Abstract: A deployment trajectory design approach of the hoop truss deployable space antenna is proposed. Optimization method is used to select Bezier curves as the input motion trajectory of driving cable, which guarantees the continuity of deployment acceleration and efficiently reduces the peak value. As a result,
the impact on antennas is reduced. Numerical simulations demonstrate that the deployment should be an acceleration\|deceleration process without mid\|uniform\|speed period.

Key words: Deployable antenna, Deployment design
