Iridium

Postby dannyllama » Tue Jun 14, 2016 9:38 am

Hi all. I bought the SDRPlay primarily for L-Band decoding (Inmarsat & Iridium). With Inmarsat I am having good success, but with Iridium I have not been able to proceed. I cannot see how it's possible to run the MUCCC Iridium decoding software with the SDRPlay. With RTl or HackRF it's no issue.

Does anyone have experience in decoding Iridium with SDRPlay?

hi danny,

it works by using the play_sdr in the github repository of sdrplay.... hopefully the new api will be released soon with the promised AGC then i hope it will do alot better.....

Iridium, I use to monitor Inmarsat using a homebrew helical, a TV dish (BUD) and a Yupi MVT-7100. Are there any voice comms on there anymore?

Thanks
JC

Sure, there are a lot of voice comms on there still...but it's all digital

This is great news. Can you please provide me with the command line that you use to make it work with play_sdr?

I am stuck on what the command line should be to get the Iridium decoder and RSP working on Linux. I am receiving Inmarsat currently, so it's just the command line that's stopping me. So close yet so far :(
