SBIR-STTR Award

The goal of the proposed work is to provide the Air Force with a state-of-the-art model of the outer zone energetic charged particles, including data assimilation capabilities. The UCLA-developed Versatile Electron Radiation Belt (VERB) model will be optimized for various measurements obtained on various satellite orbits by different instruments. We will transfer VERB code to SSI, test and validate it. We will perform data assimilation using LEO, MEO, and GEO satellites, develop documentation, and adapt the codes to Air Force needs and requirements.

Near-Earth space environment is hazardous to satellites. This harsh particle radiation can penetrate protective shielding, accumulate in sensitive materials and can damage even well shielded electronic components causing temporary malfunctions or a complete system/mission loss. The goal of the proposed work is to provide the Air Force with a state-of-the-art model of the outer zone energetic elections that will include data assimilation capabilities. Data assimilation allows us to utilize a vast array of data, including information at various radial distances and from various satellites to reconstruct the global state of the outer radiation belt. Satellites on different orbits, with different detectors that vary in the range of energies and accuracy, can be naturally included in the analysis of the global state of the system.The work plan of PHASE II is based on the achievements and demonstrated capabilities of PHASE I and detailed discussions with AFRL staff on AFRL needs and requirements. While this product will provide great immediate and mid to long term benefits to the Air Force for its operational fleet of satellites, there is a strong potential commercial market as well.
