This paper presents the dynamic and digital simulation of the deployment of rigid solar panels on INTELSAT-V and INS AT spacecraft. Each spacecraft is characterized by very distinct mechanisms for its solar array deployment. The arrays on INTELSAT-V are in a topological tree configuration, while the INSAT arrays are in a closed-loop configuration because of the four-bar linkage deployment mechanism. It is shown that the kinematic control rod on the INSAT has a synchronizing function very similar to that of the closed cable loop on the INTELSAT-V spacecraft. Practical aspects of the modeling and simulation of complex deployment mechanisms are emphasized. The use and limitations of the DISCOS multibody code for deployment dynamics simulations are discussed, and the need for developing specialized simulation tools emphasized.
