The TriScape200 by Simera Sense is a red-green-blue (RGB) colour snapshot imager primarily designed for Earth Observation applications, as a primary payload for microsatellites like CubeSats. It is based on a 65-megapixel CMOS imaging sensor with integrated RGB Bayer filter in the visible spectral range. The TriScape200 provides snapshot imaging with a frame rate of up to 30 full resolution frames per second (FPS) at 10-bit pixel depth.

The optics have a large aperture diameter and long focal length within a compact form factor, resulting in a ground sampling distance (GSD) of 1.5 m at an orbit height of 500 km. The modified Cassegrain optical design brings performance to the edge of the field over the whole spectral range at ultra-low distortion. The TriScape200 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 12U or larger CubeSat structures.

The TriScape200 imager consists of the following functional components:

  • Optical Front-End (OFE): The xScape200 VIS OFE is used to focus the incoming light onto the focal plane. It includes a near-infrared (NIR) blocking filter.
  • Sensor Unit (SU): It consists of the CMOS sensor Front-End Electronics (FEE) with integrated RGB Bayer 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 of the Triscape200 include:

  • Emergency management
  • Mapping & geographic information systems
  • Land use
  • Business intelligence
  • Infrastructure monitoring

Some key features of the TriScape200 include:

  • 65-megapixels (9344 x 7000)
  • 10-bit pixel depth
  • Up to 30 full resolution frames per second
  • Ground footprint equal to 14 km x 10.5 km (at 500 km orbit height)
  • Integrated RGB Bayer filter in the visible spectral range
  • On-board image processing and compression capabilities (optional)
  • Comprehensive telemetry and health monitoring including OFE temperature measurement
  • 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
