Topic: HSI HW; Onboard processing; Mission; Downlink of Data; NEX (NASA Earth Exchange)
- Presented the HSI mission (MDR+HSI ver. 6 prototype)
- Emphasizing that our SmallSat is complementary to other (small and large sat) remote sensing missions
- Interested also on the weather-impacts
- Should have in-situ assets to verify AND
- Correlate with Sea-Surface-Temperature (SST) and weather conditions (wind speeds, atmospheric conditions, waves etc.)
- Discussions
- V4 HSI
- He was interested in testing/having a copy of this, wants to use on the desk
- Very fond of the idea of using low-cost COTS components to manufacture the camera
- V6 HSI (prototype)
- Sounds reasonable to go with this design in terms of better SNR
- Easier to process in terms of "what we are looking for"
- Onboard-processing
- Downlinking 2-3x more data (larger image size), should not be a problem in terms of downlink budget
- Careful with the deconvolution processing + radiometric processing on-board the SmallSat, as geometric and atmospheric variables need to be cross-checked carefully (by a person). Having databases on-board is good, but not great for having all the real environmental data correlated with the images taken.
- Spectral+spatial processing makes sense
- He is interested in having our datasets added to the supercomputing simulations at NASA Ames (NEX)
- He loved the idea of very short response time between SmallSat-mission control-potential other agents (UAV, USV, AUV). I said 30 min max until end-user get's the complete data.
- NEX
- We should have a look at the projects and resources available there: https://nex.nasa.gov/nex
- They focus now on using multi-spectral data from GOES-R and GOES-S satellite series: https://www.goes-r.gov/
- Weather monitoring and forecasting
- GEO satellites (3 hrs response time)
- Uses, amongst others, the ABI instrument: https://www.goes-r.gov/spacesegment/abi.html
- Multi-spectral Imager
- 16 channels
- 500 m spatial resolution (visible spectrum)
- Takes full disk images every 15 min
- Takes images of US coast every 5 min
- On-board calibration available
- Also use images from MODIS for ocean color
- Combine all open data for exquisite virtual and scientific simulations with data that correlates (please see resources: https://nex.nasa.gov/nex/resources/)
- V4 HSI
Action items:
- Bring a HSI (v.4) copy to have him have a look
- Look into the NEX projects and resources, use their data and algorithms
- Further discussions with him TBD
- Add this to our observation network?
