical ELINT, provides technical information on the signal and device emitting said signal ( source).This has the effect of narrowing down the geographical search for a target ( source).ĮLINT, or Electronic intelligence, refers to intelligence derived from electronic signals. Signalling channel interception deals with the metadata that allows communication links with a desired target.Text interception, including emails, SMS, morse code, and fax. ![]() phone calls, unencrypted radio communications, and bugs. 1.1 COMINTĬOMINT, or Communications intelligence, collects and analyses intercepts the communication signals of groups or individuals ( source). The first two have additional subcategories. Types of SIGINT include COMINT, ELINT, and FISINT. As this definition implies, SIGINT is a broad discipline. Practitioners usually do this through intercepts, the “listening-in” of transmissions not intended for the interceptor. SIGINT, or signals intelligence, refers to intelligence derived from electronic signals. SIGINT will remain a vital component in intelligence operations for as long as signals are a part of communicating. The prevalence of smart devices is a great example, with all transmitting and exchanging data via the Internet of Things ( source). Zane Craig)Īs technology improves, so too will our reliance on signals. Pennsylvania National Guard Soldiers train March 17, 2022, at Fort Indiantown Gap, Pa., on the new Tactical Dismounted Electronic Warfare and Signals Intelligence (TDEWS) system. These include radar, weapons systems, diplomatic communications, electronically monitored infrastructure, finance, industry, and more. Signals can come from many systems, and SIGINT is interested in them all. ![]() This branch of intelligence is called signals intelligence, or SIGINT. Simultaneously, intelligence experts recognised the vulnerabilities present in transmitting information through signals that do not abide by national borders. Militaries and governments immediately understood the massive benefit provided by beyond-line-of-sight and later international communications.Īrmies could better organise in the field, while governments could conduct diplomacy more centrally and rapidly. ![]() Electricity revolutionised the means by which communication happens. These include instruments (such as drums), smoke signals, and flags. Well before recorded history, various means of relaying information using nonelectrical systems emerged. Technology forms the backbone of the way the world communicates.
