ARINC 661

The ARINC 661 standard for commercial aircraft cockpit displays normalizes the definition of a Cockpit Display System (CDS) as well as the communication between the CDS and User Applications (UA).

CDS

The Cockpit display systems (or CDS) provides the visible (and audible) portion of the Human Machine Interface (HMI) by which aircrew manage the modern Glass cockpit and thus interface with the aircraft avionics.

CGF

Computer Generated Forces (CGF)—also sometimes referred to as Semi Automated Forces (SAF)—enable you to create high-fidelity simulations to train individuals for the ever-changing realities of the 21st century.

CIGI

Within the visual simulation industry, most image generators have a proprietary interface that is labor intensive to integrate.
As a result, hundreds of thousands of dollars have been spent integrating IG's into various Modeling and Simulation programs. In addition, while most IG's do share common controlling attributes, they do not share a common interface, meaning that there is no mechanism for capitalizing on previous investments.

DIS

Used worldwide by military organizations as well as agencies involved in space exploration and medicine, DIS is a mature open standard for conducting real-time platform level simulations across multiple host computers.

DMSO MIL-Std-2525b

MIL-std-2525b is a US Military standard provides common operational symbology along with details on its display and plotting to ensure the compatibility and interoperability of NATO or US Military Land Component Command, Control, Communications, Computer, Land Intelligence (C4I) systems. NATO APP-6A is its sister standard used by NATO.

GeoTIFF
GIS

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. The acronym GIS is sometimes used for geographic information science (GIScience) to refer to the academic discipline that studies geographic information systems and is a large domain within the broader academic discipline of geoinformatics.

HLA

High Level Architecture (HLA) is a general purpose architecture for distributed computer simulation systems.

The High Level Architecture (HLA) was developed by the U.S. department of defense (DoD) and its primary purpose or function was to integrate and facilitate the interoperability of disparate simulations that were running on a variety of different platforms, and to provide a common framework for their operation together. HLA is intended to have applicability across the complete range of training, analysis, mission control, and engineering functions. It provides an open, standards-based method of implementing distributed simulation environments.

HMI

A human-machine interface (HMI) is typically local to one machine or piece of equipment, and is the interface method between the human and the equipment/machine. An operator interface is the interface method by which multiple equipment that are linked by a host control system is accessed or controlled.

HWIL

Hardware-in-the-Loop – sometimes called HIL or HWIL – is a simulation approach that incorporates hardware interfaces with software.

ISAR

Inverse Synthetic Aperature Radar: A radar technique using Radar imaging to generate a two-dimensional high resolution image of a target.

ISR

ISR, or Intelligence, Surveillance, and Reconnaissance, is the coordinated and integrated acquisition, processing and provision of timely, accurate, relevant, coherent and assured information and intelligence.

MetaFlight

MetaFlight is a high-level description specification for visual databases that dramatically simplifies the ability of the runtime system to use the database with minimal user setup.

While OpenFlight describes and contains the geometry and structure within a single file, MetaFlight describes the structure, organization, file naming, and coordinate systems of all the datasets that comprise a single, more complex database.

OGC CDB

The OGC CDB (Common Database) specification is an open synthetic environment database specification.

As a simulation specification for producing a unified synthetic representation of the world, OGC CDB was developed to respond to and improve upon many aspects of database creation for modeling and simulation.

OpenFlight

OpenFlight is the native file format of Creator and is the de facto standard 3D file format for modeling and simulation.

The logical hierarchical scene description file format in OpenFlight tells the real-time image generator what, when, and how to render, resulting in real-time 3D scenes with unmatched precision and reliability.

SAR

A coherent ground map mode which provides higher azimuth resolution by processing the radar return signal phase to exploit the doppler dependency on azimuth angle.

TerraPage

TerraPage was developed in 1998 to address this key market requirement for an open standard for terrain database paging.

Virtual Texture
In MetaFlight, a virtual texture is the type of dataset used to describe a, usually large, image that is organized into a multi-level system of smaller image tiles.

It is called virtual because the collection of tiles together makes up one single integrated image.
