A "reliable" message is a DF17 or DF11 with good CRC.
A "reliable" aircraft is one that's probably real - we decide it's reliable when
we've seen enough reliable messages, or just enough messages in total, that it's unlikely
to be noise.
Check the return value from accept_data to determine if we want to
use the decoded position.
Avoid a position from local CPR with a synthetic MLAT message being used
when the position may still be valid and either odd or even CPR already
stale allowing the MLAT CPR to be used.
Set the position expiration correctly for global surface CPR, the
previous code could have an up to 50 second old CPR being used, which
would result in combine_validity setting an expiry time for the position
only 10 seconds in the future.
In addition to the usual updated data, this update fixes a number
of ICAO type designator errors in the FlightAware static data
export (notably for the A330).
Fixes#17
registrations.js would miscalculate the end of the address range
in these cases, causing the mapping to be skipped for addresses
that we could have handled.
This specifically affected German registrations beginning with
D-AP through D-AZ and D-BP through D-BZ
rather than blanking them out entirely.
This lets csv-to-json.py handle the case where an earlier input file has (e.g.)
a registration value which does not match the computed value, and then a later
input file has a value that does match. In this case we want to override the
older value with the newer value, then notice that the registration can be
omitted when writing the database. Previously in this case the older (incorrect)
value would be used.
When determining the color for a given altitude, don't check the current
altitude if it's ground but the altitude passed as an argument to the
function.
Without this fix, when clicking an aircraft on ground, its entire trail
is drawn in the color for ground.
When loading the history, the check for stale aircraft tracks is done
differently.
This results in lots of dotted/stale track after opening the web page.
Improve this by using the same 5 second timeout stale criterion to
postions loaded from history. Add an additional check to better detect
stale tracks when loading history positions that are spaced 30 seconds
apart.
Make aircraft trail handling more consistent and the code hopefully
easier to understand.
Fix position comparison (comparing array references does not work).
When initially loading the SkyView webpage, there are sometimes gaps in
the aircraft trails when the trail transitions from estimated/dotted to
known/solid track.
Fix elastic band style to handle estimated segments properly.
Right now all of these commands are in plaintext in a single line. Splitting them in a code block makes it more readable and easier to copy and paste directly into a terminal.
