                      Technology Goals

   Reduce payload size (sensors, pointing systems, mirrors)
     Maintain line-of-sight stabilization for high spatial resolution
      at GEO
     Reduce detector pixel size, improve dynamic range
     Improve optical efficiency, grating throughput
   Enhance science return
     Enable retrieval of additional policy-relevant products and
      extended spatio-temporal products

                                 Multi-Slit Offner Spectrometer
                             PI: Timothy Valle, Ball Aerospace and Technologies Corp.

• Develop a Multi-Slit Offner Spectrometer for
  geostationary (GEO) coastal remote sensing and
  test it in an operational environment to
  demonstrate TRL 6.
  - Key technologies include a butcher block order
    sorting filter and a blazed, curved grating.
  - A Multi-Slit Offner Spectrometer, employed
    in a geostationary remote sensing payload, can
    accomplish the ocean color mission with a small
    package, fast revisit time, and high SNR by
    producing hyperspectral images at multiple
    positions simultaneously, thus, reducing the
    risk for Geo-CAPE Event Imaging.

     scaling issues and is capable of operation over the
     flight instrument spectral range (0.26 µm to 15 µm)
   - Instrument operation in a space like thermal-vacuum        From geostationary orbit the PanFTS instrument will make hourly
     environment demonstrating simultaneous UV-Vis and IR       measurements of atmospheric composition with wide spectral sensitivity
