Oliver Jowett f6075212f4 faup1090: Reinstate TIS-B reporting as just the address type is 
not sufficient if there is both TIS-B and Mode S for the same
aircraft.

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)

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)
 2015-06-29 10:06:13 +01:00
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.
 2015-06-28 20:04:09 +01:00
Oliver Jowett 8f08c1b87f Make faup1090 write to stdout, not listen on port 10001. 2015-06-28 19:59:49 +01:00
Oliver Jowett c7722f2b97 Guard against closing clients in a couple of places. 
In particular, not guarding in flushWrites() meant that we
could end up trying to write to an uninitialized writer
(where writer->service == c->service == NULL) and crashing.
 2015-06-26 21:29:54 +01:00
Oliver Jowett 8d1df036ae Don't use DF0/4/16/20 altitudes when DF17/18 altitudes are available. 
The DF17/18 values are generally more trustworthy as they have full
CRC coverage. Errors in the CRC bits of a DF0/4/16/20 message can
result in the contained altitude being attributed to the wrong aircraft.

Oliver Jowett 278448179d Factor out net services so they're not tied to a static array. 
This lets different things dynamically create the services they need,
and sorts out the horrible hacks that view1090 used to make outgoing
connections. Now you can explicitly create a service and tell it to make
an outgoing connection.

This means that view1090 can now just set all the ports to zero (to disable
the listeners), do a normal net init, then explicitly construct the beast
input service without a listener and tell it to make a connection as needed.

Oliver Jowett 21bdc45bf0 Tweaks to noise measurements. 2015-06-16 10:13:25 +01:00
Oliver Jowett 7d4eaf6a48 Don't emit stale alt/speed/track/pos (more than 30s old) even if 
they were updated since we last emitted a message.
 2015-06-16 01:38:44 +01:00
Oliver Jowett 4f861f653a Track age of heading/speed/altitude; use this when deciding what to emit in FATSV format. 2015-06-15 23:13:04 +01:00
Oliver Jowett 4d697ac61d Emit capitalized hex in avrmlat output. 2015-04-18 11:21:09 +01:00
Oliver Jowett e9378fb1c5 Fix endian issues in timestamp input/output. 
This affected Beast input/output, and AVR output in --mlat mode.

Works on a little-endian host, should work on a big-endian host but
I don't have one to test with.

Probably fixes #44.
