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 -h, --help show the help message and exit --version show program's version number and exit --list_satellites list supported satellites and exit Input options --wavfile WAVFILE WAV/OGG/FLAC input file (using libsndfile) --rawfile RAWFILE RAW input file (float32 or complex64) --rawint16 RAWINT16 RAW input file (int16) --audio [DEVICE] Soundcard device input --udp Use UDP input --kiss_in KISS_IN KISS input file --samp_rate SAMP_RATE Sample rate (Hz) --udp_ip UDP_IP UDP input listen IP [default='::'] --udp_port UDP_PORT UDP input listen port [default='7355'] --iq Use IQ input --input_gain INPUT_GAIN Input gain (can be negative to invert signal) [default=1] --start_time START_TIME Recording start timestamp --throttle Throttle recording input to 1x speed Output options --kiss_out KISS_OUT KISS output file --kiss_append Append to KISS output file --kiss_server [PORT] Enable KISS server [default port=8100] --kiss_server_address KISS_SERVER_ADDRESS KISS server bind address [default='127.0.0.1'] --zmq_pub [ADDRESS] Enable ZMQ PUB socket [default address=tcp://127.0.0.1:5555] --hexdump Hexdump instead of telemetry parse --dump_path DUMP_PATH Path to dump internal signals Demodulation options --f_offset F_OFFSET Frequency offset (Hz) [default=1500 or 12000] --rrc_alpha RRC_ALPHA RRC roll-off (Hz) [default=0.35] --disable_fll Disable FLL --fll_bw FLL_BW FLL bandwidth (Hz) [default=25] --clk_bw CLK_BW Clock recovery bandwidth (relative to baudrate) [default=0.06] --clk_limit CLK_LIMIT Clock recovery limit (relative to baudrate) [default=0.02] --costas_bw COSTAS_BW Costas loop bandwidth (Hz) [default=50] --manchester_history MANCHESTER_HISTORY Manchester recovery history (symbols) [default=32] Deframing options --syncword_threshold SYNCWORD_THRESHOLD Syncword bit errors [default=8] --verbose_rs Verbose RS decoder Data sink --telemetry_output TELEMETRY_OUTPUT Telemetry output file [default=stdout]
