Timestamping issues

When the decoder runs for a longer time, it seems several messages for the same aircraft are issued with the same timestamp.

Suspicions (as of 21 June):

  • restarting the samplicator program used to duplicate UDP feeds helps;
  • messages do not necessarily reach the decoder in chronological order;
  • we should also detect and merge messages seens by several decoders

Possible updates required in patterns.json

Some counterintuitive examples to investigate:

  • aircraft 4d24ca / 9H-VVI (among many others): registered in Malta, out of the Malta range (4d2000 to 4d23ff).
    Does the range need to be edited?
  • aircraft c95000 / 4W-AAL: registered in Timor-Leste, undocumented range (Vanuatu stops at c903ff)
    Does Timor-Leste have a range?
  • aircraft registrations in T2- are assigned to Tuvalu, no range in the patterns.json file. I have two occurrences T2-6965 (7d007c) and T2-6322 (7cd518), in the Australia range (7c0000 to 7fffff), mostly visible in Australia.
    What to think?

@espinielli any hint?
