ISO 14954:2005 normalizes the exchange of mathematical models between spacecraft contractors (SCC) and launch service providers (LSP). It identifies standard methods for modelling the dynamic behaviour of both launch vehicles (LV) and spacecraft (SC) particularly when they are coupled prior to launch and during the early moments of the launch phase.
In standard mode, the delivered models represent dynamic and static behaviour at the launcher interface. The requirements provided in ISO 14954:2005 are the minimum necessary for dynamic coupled analysis. They may be not sufficient for stress analysis.
ISO 14954:2005 does not include the validation of spacecraft models.
