Meteor M2-4 on board time error
current time of pass should be used to generate the geo map as the onboard clock on Meteor M2-4 is corrupted
This is not possible, you will not now the timestamp in a ms resolution. Also start of the recording of the pass is not equal to the timestamp of the first decoded packet.
Why couldn't you generate the geo map based on the pass time and orbital elements. The on-board time is unstable, and the geo map does not reflect the correct satellite position

Because it is not possible to now the pass time. There is not reference without the timestamp from the packet
But as I said it is not punctual. Between the start of the recording and the actual first decoded valid packet, the elapsed time is not known.
No, there is no such option. I am sure timestamp will be fixed soon on the satellite.
Will have a look at it. I don't have LRPT receiving system right now, but I asked some forum members to provide some cadus
So I have got a cadu file, with satdump the overlay is slightly off, but meteordemod draw it perfectly. Can you upload a file containing the decoded pictures, the cadu and tle file? You can use swisstransfer or something similar to transfer the files. Thanks
Ok I know I have the correct tle file Offline processing a pass recording with satdump causes it to crash when generating timestamps I will upload a cadu file as soon as I can Is the cadu you have recent? This seems to have started happening last week and others are having the same issue thanks
