Paper Abstract

A central aspect in the design of the Mars lasercom terminal was limiting the line-of-sight jitter of the optical payload due to translational and angular dynamic excitation from the host spacecraft. Line-of-sight jitter analyses were performed on the Mars terminal payload that accounted for the passive and active stabilization systems, the elastic response of the payload, and the detailed elastic characteristics of the isolator. The line-of- jitter was significantly impacted by the coupling between the local dynamic response of the isolator main spring and the payload structure. Critical modes of the payload are identified and the impact of the isolator main spring surge mode is discussed along with mitigation strategies using models correlated to vibration test data.
