OH7LZB, the operator of aprs.fi has written a good explanation of
duplicate and delayed packets at

I can resonate with this because I had been struggling with bad APRS
position reports for a long time.  Bogus lat/long, munged callsigns,
delayed reports (some by 24 hours) and there wasn't any one single root
cause.  Nice to see the explanations and all in one place.
