摘要

During the Mars 2001 Odyssey aerobraking mission, NASA Langley Research Center performed six-degree-of-freedom simulations to model rotational motion of the spacecraft. The main objective of this study was to assess the reaction-control-system models and their effects on the atmospheric flight of Odyssey. Based on these models, a comparison was made between data derived from flight measurements to simulated rotational motion of the spacecraft during aerobraking at Mars. The differences between the simulation and flight-derived Odyssey data were then used to adjust the model aerodynamic parameters as a result of reaction-control-system firings to achieve a better correlation.
