ATI's Glossary Of Unmanned Aircraft Vehicles Definitions & Terms

Share |

ATI has several courses on Unmanned Aircraft Systems (UAS) including

The following acronyms and definitions are useful for understanding Unmanned Aircraft Systems including UAS Definitions, Concepts & General UAS Principles.

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot on board. Its flight is controlled either autonomously by computers in the vehicle, or under the remote control of a pilot on the ground or in another vehicle. There are a wide variety of drone shapes, sizes, configurations, and characteristics. Historically, UAVs were simple remotely piloted aircraft, but autonomous control is increasingly being employed.

They are deployed predominantly for military applications, but also used in a small but growing number of civil applications, such as policing, firefighting, and nonmilitary security work, such as surveillance of pipelines. UAVs are often preferred for missions that are too "dull, dirty, or dangerous" for manned aircraft. the United States, the United States Navy and shortly after the Federal Aviation Administration have adopted the name unmanned aircraft (UA) to describe aircraft systems without a flight crew on board. More common names include UAV, drone,remotely piloted vehicle (RPV), remotely piloted aircraft (RPA), remotely operated aircraft (ROA). These "limited-size" (as defined by the FAI) unmanned aircraft flown in the USA's National Airspace System, flown solely for recreation and sport purposes such as models, are generally flown under the voluntary safety standards of the Academy of Model Aeronautics, the United States' national aeromodeling organization. To operate a UA for non-recreational purposes in the United States, users must obtain a Certificate of Authorization (COA) to operate in national airspace.[20] At the moment, COAs require a public entity as a sponsor. For example, when BP needed to observe oil spills, they operated the Aeryon Scout UAVs under a COA granted to the University of Alaska Fairbanks.[21] COAs have been granted for both land and shipborne operations.

The term unmanned aircraft system (UAS) emphasizes the importance of other elements beyond an aircraft itself. A typical UAS consists of the:

  • unmanned aircraft (UA)
  • control system, such as Ground Control Station (GCS)
  • control link, a specialized datalink
  • other related support equipment.

For example, the RQ-7 Shadow UAS consists of four UAs, two GCSs, one portable GCS, one Launcher, two Ground Data Terminals (GDTs), one portable GDT, and one Remote Video Terminal. Certain military units are also fielded with a maintenance support vehicle.

Because of this systemic approach, unmanned aircraft systems have not been included in the United States Munitions List Category VIII – Aircraft and Associated Equipment. Vice versa, the “Unmanned Aerial Vehicle Systems” are clearly mentioned at paragraph 121-16 Missile Technology Control Regime Annex of the United States Munitions List. More precisely, the Missile Technology Control Regime Annex levels rocket and unmanned aerial vehicle systems together.

The term UAS was since adopted by the United States Department of Defense (DOD) and the British Civil Aviation Authority (CAA).

The term used previously for unmanned aircraft system was unmanned-aircraft vehicle system (UAVS).

The development and implementation of concepts, doctrines, procedures and designs to achieve and maintain the required levels of compatibility, interchangeability or commonality in the operational, procedural, material, technical and administrative fields to attain interoperability.

Storage

a) The retention of data in any form, usually for the purpose of orderly retrieval and documentation. b) A device consisting of electronic, electrostatic or electrical hardware or other elements into which data may be entered, and from which data may be obtained.  

Surveillance

The systematic observation of aerospace, surface or subsurface areas, places, persons, or things, by visual, aural, electronic, photographic, or other means.  

Synthetic Aperture Radar (SAR)

A system that uses the frequency shifts associated with the motion of the sensor (Doppler shift) to produce an image with higher resolution then would be available with only the radar system’s beam width and pulse length. It requires complex data processing after collection of the radar data. Complements photographic and other optical imaging capabilities because of the minimum constraints on time-of-day and atmospheric conditions and because of the unique responses of terrain and cultural targets to radar frequencies.  

System Architecture

Defines the physical connection, location and identification of the key nodes, circuits, networks, war fighting platforms, etc., associated with information exchange and specifies systems performance parameters. Constructed to satisfy operational architecture requirements per the standards defined in the technical architecture.  

Target

a) A geographical area, complex, or installation planned for capture or destruction by military forces. b) In intelligence usage, a country, area, installation, agency, or person against which intelligence operations are directed.  

Target Acquisition

The detection, identification, and location of a target in sufficient detail to permit the effective employment of weapons. Increasingly applied to reconnaissance as the object(s) of search and location activity, whether to provide intelligence data or to cue weapon systems directly.  

Targeting

The ability to report the position (may include speed and direction) of a target detected with an AV payload. Target position is reported in terms of latitude and longitude (may include altitude) or in terms relative to a point. Target position information is sufficiently accurate to support weapon system fire control requirements.  

Technical Architecture

A minimal set of rules governing the arrangement, interaction, and interdependence of the parts or elements whose purpose is to ensure that a conformant system satisfies a specific set of requirements. It identifies system services, interfaces, standards, and their relationships. It provides the framework, upon which engineering specifications can be derived, guiding the implementation of systems. Simply put, it is the “building codes and zoning laws” defining interface and interoperability standards, information technology, security, etc.

Tracking

Accurate location and updating of target positions (in terms of geographic co-ordinates) by radar, optical or other means.  

Uninhabited Aerial Vehicle /Unmanned Aerial Vehicle (UAV)

A powered, aerial vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload.  

UAV system

Includes the air vehicles, modular mission payloads, data links, launch and recovery equipment, mission planning and control stations, data exploitation stations and logistic support.  

UAV Control System (UCS)

The functional set charged with control of the AV and interfacing with C4I, the UAV payload and UAV System operator(s). Includes all the UAV control systems and encompasses launch and recovery system.  

United States Message Text Format (USMTF)

Fixed format, character-oriented messages which are manreadable and machine processable.  

Variable Message Format (VMF)

Used between systems requiring variable bit-oriented messages.  

Vehicle Specific Information

Information sent to or from the air vehicle that is not contained in the core, generic DLI message set.  

Vehicle Specific Module (VSM)

A function that resides between the DLI and the air vehicle subsystem. Facilitates compliance with this STANAG by acting as a bridge between standard DLI data formats, and protocols, and a specific air vehicle.  

Video Imagery

A sequence of images, with metadata, which is collected as a timed sequence of images in standard motion imagery format, managed as a discrete object in standard motion imagery format, and displayed as a sequence of images. Video imagery is a subset of the class of motion imagery.  

Warnings

An alert indicating a hazardous condition requiring immediate action to prevent loss of life, equipment damage, or failure of the mission.  

Waypoint

A point on a UAV route which is defined by latitude/longitude. Altitude is usually defined.  

Waypoint Control

Semi-autonomous or man-in-the-loop method of air vehicle control involving the use of defined points (latitude/longitude/altitude) to cause the UAV (air vehicle, sensor(s), weapons, dispensable payloads, onboard systems, etc.) to accomplish certain actions.
