A Modelica Library for Space Flight Dynamics

The Modelica Space Flight Dynamics Library has been developed as a unified environment to be used throughout the design cycle of the Attitude and Orbit Control System (AOCS) for a generic multibody, possibly flexible, spacecraft. The library architecture has been recently redesigned, exploiting at its best Modelica’s reusability, flexibility and modularity features. In this contribution the main benefits of the Space Flight Dynamics Library are discussed with special emphasis posed upon flexibility and advantage of exploiting Modelica’s nonlinear dynamic inversion capability for preliminary assessment of disturbance torques in nominal orbit and attitude.
