Goals
Discussion items
Signal Processing Algorithm + tests
- Synchronization board received
- missing some parts (GPS)
- Possible to control camera settings
- Literature review on detection algorithms + some testing
- Possible to predict chlorophyll with radiance
- A little bit uncertainty on who will fly at Hopavågen
Summary of MDR outcomes
- HSI mission is both a tech demonstrator (on-board processing and synoptic agent observations) and with oceanographic science as main motivation
- Q1 2020 Launch is goal
- Satellite shall preferably be a 8-10 PM SSO configuration with backup of 9-11 AM SSO configuration (more available launchers)
- Low chance of detection (clouds) – need to observe April-June (3 months operational is minimum requirement)
- Aim at 8 MNOK total for 2 satellite missions (includes training + integration on campus)
- HSI mission will cost approx. 5 MNOK
- S-band for both uplink and downlink
- NTNU shall at best have full control of uplink or downlink
- Investigate new HSI design (FICS), increase FoV and aperture to increase SNR (light to be captured)
- Relaxes pointing requirements (0.1-1 deg accuracy; 2σ)
- May indicate larger data products
- Add another RGB camera for geo-referencing purposes
- Start testing the current versions of HSI asap
- Level 2 and 4 (scientific and operational respectively) are nominal data products – the rest is upon request from end-user
- Coordinate with AUV groups (NTNU, UPorto), HSI mission shall support their field campaigns (Frøya, Svalbard, Azores)
- We push for a 3U CubeSat
- Compromises implementation of SDR
- SDR would need a new mission design to emphasize it’s link and importance to HSI mission
- Next mission in pipeline: SDR or HSI #2
- 6U has more imaging + comms. flexibility, but will be a bit more expensive (however may include SDR).
- Would like to have access to SDK (+ source code) for components regarding PhD and academic purposes (also align PhD goals with mission success criteria)
- Shall follow IOD CubeSat standard
- Make a comparison of NTNU SmallSat and other competitors (CubeSats and large EO sats)
Onboard Data Processing Pipeline
- Survey of Hyperspectral imaging algorithmsfor ocean application
- Workshop with Ajit («HICO_instructions» file on gdrive)
- Spatial Compression JPEG2000
- Compression analysis for HICO and AVIRIS data,
- work on software adaptation of existing OpenJPEG library for ARM processors ,
- Spectral&Spatial Comression CCSD123
- Compression analysis for HICO and AVIRIS data
- Work on hardware implementation of BIP mode
- Spectral Compression PCA
- state-of-the art study for Hardware implementation of algorithms for eigenvalues/vector pairs
- Anomaly Detection Algorithm
- State of the art study of hardware realizations
- Testing HICO data
- EMSC - Work on software realization adapted for ARM processors
- Prototype – Study of sensor protocols
HW - Julian
- PCBs received. Soldering is almost done (he’s showing it in the meeting)
- All design is on wiki
- Working with Fred to get an optical design that fits the PCB
- Dennis will write the drivers for it
- Milica’s group can then also start working on it
- Optical assembly in clean room is not critical
- Optical design - Still isn’t done
Other things
Someone needs to work on the RGB camera
- Georeferencing
- Focus on characterizing the HSI camera first
- Use that as input to deciding the RBG camera for flight
- Make a student project?
- Amund and Joao/Evelyn think of a master thesis project (COTS-camera) for georeferencing purpose
- Maybe use Fred’s camera as a start
- Doesn’t need to be on-board. Just synchronized
- NUTS has a RGB camera – can we connect it to the Zync-board?
- For satellite flight, any interface should be available for it (LVDS, SPI)
Deconvolution – someone needs to work on it
- Who can do it?
- When we capture data as push-broom, each line will overlap with the previous one. We will have much more lines than we really want (10x)
- Improve resolution along-track (750m) to 40m. Need deconvolution to mash together different lines and improve resolution
- There was a master student working on it, but there is still a lot to be done. Not really much implementation.
- Other options
- Image fusion
- Super resolution algorithms
- Need a master thesis
- Mariusz will talk with Tor Arne about its
Action items
- Unknown User (santora) will talk to Tor Arne about master thesis on deconvolution theories and implementation
- Unknown User (livermor) and Unknown User (amundgj) will work on RGB camera thesis definition
- NKOM: Unknown User (eeide) and Unknown User (garaq) will work on NKOM with Unknown User (rogerbi)
