One of the components of the approved extension to the accelerator facility at GSI/Darmstadt is a storage ring for high luminosity phase space cooled antiprotons with momenta between 1.0 and 15 GeV/c. Antiproton annihilation reactions on protons and nuclei will be investigated with a detector system called PANDA. One of the crucial items of the central tracking system is the Straw Tube Tracker (STT). The STT will consist of the 11 double layers, 5 of them are skewed. The straws will have a diameter 8 and 10 mm. The STT needs high position resolution (∼ 150µ m) and high rate capabilities, to handle the high events rate (10⁷ events/s). This poster will present an overview of the simulations and prototyping performed to investigate performance of the STT for PANDA.
