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

4d93b8f821 Collected all the local position stuff so it's specified once in uhd_modes.py.
Should probably add in a command-line parameter to specify this.

0bf5e47749 Various fixes for various exceptions.
You are seeing a couple of impossible altitudes and a couple of impossible longitudes. Looks like they're coming from the same aircraft. Possibly a nonstandard squitter? They pass checksum, but they don't contain the data you think they do.
