"Quartus enthusiastically tackles problems as they occur. They even found errors made by former analysts! Overall, it was great to work with them.”
– Charles Baker, LROC Thermal Director, NASA GSFC

CASE STUDY 

NASA SBIR Phase I & II - STOP Analysis Validation

Quartus is working to accelerate the development of custom optical payloads with STOP analysis model validation

  • Based on the SAGE IV Pathfinder telescope, validation will be used across projects going forward

    • SAGE IV Instrument fits inside a 6U LEO CubeSat

    • FOV: 1 degree (60 arcmin) 

    • Aperture: 42 mm clear aperture

    • Stray light rejection: < 1.0E-4 PSNIT at 0.5° outside the FOV

    • Reflective system is near diffraction limited 

  • Validation of models done beyond one program's use case, allow for low-risk extrapolation of designs/models for new instruments

​Design paradigm can be leveraged on new optical instruments with various architectural changes, such as:

  • Key parameters (aperture, FOV, filters, detectors, etc…)

  • Reduction of complexity (reduce complex stray light suppression, use only back end as a proven 4° FOV TMA, etc...) 

  • Use developed mounting method for alternate optical component (include refractive elements, gratings, etc...)

  • With early engagement, new science instruments could jump from concept to flight rapidly
