STRaND-1 Telemetry 04-08-2013

STRaND-1 04-08-2013 18:03 UTC

Here is an image from the orbit that STRaND-1 had during this pass. AOS was in the North-East and LOS almost due South. I am puzzled why STRaND-1 is sometimes much stronger when switching to LHCP. This was such a pass and in the images below you can see the difference.

Signal difference between LHCP and RHCP in the beginning of the pass. You can see the difference when I switch between LHCP and RHCP.

Further in the pass and closer as you can see in the signal strength. And again a big difference in signal strength when switching between LHCP and RHCP.

The last image, is the decoded data from the frames that I received during this pass. It looks that the solar panels on the +Y array are producing the largest amount of power. Does this tell something about the fact that signals are stronger when using LHCP.
