Abstract

A multi-axis passive isolation system was designed for dual mode operation to minimize pointing error due to spacecraft dynamic disturbances and to minimize payload response due to launch loads for the Mars terminal as part of the Mars Laser Communications Demonstration Project. Numerical optimization techniques using MSC/Nastran finite element software were utilized to explore isolator design configurations using a lower bound frequency constraint of 20 Hz subject to performance and mounting constraints. Response functions were developed that included the frequency spread of the six isolator modes and the rigid-body line-of-sight error due to translational and angular base disturbances that served as merit functions and/or constrained quantities during optimization. The performance of the resulting isolator configurations based on single and six degree-of-freedom isolator models are discussed.
