gr-lilacsat


GNU Radio OOT Module for telemetry decoding of LilacSat-1, LilacSat-2 and BY70-1 satellites.

Tested on GRC 3.7.8 and 3.7.10.1, and ubuntu 14.04 LTS.

Currently this OOT module does not work on ubuntu 16.04 LTS. Please contact me if you can find a solution.

This project is supported by Harbin Institute of Technology.

frontend_rx_*.grc in examples folder for different devices:

  • frontend_rx_fcdpp.grc for Funcube Dongle Pro Plus (gr-fcdproplus needed);
  • frontend_rx_uhd.grc for USRP;
  • frontend_rx_rtl.grc for RTL-SDR.

demod_node*_*.grc in examples folder for different modulation and rate:

  • demod_node1_bpsk_9k6.grc for 437.200 MHz 9600 bps RRC-BPSK telemetry;
  • demod_node1_afsk.grc for 437.200 MHz 1200 bps AFSK-FM telemetry;
  • demod_node1_ccsds_fm.grc for 437.200 MHz 300 bps subaudio baseband telemetry;
  • demod_node4_4k8.grc for 437.225 MHz 4800 bps GFSK telemetry.
