There is a growing need in the space industry for large antenna apertures that can be deployed from existing launch vehicle payload fairings in order to increase ground to space communications sensitivity. The solutions presented here involves a sparse antenna array made from self-deploying, folded box trusses which use locking joints and tension cables to create a parabolic reflector. This paper presents method for simulating a largely unconstrained deployment of a single box truss. Results of this simulation establish the framework for future work that will include an entire truss system of eight truss boxes that constitute an entire arm of the sparse antenna array.
