Action items

  •  
  • 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. 
  • 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.
  • 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
  • Mariusz Eivind Grøtte Make an energy budget and duty cycle for observations/comms.
  • Mariusz Eivind Grøtteand 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
  • No labels
