Summary

The HyperScape100 is a hyperspectral push-broom imager primarily designed for Earth Observation applications, as a payload for CubeSat satellites. It is based on a CMOS image sensor and custom continuously variable optical filter in the visible and near-infrared (VNIR) spectral range. The HyperScape100 provides line-scan imaging in up to 32 spectral bands, each with digital time delay integration (dTDI). In addition to a panchromatic band, the HyperScape100 has over 1000 hyperspectral bands available with central frequencies ranging from 442 nm to 884 nm.

The optical front-end (OFE) has a large aperture diameter and long focal length within a compact form factor, resulting in a ground sampling distance (GSD) of 4.75 m at an orbital height of 500 km. The modified Cassegrain optical design brings performance to the edge of the object field over the whole spectral range at an ultra-low distortion. The HyperScape100 is engineered to withstand the rigours of the space environment and maintain performance across a wide temperature range. Its compact form factor is optimised for integration into 3U or larger CubeSat structures.

The HyperScape100 imager consists of the following functional components:

  • Optical Front-End (OFE): The xScape100 VNIR OFE is used to focus the incoming light onto the focal plane.
  • Sensor Unit (SU): It consists of the CMOS sensor front-end electronics (FEE) and a continuously variable filter. It also includes the sensor plate mechanics which allows it to be mounted at the OFE's focal plane.
  • Control Electronics (CE): The CE provides control and data interfaces to the satellite bus. It performs sensor control, data handling, data storage, and image processing. It is also responsible for power regulation and management, as well as health monitoring and telemetry.

Applications for which the HyperScape100 can be used include:

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

Some key features of this imager include:

  • 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 (optional)
  • 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
  • Environmental verification based on GSFC-STD-7000
