The MultiScape200 CIS is a multispectral push-broom imager primarily designed for Earth Observation applications, as a primary payload for microsatellites like CubeSats. It is based on a CMOS imaging sensor and a 7-band multispectral filter in the visible and near-infrared (VNIR) spectral range. The MultiScape200 CIS provides continuous line-scan imaging in up to 7 spectral bands, each with digital time delay integration (dTDI).
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 MultiScape200 CIS 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 MultiScape200 CIS Imager consists of the following functional components:
- Optical Front-End (OFE): The xScape200 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 7-band 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 MultiScape200 CIS include:
- Precision agriculture
- Forestry and land use
- Energy and infrastructure
- Coastal monitoring
- Air quality
- Resource and infrastructure monitoring
Some features of the MultiScape200 CIS include:
- 7 spectral bands in the VNIR range
- 12-bit pixel depth
- 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
