Analysis and Simulation of the Mariner Mars 1971 Scan Platform: Spacecraft Dynamic Interaction

摘要

The Mariner spacecraft as well as most other spacecraft have instrument platforms, antennas, etc., which must move relative to the attitude controlled spacecraft bus structure. As the appendages are moved, reaction forces and torques are produced that disturb the spacecraft attitude. This report develops the equations of motion which describe the dynamic interaction between the spacecraft bus and the movable appendages about a single axis, evaluates the effect of the dynamic interaction on the attitude control subsystem with computer simulations, and makes design recommendations to reduce the impact of this interaction on future attitude control subsystems.
