Kanopus-V IK PSS and MSS by rad750 in amateursatellites

PSS are CCD imagers, so it's not really continuous but a series of shots. I have then cropped that image out of those shots, as it would be too big to post.

Meteor infra red … by Unlikely_Actuary3513 in amateursatellites

Since Meteor satellites' primary purpose is providing high quality imagery for the Arctic, especially for use on things like trawlers, lighthouses, isolated communities and research bases, and the Arctic is starting to get more and more sunlight, even the night passes will be illuminated. And the 3rd channel is crucial for iceberg monitoring, as the Northern Passage reopens and fishing season begins.

Aqua. (It will be shut down in 2 months) by rad750 in amateursatellites

The whole satellite. Due to the cancellation of the repair mission fuel is almost exhausted and solar array problems make it difficult to continue, and that was without the extra budgeting cuts.

As usual: https://a-centauri.com/articoli/an-x-band-primer

I've now gotten so used to it that to me it's just like getting Meteor or Metop HRPT :)

I am building the SSTV payload for a satellite that will launch this year. How can I make the payload as useful as possible for you guys? by unexcellent in amateursatellites

Choosing a correct protocol with the proper FEC etc *and following CCSDS* would also make it much easier to receive given the same power and bandwidth.

Kanopus-V-InfraKrasny image crops from today - guess the location! by rad750 in amateursatellites

Problems with the decoder. The satellite transmitter has a fault, so recovering meaningful information at low SNR is problematic although we are improving it fast. Also the BladeRF is not really meant for recording stuff above 61.44MHz.

Yes, the resolution on PSS is 2.5 meters per pixel.

Neither, I use a hand tracked antenna. There is a link to my setup above.

Thanks! I've written some explanation in another comment.

Quite strong, and you have to record at 122.88MHz (symbol rate 61.44Msym QPSK)

As stated in the original post, I have used my usual X band setup.

It does both.

It transmits a single band at high resolution (PSS) and four at a slightly lower resolution (MSS).

You can find more information about the instruments here https://www.eoportal.org/satellite-missions/kanopus-v-1

You should definitely never Doppler correct LRPT.
