Previously it forgot to advance to the next aircraft and only
happened to work because it cleared the position bitflags and so
the next iteration (on the same aircraft) would advance.
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)
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.
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.
* use PageName, not literal "DUMP1090"
* use document.title directly, not a selector
* include number of positionless aircraft too
* rename the config options
* some simplification of the changes
This would mangle messages if the first byte of a message ended up
as the last byte returned by a read() call - it would read beyond
the end of the buffer, decide the message was damaged, and then run
off into the message data looking for a new delimiter. Sometimes
that would work (only dropping one message), but sometimes it would
run into data that happened to look like a message start but
actually wasn't, and then try to interpret that, leading to completely
bogus message data being read.
Fixes#29.
Added some code to enable the user to configure unit selection in a more
detailed fashion. you can now select either metric or imperial, or both,
and even set which one of those should be displayed first.
* check the username fits the format expected by adduser;
* don't allow root;
* if the user exists, don't try to create it; usually, this is
harmless, but it fails if the user exists with a UID outside the
normal range for system users.
Fixes#24.
Track NUCp when we compute positions.
Do speed checks when we have an updated position with the same or worse NUCp
before accepting the new position. Don't do speed checks on new postions if
they improve NUCp - assume that the new position is better.
Include NUCp in aircraft.json
Gather stats on reasons for rejecting CPR data due to range/speed check failures.
Expire old positions if we have had no updates for 60 seconds.
Closes#16, closes#17.
