Fifth Gait Technologies has assembled the best-qualified team of subject matter experts (SMEs) to develop the MDA Space Radiation Environment (MDA-SRE) module to characterize in-flight radiation environments for MDA missile systems. The MDA-SRE program meets the objective of the MDA13-013 SBIR call for Space Radiation Environments. Our team has the proven experience to develop, integrate, and distribute a computational toolkit (MDA Solar and Cosmic Ray Environment and Effects Model or SCREEM) to fill this need. Our SMEs includes the developers of the CREME-86, CREME-96, and CREME-MC.
