@zhipengzhang 收的很棒，下次有能力可以尝试把解码的图像数据包上传到SatNOGS DB

Hi Vlad,
You might switch the Norad ID to 66909.

OK! Sorry.
SILVERSAT 16:07-16:13 UTC on 7 el yagi and RTL SDR V4 (manual aiming). Signal +10..+20dB (pulsating every 8 packets) over -95 noise floor. 186 packets caught. Picture fully formed on the third repeat. ( nearly two minutes after transmission start)
Many thanks for precise schedule and all your work.
Nice to see SilverSat back and fully operational !

SilverSat 16:30 -16:35 UTC Picture №21
Got all the picture blocks (46) but missed the very beginning due to local inteference.
This time I used my helical antenna so as I expected - the signal became a bit weaker (up to 3-5 dB) but way more stable as the polarization and orientation of the satellite matched antenna for far longer period of time in comparison to Yagi - got full picture when satellite passed near apogee.
7 turn mobile helical antenna. I placed it on the ground as its reflector hides everything when I’m holding it in one hand and taking a photo with the phone in the other hand

Great work Scott! A bit low over FN41iq to your NE in Rhode Island. Happy to get most of it.

Great job, Bob!
On the chance that some future Cubesat Project Team is reading this thread, please note and with the speed that the SSDV downlink blocks deliver the underlying JPG image, you could easily ramp up the image size to 640x480.
With decent elevation, we are decoding multiple copies of each SSDV frame from these 320x240 images. With a properly functioning radio and antenna, you should have no problem with a larger payload (i.e., a 640x480 image).

Transmission of larger photos will require more time and energy for transmission. If resolution doubles - number of packets might be increased up to 4 times, so it will result in increased single picture transmission time (if only TX timing stayed the same, but it might be possible to make gaps between packets smaller if transmitter’s temperature profile will allow that) and energy (might be critical for 1u satellites - more time to recover batteries.). Also it will be more problematic for partial satellite passes when you can’t see full transmission, so more passes needed to get the full picture.
Just my assumptions from satellite listener’s point of view.
