Abstract
The Defence Research Establishment Valcartier currently supports the development of a generic six-degree-of-freedom simulation model of a tactical air-to-air missile. For efficiency, the development of this missile simulation takes advantage of already existing model components when available, one example being the modeling of the missile dynamics. The documented six-degree-of-freedom missile dynamics model currently available uses a non-standard system of axes, where the x axis is forward, the z axis is lateral and the y axis is downward, to describe the missile body, seeker and missile-target line-fo-sight vector. However, the most common axes system in current simulation models and in the DREV library of weapon system model components is the NED system (North-East-Down), which uses a forward x axis, a downward z axis and a lateral y axis. In order to maintain compatibility with the existing library of components, this missile dynamics model has been modified to use the NED standard system. The mathematical relations of the resulting model are presented.
