|| ||
|| == INTRO == ||
|| ||
|| Let’s get with the times and do some 25th century space phreaking and ||
|| learn how to decode Iridium sat phones! :3 ||
|| ||
|| This is going to be one of those “Noir” write-ups so please understand ||
|| what I’m about to explain may be unlawful. Please treat this document as ||
|| an educational/entertainment piece and make good decisions with this ||
|| knowledge. The disclaimer below outlines what laws may apply to decoding ||
|| Iridium communications so please read through it. ||
|| ||
|| Any who, I hope you get to learn something fun here and happy hacking! :D ||
|| ||
|| ||
|| == Disclaimer == ||
|| ||
|| Some of the practices and methods described in write up may be illegal ||
|| in your area. Even though Iridium transmits in plain text it still may ||
|| be considered a crime to record and decode. Please use your better ||
|| judgment while playing with this tech. If you live in the US please ||
|| review the “Wiretap Act” before continuing. ||
|| ||

|| == IRIDIUM == ||
|| ||
|| With out getting too far into the weeds about how Iridium works here’s a ||
|| quick summery on it’s characteristics… ||
|| ||
|| -> Security: Iridium doesn't make use of encryption within ||
|| the spec so data in transit is plain text. Encryption can be ||
|| implemented by venders however it’s used outside of the spec. ||
|| -> Freq Range: 1.6160GHz -> 1.6265GHz ||
|| -> Channels: 240 in total, 31.5KHz Bandwidth, 41.667KHz Spacing ||
|| -> Modulation: DEQPSK ||
|| -> Symbol Rate: 25k ||
|| -> Voice: AMBE vocoder by Digital Voice System Inc. ||
|| -> Each Sat covers a 4500km^2 area ||
|| -> Each Sat has 48 spot beams for focused links ||
|| (covers 400km^2 per beam) ||
|| ||
|| 12 Frequency access bands reserved for simplex ring alert and messaging ||
|| channels ||

|| ||
|| == HARDWARE == ||
|| ||
|| Below is the hardware I used to successfully capture Iridium packets. ||
|| ||
|| -> RPI 4 ||
|| -> Nooelec NESDR SMArTee (RTL2832U with TXCO and an “always-on” ||
|| Bias Tee) ||
|| -> Nuand BT-200 LNA (Low Noise Amplifier) ||
|| -> 1.6GHz QFH Antenna (Custom, also has a bunny ear ground plane! :D) ||
|| ||
|| Image: Receiver Setup ||
|| ||
|| If you want to save money with the antenna and LNA, you can hack a $10 ||
|| active GPS antenna by removing the filter and bridging the transmission ||
|| line (Or replacing it with an L-Band filter). The image below is an ||
|| example of a hacked GPS antenna. ||
|| ||
|| Image: Hacked GPS Antenna ||
|| ||
|| Just a heads up but your mileage may very. Because these active antennas ||
|| are built cheaply they may fail right after you mod it. For your reference ||
|| the image bellow shows what a bad active antenna looks like in a FFT with ||
|| the Bias Tee on. ||
|| ||
|| Image: Bad Antenna ||
|| ||
|| ||
|| == SOFTWARE == ||
|| ||
|| As mentioned above I’m using a Rpi 4 with the latest RPi OS Lite build. ||
|| The apt packages below are what I used to get the RTL-SDR and the ||
|| gr-iridium software to work. This is RPi OS specific however there may be ||
|| some carry over with what’s below if you’re using another Debian flavored ||
|| Linux (Ubuntu, Kali, etc). ||

|| ||
|| To decode the packets captured by gr-iridium you’ll need Iridium Toolkit ||
|| and the AMBE decoder if you want to decode voice. You have two options for ||
|| the AMBE decoder, you can either install the open source version ||
|| (osmo-ir77) or rip the codec from commercial firmware. I’ve had more ||
|| success with ripping the codec, however I’ll go over both processes. ||
|| ||
|| First lets download the Iridium Toolkit ||

|| == CONCLUSION == ||
|| ||
|| This was just a quick and dirty example on how you can surf the waves of ||
|| SIN by poking around Iridium! :D ||
|| ||
|| I encourage you to read up on Iridium and to review the source code to ||
|| see how this all works. I would also like to thank the MUCCC for ||
|| maintaining this code and making this possible for us to explore satellite ||
|| communications! ||
|| ||
|| Until we meet again, happy hacking! ||
