Summary

The cosine Remote Sensing HyperScout 1 is hyperspectral imaging camera with VNIR channels (450-950 nm) for nano, micro and larger satellites.

The athermal telescope system of HyperScout product line is based on a monolithical structure. The product uses a CMOS sensor-based VNIR FPA and a spectral filtering element to separate the different wavelengths.

A multispectral filtering element and microbolometer are used in TIR FPA. The in-flight debugging of the BEE/OBDH subsystem is performed using ICU as the contact point. The ICU can also be used to power down each of the components. The data housekeeping is logged during the idle state of the system.

The BEE functions include

  • distribution of clock, power, telemetry and commands between the units
  • serves as the latch-up protected electrical interface to the spacecraft.
  • controls the detector and serves as the data and control interface, providing clock timings, frame rate control, exposure and gain control
  • merges the data acquired with the platform ancillary information to create L0 data, which is stored in the payload Mass Memory Unit (MMU)

The OBDH functions include

  • Two modes: acquisition and data processing (if required)
    • Acquisition mode, data will be transferred from the BEE into the memory of the OBDH, which is written to the MMU via SATA.
    • Data processing: the data is retrieved from the MMU and processed in memory on the OBDH

The MMUs of the payload are used to store the acquired L0 image data and processed data. For accelerating machine vision tasks, the Vision Processing Unit (VPU) can be equipped optionally with any of the variants of HyperScout products.

The VPU allows in-orbit real-time execution of deep learning tasks such as agricultural monitoring, cloud detection, hazard identification, radiometric processing, etc

Applications

Hyperspectral imaging applications for Nano, micro and larger satellites.

Key features

  • VNIR channels
  • Compact reflective telescope
  • Large storage capacity to enable high duty cycle to overcome the platform storage and down-link bandwidth limitations
  • Flexible customization of operating modes
  • different levels of onboard processing and data manipulation available to provide the flexibility either by applying full processing or by selecting sub-spatial or sub-spectral regions from the data stored on the HyperScout’s mass memory unit.
  • an app-like upload environment available for the user to deploy new algorithms and run them for in-orbit demonstration and operations
  • a deep learning tailored environment for deployment of the latest Artificial Intelligence (AI) algorithms in space
  • a ground processing tool that contains the latest machine vision techniques developed at cosine to make sure the user can process the spectral data, even when the platform attitude information contains large uncertainties, and to apply the latest radiometric and straylight correction algorithms that cosine developed for larger missions as part of the ESA Copernicus program.

Customizations

Flexible customization of operating modes is possible. Customization can also be based on in-orbit mission constraints.

Flight heritage

The system has achieved flight heritage with the first HyperScout 1 launched in February 2018 as part of a demonstration mission with ESA TEC/MMO, and it is still operational.

Manufacturing

  • Development facilities
    • Optical and electronic integration spaces for development of measurement systems such as hyperspectral, thermal, and altimetric instruments
  • Cleanrooms
    • Separate cleanrooms for plate cleaning & inspection, plate stacking & mirror module integration, optical development & integration, testing and quality control
    • Facilities are used to develop techniques for quality control such as fringe reflection techniques, interferometric analysis, and laser scanning
    • Multiple in-house robot arms setups perform all handling of the stacks, including stacking and discarding plates which do not meet the requirements.
  • Testing and qualification of optical, opto-electronic and electronic (sub)systems
    • Testing of high-power lasers, testing under vacuum and at lowered or elevated temperatures, if necessary, under cleanroom conditions are available
    • Environmental testing laboratories for shock testing, vibration testing and thermal vacuum testing to qualify equipment for space and other extreme environmental conditions are available
  • Production facilities
    • Measurement systems are developed according to the requirements, including hardware and software
    • Integration of one of the measurement systems into the customer’s system, such as production line, laboratory automation system or in the field is available
    • Measurement system is fully documented and delivered including instructions, on-site commissioning, and training
    • Lead time: Depending on the requirements resulting from the environment in which the system will be used, production of the first unit(s) can take between a month and a year
    • In-house building of one-off systems and small series are available. For larger series, the production will be organised with the partners
