'''
This is the GNU Radio gr-air-modes package. It provides a library and
application for receiving Mode S / ADS-B signals from aircraft. Use
uhd_modes.py as the main application for receiving signals. cpr.py
provides an implementation of Compact Position Reporting. altitude.py
implements Gray-coded altitude decoding. Various plugins exist for SQL,
KML, and PlanePlotter-compliant SBS-1 emulation output. mlat.py provides
an experimental implementation of a multilateration solver.
