David Stipp ae126d1009 Add back Darwin/Mach/Apple portability 
Quite a few of the changes against the MalcolmRobb/dump1090 fork are
incompatible with OSX.  This patch adds back that cross platform support
back.

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 5fa039a2d4 Only require librtlsdr headers while we're compiling dump1090, 
not the other helpers that don't use the dongle.

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 ff094519a6 Fix interactive-mode delay timing when using --ifile. 2015-04-09 19:18:49 +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 e6c81251bf Fix timestamp correction when sample blocks are dropped. 
(Fixes #43)
 2015-04-08 19:13:40 +01:00

Oliver Jowett 38845c2447 Rearrange main loop so that --net-only isn't quite such a special case. 2015-02-17 21:44:30 +00:00
Oliver Jowett 0a055c34d0 Log timestamped messages on startup/shutdown. 2015-02-17 21:43:17 +00:00
Oliver Jowett dcdfd2acab Catch SIGTERM, log on signals. 
Fixes #22.
 2015-02-17 21:41:40 +00:00
Oliver Jowett 342eafd438 Include timestamps on USB connect/disconnect logging. 
Fixes #21.
 2015-02-17 21:40:26 +00:00
Oliver Jowett 03e096475c Wait for at most 100ms for more data from the rx thread, so that we do not starve background tasks if the rx thread blocks (e.g on USB disconnect). 
Fixes #20.
 2015-02-17 21:07:36 +00:00
Oliver Jowett 7849e1019d Init start/end on all stats so the json output looks sensible for the first minute. 2015-02-11 01:14:21 +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 bdefa42956 Merge pull request #11 from jburgess777/add-oversample-to-help 
Add --oversample option to help text
 2015-02-08 18:07:23 +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.
 2015-02-08 17:46:01 +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 9deac8d894 Continuing to try to work around libusb/librtlsdr problems. 2015-01-23 01:20:22 +00:00
Oliver Jowett 008ae926e7 Add --net-verbatim, which forwards the original uncorrected message to net clients, 
not the corrected version. Then the client can make its own policy decisions about
whether to accept and correct the damaged messages.
