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

For on GRC 3.8.x. For 3.7.x please use the maint-3.7 branch.

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.

Requirements

---

• gr-csp
• construct 2.8 For telemetry parser
• feh For realtime image display

Examples

---

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.

Use frontend_rx_*.grc, demod_node1_bpsk_9k6.grc and demod_node4_4k8.grc by default.

proxy_publish is also included in examples folder for upload telemetry for display.
