a7e26c5960 mlat: fixed horrible bug in the solver. also noticed that [0,0,0] cannot contribute meaningful angular data, and so you still really want four stations on receive. there's still a bug in the solver somewhere that results in positions east of here not solving correctly. 2011-07-14 18:49:47 -07:00

f31e9e062f Added SBS support for aircraft and flight ID 
Looking at the SBS output, flight ID is just aircraft ID +
100. Aircraft ID is just a unique count to make parsing the output
file easier.

I'm not sure how useful this is but it makes us a step closer towards
mimicking the SBS.

I also pull out the ID for squitters 0, 4, and 5.

4220255908 Added comments and change surface reports to MSG2 
2 important things happened here:

-> Surface position reports where changed from MSG3 to MSG2. I believe
   this is what that SBS message means.
-> MEs 1-4 are aircraft identification packets. Those should go to SBS
   MSG1.

7f9574b7cd Added missing MSGs 5,6,7,8 for SBS output 
These are the 56 bit ADS-B message about altitude and such. Not as
cool as the the extended messages but still useful non the less.

1bbd29d09c Correct mode_sbs1 so that it runs 
Msg return output has changed. Time is now only a single variable.

16c94988e6 Remove uneeded include 
I don't believe this is required anymore as everything here uses UHD.

c3dacc667e Allow the user to set which antenna to use on the sub device 
So .. from the terminal, "-A RX2", would set the device to use the RX2
antenna.The UHD manual will define your options. If the user puts in a
bad selection, it will complain and list the options.

72acc5e3c1 Default int & dump to "no", use center sampling instead. 
A learning experience I guess. If the pulse isn't REALLY square,
and instead is bandlimited in any way, integrate & dump doesn't work
as well as center sampling.

At any rate, the completely rewritten decoder should be both faster
and more sensitive than before.

8b1c1791c7 Everything changed. 
* Rewrote preamble detector. Uses integrate-and-dump along with correlator to perform optimal receive.
* No longer using framer. Determining packet length via header. Missing some anti-FRUIT stuff.
* Pulled out the slicer logic into its own function.

Lots of todos and fixmes.

f8966f0d10 All tags, all the time. Still some weirdness with set_history() that requires using the check widths in the framer & slicer. 2010-11-20 17:06:48 -08:00

cd394e1863 Preamble now passes tags to framer. 
Note: Using set_history cocks up the nitems_written() call.
