Action items
- Not complete (week 44) Unknown User (orlandic) and Unknown User (joaoff) Determine the precision on numbers for implementation in FPGA; custom-made precision (24/32 bit); Match the Matlab precision (64 bit) with the image (16 bit). Floating point vs. fixed point. Computational speed.
- Not complete (week 44) Unknown User (joaoff) Actual performance of real HSI camera (take raw images); subtract black frame; test different viewing angles to reference target and exposure times - how it affects SNR; model variance of signal-dependent noise.
- Not complete (week 44) Mariusz Eivind Grøtte Look into how GSD<100 m should be achieved, currently it is at 248 m with current slew rate required and optical characteristics
- Not complete (week 44) Mariusz Eivind Grøtte Make an energy budget and duty cycle for observations/comms.
- Not complete (week 44) Mariusz Eivind Grøtteand and Unknown User (joaoff) Iterate on HSI memo to Steve
- Not complete (week 40) Mariusz Eivind Grøtte Get preliminary results from EOIR tool in STK (or MODTRAN) on "what can we see from space"
- Not complete (week 40) Unknown User (rogerbi) A cost benefit analysis of power usage vs compression for comms.
- Not complete (week 40) Unknown User (sivertba) Find a student to do thermal analysis and coordinate with Mariusz
- Not complete (week 40) Give feedback on Gantt chart (ALL) - Still want a list of activities from each - respond to emails
Introductions to Gara (new PhD student, Torbjørn Ekman)
Data from HSI
- Working on HSI report (UAV test flights)
- Doing SNR calculations (raw images)
- Trade-off between SNR and resolution in binning
- SNR doesn't tell the story (just a small part of it)
- Fred's paper
- Second order effects (800 nm and up)
- Mitigation for these effects
- Sivert: invariant areas/objects in the EM spectrum,
- How to utilize that for calibration
- Rayleigh scattering explained
Hardware
- SD-card and 1 GB storage
- HSI data transmitted thru serial/CAN directly to Radio (providers will fix the interface)
Software
- Testing projection core
- Comms. for memory
- Will test this on the test development board
- Harald sent email on modifications to EMSC
- What are the consequences on implementation (Milica & IdleTechs coordinate)
- Bitwidth for loadings and data need to be established
Communications
- None
Mission Design
Actions ahead
- End of this year we need specs for the public tender
