EO Sensor Analysis SimApp™

Space-Borne EO sensors are highly sensitive instruments that must survive the harsh environments of launch and of space. Product teams design and deliver the hardware, ensuring success the first time around. As failures are costly and often highly visible, a great deal of care and effort goes into the design, analysis and T-VAC testing of these instruments before launch.  Simulation of these complex, multi-physics systems requires teams of Subject Matter Experts (SME’s) using a variety of different COTS simulation tools. Working in today’s hierarchical and ”silo-based” organizations, and using a number of highly-fragmented analysis tools, each iteration takes an unacceptably long time to complete.

Comet Solutions, in close collaboration with engineers in this field, has developed a SimApp™ that has made a significant advance in the ideal of fully integrated STOP analysis. While respecting the unique skills and tools of each discipline (using industry-standard tools such as Thermal Desktop, Nastran, Abaqus, SigFit, and Code V), the Comet EO Sensor Analysis SimApp™ also uniquely enables the ultimate goal of a complete modeling environment that supports and facilitates Model Based Systems Engineering.

Using this integrated simulation environment, engineers at The Aerospace Corp, NASA Langley, NASA Goddard, Air Force Research Labs (AFRL), and other optical institutes and organizations outside the US are seeing significant improvement to their EO sensor design process and simulation throughput. Single iterations that in the past have taken 3-6 weeks to complete can now be completed within a day, allowing the engineers to rapidly explore geometry, configuration and environment changes. 


  • Integrated, collaborative environment for design and analysis, including all the disciplines and tools
  • Automation of STOP process to significantly reduce time to analyze each iteration
  • Standardized and enforced nomenclature and best practices, across the multidisciplinary team
  • Fully automated results extraction and report generation.
  • Facilitates team and customer design reviews within the single integrated environment, reducing the need for creating “static” discipline-centric presentations


  • Engineers are able to rapidly configure and evaluate EO sensor systems, changing geometry, configurations and environment conditions easily
  • Engineers develop a deeper understanding of the behavior of the EO sensor when they are able to rapidly analyze various configurations and scenarios
  • Significant reduction in model preparation, results extraction and report generation time for each design iteration and environmental scenario
  • Breaking down the barriers between the discipline silos, facilitating deeper collaboration in the multidisciplinary teams and fostering “systems thinking”
