Control Actuation
INNOVATION Maintains spacecraft and
interferometer-component formation in
interferometry mission by exploiting its primary
scientific product. Uses these measurements as a
form of real-scene wavefront sensing to infer the
control error towards a formation-control
solution.
Interferometer Output Enhancement

• ACCOMPLISHMENTS
• Formulated control problem for interferometer
  concepts with multiple pairs of apertures.
• Developed spatial-domain and frequency-domain
  processing techniques to estimate interferometer
  control errors.
• Verified feasibility of technical approach by
  testing estimation and control solutions with
  interferometer simulation in fast-prototyping
  environment.
• COMMERCIALIZATION
• Phase II collaboration with specific space
  interferometer mission will enhance technology
  readiness for NASA to consider adoption for
  deployment.
• Separate funding will be sought from DoD to
  transfer technology to space-based
  reconnaissance/surveillance.
• Potential in medical and industrial applications
  will be explored.

Parameter Assessment
Interferometer Control

• GOVERNMENT/SCIENCE APPLICATIONS
• Space science applications to enable space
  interferometer missions for imaging celestial
  bodies and phenomena
• Earth and planetary sciences to enable orbiting
  interferometers to map and collect geo-spatial
  data
• NASA and DoD as customers
• Space-based reconnaissance and surveillance
• Synthetic-aperture-radar (SAR) interferometry
