Hi
FUNcube packets are accepted up to two days after they were received by the dashboard.
We use the sequence number and frame type to determine the ‘satellite time’ since the epoch.
We can use these packets to back fill any missing ones and ‘score’ them for the user.

Normally, I decode telemetry live from the satellite and upload it immediately. I have an RTL-SDR attached to my Android phone and use SDRTouch to demodulate the FM signal feeding the headphone out to my laptop running FoxTelem to decode the frames and upload it through my home's Wi-Fi.
However, with the weather turning and the difficultly of getting everything set up, I was wondering if there are any issues with recording the audio or IQ signal on my phone during the pass and feeding it into FoxTelem from my phone later. Does it use my computer's local time or expected to be the live stream, or does it just rely on the time stamp in the decoded packets for ordering the telemetry data whenever it's received?
And on that, if I can decode later, is there a time limit I should follow for decoding older data? If I captured a satellite pass in the morning before leaving for work, but didn't feed it into FoxTelem for decode until the evening when I get back home?
And lastly, I know it's a different group operating it, but I'm curious if it's a similar policy for AO-73, the first FUNcube sat for decoding packets delayed from their capture time.
Thanks for the info! 73s, Loren AG7NC _______________________________________________ Sent via AMSAT-BB@amsat.org.
