Foreign instrumentation signals intelligence
Encyclopedia
In telecommunication
, the term foreign instrumentation signals intelligence (FISINT) has the following meanings:
1. Intelligence information
derived from electromagnetic emissions associated with the testing and operational deployment of foreign aerospace, surface, and subsurface systems.
2. Technical information and intelligence information derived from the intercept
of foreign instrumentation signals by other than the intended recipients. Foreign instrumentation signals intelligence is a category of signals intelligence.
Foreign instrumentation signals include but are not limited to signals from telemetry
, beaconry, electronic interrogators, tracking/fusing/arming/firing command
systems, and video

Telecommunication
Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded...
, the term foreign instrumentation signals intelligence (FISINT) has the following meanings:
1. Intelligence information
Information
Information in its most restricted technical sense is a message or collection of messages that consists of an ordered sequence of symbols, or it is the meaning that can be interpreted from such a message or collection of messages. Information can be recorded or transmitted. It can be recorded as...

2. Technical information and intelligence information derived from the intercept
Intercept
Intercept may refer to:*X-intercept, the point where a line crosses the x-axis*Y-intercept, the point where a line crosses the y-axis*Interception *The Mona Intercept, a 1980 thriller novel by Donald Hamilton...

Telemetry
Telemetry is a technology that allows measurements to be made at a distance, usually via radio wave transmission and reception of the information. The word is derived from Greek roots: tele = remote, and metron = measure...

Command (computing)
In computing, a command is a directive to a computer program acting as an interpreter of some kind, in order to perform a specific task. Most commonly a command is a directive to some kind of command line interface, such as a shell....

data
Data
The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which...
