Fix uc8 lookup table allocation size.
 2017-02-03 00:36:33 +00:00
Oliver Jowett cf9e3005e8 Add a bladeRF SDR type. 2017-02-03 00:30:42 +00:00
Oliver Jowett 75b221c0e3 Lots of refactoring to move the SDR-type-specific bits out of the 
main code and make them optionally buildable.
 2017-01-27 17:30:40 +00:00
Oliver Jowett 52464b97c1 Remove internal webserver code entirely. 2016-12-29 18:35:35 +00:00
Oliver Jowett 6336611bc7 Turn on mode A/C if a Beast connection asks for it. 
Add a --no-modeac-auto option to disable this.
 2016-12-29 17:56:32 +00:00
Oliver Jowett 4bb070be50 Add support for radarcape type 5 (receiver position) messages. 2016-12-27 19:07:10 +00:00

Rearrange the meaning of the measured power level to be consistent
with the signal level.

Oliver Jowett d3fad32d5e Merge remote-tracking branch 'upstream/master' into dev 2016-10-14 21:35:31 +01:00
Oliver Jowett f6b1b94c7d Use ncurses for interactive mode (reduces flicker on slow connections a lot!) 2016-10-11 20:37:28 +01:00
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)
 2016-10-11 18:00:11 +01:00
Oliver Jowett 60f1f3bcb6 Table-ize the Mode A to C conversions, add a Mode C to Mode A conversion function. 2016-10-11 17:57:25 +01:00
Oliver Jowett 85d3ecee62 Add source & address type for Mode A/C 2016-10-11 17:55:02 +01:00
Oliver Jowett 52fe01c860 Track CPR encoding type directly rather than inferring it from airground. 
(airground can change even while airborne if SPI/Alert status gets set)
 2016-10-02 00:16:29 +01:00
Oliver Jowett 729d91c1ab Fix up address type categorization to match the spec. 2016-09-15 15:30:34 +01:00
Oliver Jowett 50a606d23f Make it clearer that ADDR_ADSB_ICAO includes Mode S too. 2016-09-14 17:19:49 +01:00
Oliver Jowett 8d8443f3dc Track the "best" addrtype we ever saw for an aircraft. 2016-09-14 16:54:00 +01:00
Oliver Jowett 2a4aa29f03 Record the address type details when decoding. 2016-09-14 16:37:07 +01:00
Oliver Jowett 3e08de91ed WIP on decoding operational status & target state messages. 2016-08-29 11:11:04 +01:00
Oliver Jowett 54ca2c7fb2 WIP big rewrite of message decoding / aircraft tracking. 2016-08-27 14:34:14 +01:00
Oliver Jowett 8b8f8d7a40 Use INVALID_ALTITUDE in a few more places. 2016-08-26 21:38:06 +01:00
Oliver Jowett e4ceea33da Disable the internal webserver at build time. 2016-07-10 11:56:31 +01:00
Oliver Jowett 8f82e61f17 Remove the 2MHz demodulator. 
Now that the 2.4MHz demodulator does 3A/C there's no real reason
to keep the old demodulator around.

Oliver Jowett b8dc3973d1 Always measure noise power, silently ignore --measure-noise if given. 2016-05-31 11:54:34 +01:00
Oliver Jowett d419b62a65 Always use phase enhancement; silently ignore --phase-enhance if given. 2016-05-31 11:47:57 +01:00
Oliver Jowett 93c135ea66 Remove a dead #define 2016-05-31 11:45:15 +01:00
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 d9eec668cf Track what data we got via TIS-B, report it as such. 2016-01-21 19:42:37 +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.
 2016-01-01 15:15:28 +00:00
Oliver Jowett efd6b94310 Track HAE altitude separately to baro altitude where possible. 2016-01-01 13:42:30 +00:00

Oliver Jowett 1c80d1b784 OS X compatibility cleanups. 
Reattach the licenses for the compat stuff to the source.
Only build/link the compat stuff when it's needed.
Rename compat/util.h so it's not confused with util.h.
Move all the platform specific defines inside compat/compat.h.

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 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.

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.
 2015-06-26 17:50:51 +01:00
Oliver Jowett 656df98a76 Add --stats-range 2015-06-19 17:29:14 +01:00
Oliver Jowett e7e9cecc1a Add --throttle option. 
This gives access to the existing throttling behaviour when reading
from a file with --interactive, without needing to actually have
--interactive.

This is useful when testing, as without --throttle samples will be
processsed much faster than real-time, which can produce different
results with e.g. aircraft/filter expiry times and position/speed checks.

Oliver Jowett 21bdc45bf0 Tweaks to noise measurements. 2015-06-16 10:13:25 +01:00
Oliver Jowett 03b53c2d29 Factor out the sample -> magnitude conversion code and make everything a little less sample-rate-dependent. 
Add optional noise measurement (cheaper than the old version)
Add optional DC filter (expensive, not really needed with rtlsdr input)
 2015-06-15 22:14:37 +01:00
Oliver Jowett 079de99eec Add --iformat option that controls the format of the data read from --ifile. 
This currently understands:

UC8 (original rtl_sdr format, 8-bit unsigned complex);
SC16 (16-bit signed complex, full width);
SC16Q11 (bladeRF native format: 16-bit signed complex with 11 bits of magnitude)
 2015-05-29 18:22:41 +01:00
Oliver Jowett 15ea5ba3da Rearrangements to the receive thread. 
Magnitude conversion now happens immediately when sample data is
received, so there is no risk of newly received data clobbering old
data under CPU overload.
 2015-04-09 18:51:31 +01:00
Oliver Jowett e1d262d992 Add --show-only for extracting messages from a single plane. 2015-02-22 23:01:54 +00:00
Oliver Jowett 8f3be2cd79 Decode aircraft category, export in aircraft.json. 
Closes #2.
 2015-02-22 12:15:26 +00:00
Oliver Jowett af382ac79c Fix max flush interval to be in milliseconds. 2015-02-10 23:43:48 +00:00
Oliver Jowett f9ed7e4a97 More time_t -> milliseconds conversions. 
This lets us support fractional net flush times among other things, which is handy.
 2015-02-10 22:24:22 +00:00
Oliver Jowett 7053ad02da Make aircraft tracking use milliseconds everywhere. 2015-02-10 21:49:37 +00:00
Oliver Jowett 9fd0c822f6 Extract NUCp from message type; needed for #16. 2015-02-09 14:14:12 +00:00
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,8,111,11111,392AEB,111111,2015/02/08,17:57:53.917,2015/02/08,17:57:53.936,,,,,,,,,,,,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.
