Oliver Jowett 25ea6d398b Overhaul mode A/C matching to be much cheaper. 
The old matching process which tracked mode A values as pseudo-aircraft
got very, very expensive with a large number of mode A/C messages (and
with lots of single-bit errors, which seems common with a Beast doing
the reception)

Instead just count A/C messages directly into a 4096-entry array (which
is very fast) and periodically scan the mode S aircraft list to see if
we can match anything up (which is fixed overhead + cost proportional
to the number of mode S aircraft)

Oliver Jowett 14a003710e faup1090: Track Comm-B ACAS RA separately to ES ACAS RA as it's useful to see both reported. 
Fix repeated reporting of ES ACAS RA reports.

Oliver Jowett abc30ff656 Increase the TSV packet size to accomodate all the extra data recently added. 2016-09-22 15:33:21 +01:00
Oliver Jowett 32c8358bc1 faup1090: Reinstate TIS-B reporting as just the address type is

aircraft.
 2016-09-22 13:53:40 +01:00
Oliver Jowett df9648911e faup1090: Don't bother with the tisb field now that we have addrtype. 2016-09-16 11:19:26 +01:00

Oliver Jowett 7c1fed98d2 faup1090: entirely blank (all spaces) idents are not interesting 2016-09-15 15:09:35 +01:00

Oliver Jowett 0ae2c5efc8 Emit addrtype in json output. 2016-09-14 17:01:07 +01:00
Oliver Jowett 1958b23a93 Tweak the on-the-ground conditions a little. 2016-09-02 18:46:48 +01:00
Oliver Jowett 303d3c3fef Make faup1090 emit iSource to say where the ident came from. 2016-09-01 19:11:33 +01:00

Oliver Jowett 954034855a Make faup1090 emit some interesting messages when they occur. 2016-08-28 01:29:37 +01:00
Oliver Jowett 54ca2c7fb2 WIP big rewrite of message decoding / aircraft tracking. 2016-08-27 14:34:14 +01:00
Oliver Jowett 36a5c16dd2 Initialize from static "zero" messages rather than using memset. 2016-08-26 21:39:39 +01:00
Oliver Jowett e4ceea33da Disable the internal webserver at build time. 2016-07-10 11:56:31 +01:00
Oliver Jowett da437b3295 Set the socket buffer to the size of a HTTP response. 
This gives us a better chance of the response fitting in a single
write() call (if it doesn't, it's going to get truncated, because
the internal webserver is really simple)
 2016-07-02 10:51:23 +01:00
Oliver Jowett 22c90415be Check we got a full read when serving local files over HTTP. 2016-07-02 10:50:55 +01:00
Jon Williams 94706763e5 fix compilation on OpenBSD 2016-03-31 13:25:32 -04:00
Oliver Jowett 85aa200947 Extra paranoia for --aggressive mode: only forward 2-bit-corrected messages 
via paths that allow the recipient to see that they are 2-bit-corrected
i.e. raw or beast output in --net-verbatim mode only.
 2016-03-03 12:39:01 +00:00
Oliver Jowett 214bc0e587 Treat zero-or-missing signal levels as "no information" and don't include them in RSSI. 2016-02-24 11:55:01 +00:00
Oliver Jowett eb16ac2028 Fix some termination issues. 2016-02-16 13:05:03 +00:00
Oliver Jowett a2eb71d49a IPv6 support (in theory). 
Fixes #87.
 2016-02-16 13:00:55 +00:00
Oliver Jowett 2b466535de Support multiple listening ports per listener type. 
Beast input defaults to listening on both 30004 and 30104.
Drop the FATSV listener entirely (use faup1090 for that)
Ignore --net-beast.

Oliver Jowett c4e162287d Oops, sprintf -> snprintf 2016-01-21 20:22:18 +00:00
Oliver Jowett d9eec668cf Track what data we got via TIS-B, report it as such. 2016-01-21 19:42:37 +00:00
Oliver Jowett ecbdbf23d6 Never forward mlat via SBS or raw output; it is no longer identifiable 
as mlat when forwarded on those paths.
 2016-01-21 17:48:06 +00:00
Oliver Jowett 9479a5c9be If --hae is passed, report altitudes as HAE where available, with a H suffix. 
This affects interactive mode and SBS output.

Oliver Jowett 45d645a864 Default to not forwarding mlat messages. Add --forward-mlat option to enable it. 2015-07-03 21:56:23 +01:00
Oliver Jowett 51b5f4af24 Include mlatFlags in aircraft.json. 
This requires expanding the line-buffer margin too as we can produce lines >256 chars now.

Oliver Jowett b793f83a29 Rewrite and fix heartbeat code. 
The old logic had a number of problems, including:

 * sending heartbeats on all service types if any type needed
   a heartbeat
 * sending a heartbeat multiple times a second if there was a
   service type that was idle but didn't generate traffic when
   an empty message was sent (e.g. FATSV)

Rewrite it all so that heartbeats are explicitly tracked and handled
per service type, rather than by sending a dummy message.

Also switch to mode A/C messages for the beast/raw heartbeat, as
it's a bit more compact and less likely to mess with Mode S state
(an all-zeros Mode S message actually looks valid)

Oliver Jowett 12a7d45e75 Mlat synthetic message detection. 
Notice synthetic mlat messages by looking for messages with a magic
timestamp value. If they arrive, tag the derived data as mlat-derived.

Don't include mlat-derived output in FATSV output to avoid loops.
