Spectral Imaging Solutions for

Commercial Applications and the New Space Economy


Constellations of small satellites represent beneficial platforms for earth observation, atmospheric science, and Space Situational Awareness

Headwall has demonstrated space experience. Small, lightweight, hardened versions of its customized commercial-off-the-shelf (COTS) hyperspectral imaging sensors are in orbit now. These imaging spectrometers represent reduced-risk solutions for a wide range of space missions.

Hardened Spectral Payloads

Headwall's customized COTS hyperspectral sensors are designed for use on small satellites to deliver high-resolution image data in the following spectral ranges:

  • UV-VIS (250-500nm)
  • VNIR (400-1000nm)
  • Extended VNIR (550-1700nm)
  • NIR (900-1700nm)
  • SWIR (900-2500nm)

Spectral Image Data: Perfected

Headwall specializes in both hyperspectral data acquisition and exploitation by providing imaging sensors and software solutions covering hundreds of spectral bands from UV-VIS to SWIR. Spectral data can be used for:

  • Earth observation (agriculture, mineral exploration, disaster monitoring)
  • Atmospheric science, air quality/pollution, and greenhouse gas detection
  • Space Situational Awareness


Air Quality & Greenhouse Gas

High-resolution spectral imaging sensors have the ability to collect data useful for monitoring air quality and pollution (including greenhouse gas emissions). Headwall provides imaging sensors such as the following that target specific spectral ranges with very high resolution:

  • 420-490nm; 0.1nm spectral resolution
  • 1560-1670nm; 0.34nm spectral resolution

Imaging Photosynthesis

A key advantage of Headwall's customized COTS approach is that it can produce mission-specific hyperspectral imaging sensors 'tuned' to high-resolution spectral bands. Headwall's imaging sensors measure solar-induced fluorescence:

  • 670-780nm; 0.1-0.2nm spectral resolution
  • 755-785nm; 0.1nm spectral resolution
