Iridium Satellite Decoding Part 1: The Tutorial That Goes Over Your Head, Literally!
HTML-код
- Опубликовано: 12 сен 2024
- Recently I experienced an influx of emails in my inbox requesting help with Iridium decoding. So, I thought I would throw together a one or two part series on how to get started with receiving L-band signals from Iridium satellites using relatively cheap hardware and a couple of free software tools for Linux.
What is Iridium exactly? Before there was Starlink, there was Iridium! It is a low earth orbiting constellation of communication satellites providing voice and data services to the surface of the Earth. Typical applications of the Iridium network are satellite phones and internet connectivity for aircraft and marine vessels.
Join me in part one today, where I outline the hardware and software requirements for decoding Iridium and demonstrate the usage of the 'gr-iridium' software which is used for the actual capturing and recording phase of the decoding process.
In the upcoming part two video, I will be demonstrating the usage of 'Iridium-toolkit' and how it can be utilized to extract useful data from recordings of Iridium satellite data.
Thanks for watching!

I finally got a notification! Thanks for going over this in far more detail. You had me laughing in the beginning. It’s refreshing to listen to things like this being fully explained.
@cemaxecuter7783 Thanks for the repost on Twitter, you're the best! 😁Obviously you're heard about the 'QCSuper' project? Any plans in the pipeline to get that working in DragonOS FocalX? Thanks for watching mate!
@@RobVK8FOES I did briefly test and include QCsuper and then removed it and then recently added it back. It’s sitting in /usr/src on the latest ISO. I’ll have to go check what model, but I bought a OnePlus something just to give it a go.
You’re on rtlsdr blog! So here’s my 2025 resolutions early.. show my face on videos, get an accent like you, and share more details! Haha I’m a peasant now at 13k followers compared to you 🤣
@cemaxecuter7783 For the record, I think it's an absolute travesty that I somehow have more subscribers than you. I always do my best to give you exposure in my videos, since everything I do on my channel wouldn't be possible without the great Cemaxecuter!
@@RobVK8FOES I greatly appreciate it! I think it’s great though you have a big audience, you’re doing an amazing job of explaining things and using it. I still think a joint video would be great to, although I never did get the gsm / asterisk / online sip provider going. I had high hopes of one I found, but ultimately it didn’t work. I think I need to dig back into asterisk. But maybe we could cheat and do LTE both ends and use an IP based app to talk haha
excellent video! keep up the good work.
Hey, great video! I am a Student and I'd like to know where you get this knowledge? can you recommend a good book, paper or youtube channel? greetings from TU Munich
Hi @Ibrahim-rc8sn, I am a 100% self-taught tinkerer and experimenter. If you send me an email to vk8foes@gmail.com and I will point you in the right direction.
@@RobVK8FOES OK I wrote u an email!
Looking forward to part2👍
Awesome thanks really easy to follow along 👍
2:18 What this about 'Australia' and 'sparse population'?
In case theirs any foreigners here hes actually joking guys. We're completely full.
Lol!
thank you. Very interesting and well presented.
Is there any sattlites that you legally intercept signals such as a weather sattlite?
Hi. And yes, there is a number of weather satellites whos signals can be decoded. It's dependent on your location, we have no weather satellites to decode here in the eastern hemisphere (to my knowledge, anyway) Eumetsat and GOES are two examples
Thanks for this video❤
Wow.. Awesome..
Thank you!
Hi sir... can u see any information about the SUN ACTIVITIE in satelites?
Have you played with active data sending?
I own an Iridium 9505 satellite phone, I have made and received a few calls with it, if that counts?
@@RobVK8FOES As long as you don't have a plan... :)
Awesome
Thanks for watching!
Rob can we also know the number calling from data captured ?
@bobyyansyah5204 Yes, it is possible. You have to export the GSM layer 3 messages as PCAP format and open it with Wireshark to locate the call setup packets. I think the field is called "Calling Party BCD Number"
what was the current time? 17 years ago? ;p
(ahh, the network. not the chem)
aw what, you drink furphy? spose, it could be worse.
Carlton Dry, mothers milk mate 😄
@@RobVK8FOES alright unsubbed now.. lel
@alch3myau Let me guess, you drink Swan? Or even worse, bush chook!
@@RobVK8FOES fk no. Monsuta
@@RobVK8FOES hm last post aint showing? .. Nah Monsuta
