| Summary: | In lunar explorer development program, computer simulator is necessary to provide virtual environments that vehicle
confronts in lunar transfer, orbit, and landing missions, and to analyze dynamic behavior of the spacecraft under these
environments. Objective of simulation differs depending on its application in spacecraft development cycle. Scope of
use cases considered in this paper includes simulation of software based, processor and/or hardware in the loop, and
support of ground-based flight test of developed vehicle. These use cases represent early phase in development cycle
but reusability of modeling results in the next design phase is considered in defining requirements. A simulator architecture
in which simulator platform is located in the middle and modules for modeling, analyzing, and three dimensional
visualizing are connected to that platform is suggested. Baseline concepts and requirements for simulator development
are described. Result of trade study for selecting simulation platform and approaches of defining other simulator components
are summarized. Finally, characters of lunar elevation map data which is necessary for lunar terrain generation
is described. |
