In this work we study closed inflationary universe models by using a tachyonic field theory. We determine and characterize the existence of an inflationary universe with Ω > 1. We found that these models are less restrictive compared to the standard ones with a scalar field. We use recent astronomical observations to constraint the parameters appearing in the model.
