Goals
Discussion items
| Time | Item | Who | Notes |
|---|---|---|---|
Action items
- Evelyn Livermore Look into GANTT-chart
- Evelyn Livermore and Unknown User (joaoff) looks into optical simulations and how to do a sensitivity analyzes there.
- Unknown User (julianve) needs the distances between lenses from Fred.
- Evelyn Livermore Will start work on the platforms and also trade-off analyzes.
* Follow ups on previous milestones (please focus on these, we need to clean up and not forget what we have in the past already!)
* Status
* HSI
--> Joao has uploaded the HSI-report. Presented during the meeting. Promising results, but need ground truth.
* Hardware
--> Julian have started with a new 3D-design. Making a new casing while keeping distances between lenses. He is a bit stuck since Fred is incommunicado at the moment. Evelyn has some ideas on how to analyze and derive info on distances between lenses and so on. PCB is on hold until the mechanical design is in place. Have added SD-card + USB-connectors. The prototype will be good for desk work and drone. Then we expect some changes to the flight model.
Jan Otto stresses that a working model should be made as soon as possible, even if non-complete, sub-optimal and so on.
Issues with Altium server going down...
* Software
--> Testing projection phase. Working with students.
* IdleTechs
* Communications
--> Funding for ground station is secured. Work will be commenced soon.
* Actions ahead
Minutes
Round around the table
On the Action list
Unknown User (rogerbi) A cost benefit analysis of power usage vs compression for comms. --> This item will be closed for now, must have implementations and more knowlegde about algoriths and components yet.
Fixed/floating point: WIll be discussed later today.
HSI tests: Joao does not have the camera now. Fred is on vacation. Will have the camera after newyear?
Julian have been away, will pick up tasks now
Joao discussing SNR with Harald
Evelyn will look into the GANTT chart and perhaps move it to a better place. Can Djura be used, integrated with Confluence.
Other topics
Joao brings up the fact that weekly meeting takes significant time.
Torbjörn brings up that we should meet often, but short.
At least we need to shape up the form of the meeting to keep them timely.
Roger informs on status on platform.
From Mariusz:
Mission design
* Working on EOIR tool in STK, future:
* May use for calibration of HSI images
* Determine what we can see
* Compare with other HSI data (and SNR)
* Challenges: Having a lot of trouble. my PC is way too slow. Might need a stationary PC.
* Future:
* Look into precision control for SmallSat (as we shall expect errors on ground).
* Make a .m script
* Theory vs. practice analysis
* Let me know if any of you need to know some requirements + numbers etc.
* Apart from this status, the concept document is updated (sent out yesterday on NTNU SmallSat email)
Can you also look at the Gantt Chart?

Three points to emphasize from my side:
1) the Gantt chart is made for everyone so everyone should have a look at it, give feedback and suggest tasks for their own part as well as estimated time for those. It has been almost 1.5 months now and I haven't received feedback. My point is that it should not be a one person-thing. This could have been done earlier.
2) Unknown User (joaoff) if we have SNR=172 at let's say 550 nm, then we should expect SNR=15-20 for the water signature we are looking for at that specific green band. What do you think?
3) Unknown User (julianve) were not the dimensions that I gave you sufficient, if not, then what implications did you have with those?
