Oliver Jowett f9ed7e4a97 More time_t -> milliseconds conversions.
This lets us support fractional net flush times among other things, which is handy.

Oliver Jowett 474fe45256 Don't mark undecodable altitudes as ALTITUDE_VALID when decoding. 2015-02-09 22:53:18 +00:00
Oliver Jowett 54677f3ae0 Don't try to correct >1 error in DF11.
We already do this check when scoring a message for the demodulator,
but there are other paths that can feed us a message so also do the
check in the main decode path.

Oliver Jowett 07a39331c9 Changelog mostly to bump the version to reduce confusion. 2015-02-08 23:11:50 +00:00
Oliver Jowett 25ac2d044d Increase the onehit TTL a bit, 30s is a bit too aggressive. 2015-02-08 22:46:44 +00:00
Oliver Jowett b313834338 Make the is_number regex accept numbers beginning with -0
Also ends up simpler, too - originally I was trying to avoid accepting
e.g. "+0" or "-0" but that's not really a big deal.

Fixes #14

Oliver Jowett 4ecd6958a1 If we squelch the first message from an aircraft, emit it when we see a second message.
This is possible now that the SBS output doesn't rely on the global block timestamp;
the output will look like this:

MSG,8,111,11111,4AC954,111111,2015/02/08,17:57:53.917,2015/02/08,17:57:53.936,,,,,,,,,,,,0
MSG,7,111,11111,392AEB,111111,2015/02/08,17:57:53.744,2015/02/08,17:57:53.936,,15375,,,,,,,,,,0
MSG,8,111,11111,392AEB,111111,2015/02/08,17:57:53.917,2015/02/08,17:57:53.936,,,,,,,,,,,,0
MSG,6,111,11111,800387,111111,2015/02/08,17:57:53.919,2015/02/08,17:57:53.936,,,,,,,,4745,0,0,0,0

where the "receive timestamp" (first time column) goes backwards to reflect the original reception
time of the delayed message, but the "forwarded timestamp" (second time column) reflects the actual
forwarding time.

Oliver Jowett c0af448efa uint64_t (even at 12MHz) isn't going to overflow any time soon, don't worry about wrapping. 2015-02-08 17:59:20 +00:00
Oliver Jowett 9c2f236463 Object files depend on *.h 2015-02-08 17:58:46 +00:00
Oliver Jowett 4e177c2d64 Store computed reception time in the message struct so we don't rely on
the message being emitted immediately.

Fix computation of reception time so it's more sensible (the block timestamp
is some time after reception of the _end_ of the block, not the start) - this
means that message-emission times are always later than message-reception
times in SBS output, which is a bit more sensible.

Use clock_gettime in preference to ftime.

Oliver Jowett 1584955080 Be more aggressive about removing aircraft where we have seen only 1 message. 2015-02-08 14:37:35 +00:00
Oliver Jowett 20407e5378 Don't emit SBS output with non-ICAO addresses (fixes #9) 2015-02-08 14:30:10 +00:00
Oliver Jowett 899c51ce85 Only emit network messages once we have seen two of them
(except in --net-verbatim mode, where we emit them all)

Move aircraft tracking into track.[ch].

Clean up references to "interactive mode" when tracking
aircraft - we always track aircraft, even in non-interactive
mode.

Oliver Jowett 26feb1d078 Add some testing code that looks for ambiguous syndromes that
could confuse the partial correction used in DF11.

That code shows that yes, there are ambiguous syndromes in the
2-bit correction case only, so disable corrections of more than
1 bit in DF11.
