Abstract: A deployment system comprises a plurality of parallel linear guide rails, securely supported at their respective bases to a deployment portion of the spacecraft. Each of these linear guide rails contains a drive chain which is powered by a motor(s)/output gear box during the deployment sequence. The guide rail chain mechanisms are coupled to each other by means of drive shafts. Therefore, the drive shafts serve a dual purpose: 1) distribute power between the guide rail chain mechanisms as needed and 2) synchronize the guide rail mechanisms. A payload is provided having attach fittings located thereon for engagement with the linear guide rails. These fittings engage the drive chain. In this manner, the motion of the chain drives the payload fittings along the linear guide rails. During deployment, motion of the chains is produced by the motor(s), which accelerate the payload along the length of the guide rails.
