Interplanetary Magnetic Field (Copyright © 2011 Exploration Physics International, Inc.)

Space weather, including the solar wind, produces physical phenomena, such as geomagnetic storms and ionospheric disturbances, that affect satellites in earth orbit and terrestrial communications systems. The U. S. Air Force Weather Agency (AFWA) uses computer models to predict space weather...

MSFC Engineering process diagram

The project has four main tasks:

(1) Understand how modeling and simulation is used in systems engineering in general, and in particular, at MSFC. We are interviewing key systems engineering practitioners and managers at MSFC, examining NASA systems engineering standards, and reviewing...

Validation process flowchart

Increasingly, decisions are being made based partially or entirely on models. These decisions may be quite important, with the potential of serious or unacceptable consequences if an incorrect decision is made. The models used to support the decisions may have been newly developed or modified...

Metric of Evil image

Beginning with an initial concept and model provided by the U. S. Army System Simulation and Development Directorate (SSDD), the University of Alabama in Huntsville (UAH) has developed and tested a “Metric of Evil,” a quantitative model of the harm associated with military courses of action...

BRAC modeling image

Due to Base Realignment and Closure (BRAC) actions, approximately 4,500 government positions and 15,000 contractor positions, concentrated in technical, logistical, and acquisition fields, will be moving to Huntsville Alabama over a five year period. Because of retirements, transfers, and job...

Aggregate combat modeling image

Unit-level combat models provide computational efficiency, with the result that they can simulate large scenarios in terms of geographic scope and size of military forces involved and are often able to execute much faster than real-time. However, existing unit-level combat models (such as...

Systems Integration Testing Architecture

The various primary systems of military aircraft and missiles (avionics, propulsion, sensors, and weapons) and the subsystems within them must exchange data in order to perform their functions. Integration testing for those systems and subsystems can be time-consuming, expensive, and difficult,...
