-This component implements an NOAA POES HRPT receiver. After installation,
-the scripts described below will be install in the users PATH.
-
-As the scripts are generated using GRC, GRC must be installed at runtime
-in order for them to operate.
-
-
-HRPT OPERATION
-
-usrp_rx_hrpt.py
----------------
-
-This GUI script will receive HRPT RF, demodulate, synchronize, and deframe
-HRPT minor frames into a file. The file stores a series of 11090 word,
-16-bits per word corresponding to the HRPT minor frame format (only the
-lower 10-bits per word are significant.)
-
-The script file by default uses USRP side A, 1698 MHz, at decimation 16. The
-gnuradio configuration file ~/.gnuradio/config.conf, section 'usrp_rx_hrpt.cfg',
-will allow changing this, as well as implementing persistent storage of GUI
-entered parameters from invocation to invocation.
-
-The present HRPT demodulator is only tested at decimation 16. The only other
-valid decimation rates are 24 and 32, which may work but with more bit
-errors. No other decimation rates will work.
-
-
-file_rx_hrpt.py
----------------
-
-This GUI script operates like usrp_rx_hrpt.py, but reads from a pre-captured
-data file supplied by -F on the command line.
-
-
-usrp_rx_hrpt_nogui.py
----------------------
-
-This non-GUI script operates without a display and requires that all parameters
-be set in the configuration file prior to running. It has no command-line
-parameters, and works identically to the GUI scripts.
-
-
-hrpt_demod_file.py
-------------------
-
-This non-GUI script will operate on a file generated with
-usrp_rx_cfile.py and output frames in the same format as above. It does
-*not* use the configuration file above; instead you must pass parameters to
-it on the command line. To exit the program, press Enter.
-
-Usage: demod_hrpt_file.py: [options]
-
-Options:
- -h, --help show this help message and exit
- -d DECIM, --decim=DECIM
- Set Decimation [default=16]
- -p PLL_ALPHA, --pll-alpha=PLL_ALPHA
- Set pll_alpha [default=50m]
- -s CLOCK_ALPHA, --clock-alpha=CLOCK_ALPHA
- Set clock_alpha [default=50m]
- -F INPUT_FILENAME, --input-filename=INPUT_FILENAME
- Set Filename [default=usrp.dat]
- -o OUTPUT_FILENAME, --output-filename=OUTPUT_FILENAME
- Set Output [default=frames.dat]
-

-LRIT Operation
---------------
-
-The work-in-progress LRIT GRC script is not currently in a usable state.
