HyperScape100

The HyperScape100 is engineered to bring hyperspectral capabilities to nanosatellites. This imager is based on a 12.6-megapixel image sensor and a continuous variable filter in the visible and near-infrared (VNIR) spectral range. The Hyperscape100 provides continuous line-scan imaging in up to 32 bands, each with digital time delay integration (TDI).

Features:

  • 4.75 m GSD (at 500 km orbit height)
  • Swath width of 19.4 km (at 500 km orbit height)
  • Simultaneously image up to 32 user selectable bands in the VNIR range
  • Panchromatic plus over 1000 hyperspectral bands available
  • Hyperspectral FWHM bandwidth of 4% or 3% of the central wavelength
  • Hyperspectral OOB energy less than 0.5% of inband energy over the entire spectral range
  • 128 Gigabyte non-volatile ECC storage capacity
  • On-board image processing and compression
  • Comprehensive onboard telemetry and health monitoring
  • Latch-up current monitoring and optional on-board power switch with quick turn-off
  • Inject AOCS/ADCS parameters and time information into data stream
  • Option to integrate pulse per second signal
  • For more technical details see Documents tab below

Applications:

  • Precision agriculture
  • Forestry and land use
  • Energy and infrastructure
  • Coastal monitoring
  • Air quality

Four standard filter options are available, as shown in the Table below. In all cases, the out-of-band transmittance of the filters are less than 0.01% (OD4). A panchromatic band is available only with filter option 4.
