MultiScape100 CIS - Simera Sense - SmallSat Catalog - Orbital Transports

MultiScape100

The MultiScape100 CIS is designed with a single goal in mind, to capture the earth in greater detail, more depth and a wider range of spectral bands within a 3U and 6U CubeSat form factor. This imager is based on a global shutter CMOS image sensor and a multispectral filter in the visible and near-infrared (VNIR) spectral range, each with up to 32 digital time delay integration (TDI) stages.

Features:

  • 4.75 m GSD (at 500 km orbit height)
  • Swath width of 19.4 km (at 500 km orbit height)
  • 7 spectral bands in the VNIR range
  • 128 Gigabyte non-volatile storage capacity for up to 18 000 km strip (at 500 km orbit height)
  • On-board image processing and compression capabilities
  • 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
  • Resource and infrastructure monitoring

The signal-to-noise ratio with a selection of TDI stages, at an orbit height of 500 km is shown in the Figure below. An at-aperture radiance function of 100 W·m-2·sr-1·µm-1 is assumed across the spectral range for all of the SNR values. The transmittance of each band is also shown.
