ARISSat-1 transponder

00:08 UTC I could hear my own signal via ARISSat-1 transponder (eclipse, low power mode)

03:15 UTC CW beacon

field strength over an complete pass (04:51 UTC, 25 deg elevation) – you can see the high spin rate of ARISSat

I compared the spin rate (according to the noise dips per minute) from a pass on Aug 4 to the same pass this morning (Aug 7).

Green line is Aug 04 = 10.5 dips /min = 5.25 rpm
Red line is Aug 07 = 9.5 dips/min = 4.75 rpm

So we can say that the spin rate of ARISSat is degreasing slowly …
