NAME dump1090-mutability - Mode-S decoder

SYNOPSIS

       dump1090-mutability
       dump1090-mutability --interactive
       dump1090-mutability --ifile file

DESCRIPTION

       dump1090-mutability receives and decodes Mode S packets using the Realtek RTL2832 software
       defined radio interface.  It provides the ability to decode multiple frame types  as  well
       as  correct  bit errors using the embedded 24-bit CRC.  Results can be viewed using a text
       client, via the built- in HTTP server or forwarded off to other locations for collection.

       --snip level
              Strip IQ file removing samples  level

       --debug flags

       --quiet
              Disable output to stdout.

       --ppm error
              Set receiver error in parts per million (default 0)

       --help Show help

DIAGNOSTICS

       The Debug mode is a visual help to improve the detection algorithm or  to  understand  why
       the program is not working for a given input.

       In  this mode messages are displayed in an ASCII-art style graphical representation, where
       the individual magnitude bars sampled at 2MHz are displayed.

       An index shows the sample number, where 0 is the sample where the first Mode  S  peak  was
       found.  Some  additional  background  noise is also added before the first peak to provide
       some context.

       Select frames to log using the following flags:

       d      Log frames decoded with errors

       D      Log frames decoded with zero errors

       c      Log frames with bad CRC

       C      Log frames with good CRC

       p      Log frames with bad preamble

       n      Log network debugging info

       j      Log frames to frames.js, loadable by debug.html

EXAMPLES

       The most basic usage is with no flags, which will open the first found rtl-sdr device  and
       begin printing out hex dumps of the received packets.
              Most people will either run this in interactive mode or as a daemon.

       Interactive mode

               dump1090-mutability --interactive

       Daemon mode

               dump1090-mutability --net --quiet &

       You can also use dump1090-mutability as a network hub for multiple receivers by using

               dump1090-mutability --net-only
