- There are still a lot of confusion and questions regarding the Hardware interface of the payload
- clear benefit between multispectral and hyperspectral should be defined
- benefits of multispectral
- This is how the spectral resolution of most OC satellites
- algorithms and models are based and tested on this spectral resolution
- We will achieve a better signal to noise ratio using bands i.e. binning more signals together
- The HABsat-1 mission claim: "Research has shown that hyperspectralcustom narrowband multispectral imagers with radiometric thermal imagers are the preferred instruments for predicting, detecting, identifying potential HABs in the oceans"
- Will produce less data, alleviating the burden wrt. storage requirements and downlink speed
- This is how the spectral resolution of most OC satellites
- benefits of hyperspectral
- The mission is supposed to be hyperspectral
- We can take a more statistical approach as opposed to relying on "perfect" bands
- "To identify phytoplankton functional groups, hyperspectral data with 5 nm resolution is required"
- "Research has shown that hyperspectral or custom narrowband multispectral imagers with radiometric thermal imagers are the preferred instruments for predicting, detecting, identifying potential HABs in the oceans"
- Greater flexibility wrt. to potential changes in operation
- benefits of multispectral
- There is a clear distinction between classification and target detection. Both are applications within hyperspectral image processing, but not dependent on each other.
- Could use classification schemes to determine regions of interest, but at an undetermined power/computational cost.
- Even though not clarified in the meeting the CCSDS-123 is the better choice for lossless compression given TRL for our mission when compared to JPEG2000
