Some algorithms (CCSDS etc) are being implemented on hardware – being tested. Preliminary results are promising
JPEG2000 with reversible wavelet transform
Some problems with prototype that Julian will try to fix
Once Joao has more time, he will look into some more algorithms
Satellite bus update
OpenCosmos demo last week – Hardware-in-the-loop software/hardware
Positive to ADCS collaboration
Risk workshop
First iteration: Thursday 13-14
Second iteration: when both Joao and Sivert are available
From then on, every other week during weekly meeting (15 minutes update)
Hopavågen
IMU and GPS software/hardware integration are pretty much done.
will meet with Maritime robotics today to see about fitting the payload into their UAV.
Joao has booked a big van for the testing
Sivert will learn more about it
Rest of the week should be final payload assembly and testing camera settings
HSI Camera V6
There are a couple of outcomes:
Spatial resolution is improved to 250 m*58.5 m per pixel.
Please look at Figure 7. for the conclusion on performance comparison between the different versions
Hence the effect of higher SNR and optical resolution gives the win to V6 (SNR vs. optical resolution is a trade-off)
This shows that decision should lean towards V6 when we think performance
Decision on slit width (25 vs 75 um) needs to be done
Constraints of cost, size (we will have to go from 3U to 6U CubeSat structure), launch cost for satellite etc.
Opto-mechanical issues and coating
Version 6 does not perform remarkably better in terms of SNR (number of photons) however it has increased satisfactorily (V6 (75 um) twofold compared to V.4, V6(25 um) x1.4 compared to V4)
Mission update
Design and sizing of the reaction wheels (worst case)
