Category: Telemetry

BLUEWALKER-3 telemetry over Sollentuna/Stockholm. Very strong at 437.500 MHz but only one decode with SoundModem. It could/should be more.

#Celesta received over Stockholm 2022-07-26 and one packet uploaded to #satnogs

Used hardware and software:

• RX at 436.500 MHz Wide FM BW 8 kHz
• 2 x 13 el LFA X-Yagi (InnovAntenna) horisontal polarization worked best
• AlfaSpid RAS az/el rotor
• LNA Mini-70 from SHF Elektronik
• LMR-400 coax
• Airspy Mini SDR
• SDR-Console v3 with doppler correction of downlink and satellite tracking, rotor control
• PstRotator for rotor control interface between SDR-Console and RAS controller
• VB-Cable: virtual audio cable for piping audio from SDR Console to Soundmodem. Set to 96 kHz and 16 bit.
• HS Soundmodem version INS-2TD v0.01b at 2400bd
• GetKISS+ v 1.3.13 from DK3WN

#greencube received over Stockholm 2022-07-24 with 1KUNS-PF decoder at 2k4.

• Use Wide-FM during receive
• Note that the baudrate can change at any time
• More information see: https://www.s5lab.space/index.php/greencube-tracking/

And look at this amazing MEO orbit!

The use of Dual Channel in SoundModem make it easy to watch and decode two different baudrates in same pass.

Nothing heard from AO-27 2022-06-15 08:45 UTC north pass

Strong signal and many packets decoded and uploaded to @satnogs dB.
