Awesome work! https://t.co/Ln9cOGM0okr00t @r2x0t
THIS. IS. JUST. AWESOME. !!!
This is video decoded from the 8455MHz high rate downlink @uhf_satcom received yesterday. All the work on the decoder and data analysis really paid off in the end!
Video shows solar panel of Chang'e-5 glistening in the sun and dust floating around. https://t.co/FKc92kgskl

Last night's Chang'e 5.
@coastal8049 list:
Orbiter-B - 8463.7MHz (decoded)
Orbiter-A - 8571.2Mhz (detected)
Lander - 8455MHz (no signal)
AZ and EL offsets needed to correct SpaceTrack elements. As much as +7 deg AZ and -1.5 deg. EL. Offsets were changes before and after TCA. https://t.co/5CKAXPxevV

More X-band wonders coming out of the lab today. A VE4MA choke ring made out Aluminum to reduce system weight. Next is the depolarizer and transition. Goal ultra light dish and feed for telescope mounting. https://t.co/1POcDAXFHe

This is the high speed data downlink, 2.5MSym/s BPSK, CCSDS framed, but not using APIDs. Uses some custom protocol on VChan 38. It was very busy earlier, now it's mostly idling with some basic telemetry.
This looks like 8 channels of accelerometer data, some changes are visible: https://t.co/3LigSvKfqs https://t.co/0frT5rixkk

Chang'e 5 Downlink on X-Band centred on 8455MHz, a lump of fast wide band data! https://t.co/Eye0cMFFCf

Feed center check with laser bore sight in custom self-centering printed adapter plate!
Seems there is room for improvement.
WIll install some turnbuckle threaded rods to allow adjustment per feed leg. https://t.co/2N0hnpRgrh

Mars and Saturn in June
It’s getting hot and atmospheric conditions are not the best for astrophotography, however stacking 5000 images does help a bit with the variable focus.
April Planets with some nice Glass
Spent some time with the big gas planets and Mars. Mars is closest to Earth since 2007 and is still pretty hard to see. Jupiter turned out nice. Saturn was a bit out of focus, seeing was not too good. … Continue reading
