NAME

       gr_satellites  -  gr-satellites  is  a  GNU  Radio  command  line  decoder  for  the telemetry of Amateur
       satellites.

SYNOPSIS

       gr_satellites satellite [options]

DESCRIPTION

       gr-satellites is a GNU Radio out-of-tree module encompassing a  collection  of  telemetry  decoders  that
       supports  many  different  Amateur  satellites.  It  supports  most popular protocols, such as AX.25, the
       GOMspace NanoCom U482C and AX100 modems, an important part of the CCSDS stack, the AO-40 protocol used in
       the FUNcube satellites, and several ad-hoc protocols used in other satellites.

       The gr_satellites command line tool can be used to decode frames from each of the supported satellites by
       using either real-time RF samples from an SDR or conventional radio, or a recording.

OPTIONS

       The satellite parameter can be specified using name, NORAD ID or path to YAML file. The set of  available
       options  will  change depending on the satellite, so it is mandatory to specify a satellite even to print
       the full help.

       The options shown below are for the satellite AO-73. Other satellites have slightly different options.

   General options
