What ?
- RBS stand for Recovery Base Station
- Sat messenger is the satellite part of RBS
RBS
- There is a info website about this project
Sat Messenger
Hardware
- Satellite communication are based on Short Burst Message with a 9602 Modem
- All in one version can be found at rock7.com. We own a Rockblock +
Software
- rock7 documentation is sometimes wrong. i.e Serial communication use actually the standart 0D0A.
- makersnake library is a great start for the python way. Altough some URL has changed and some script are not complete. Most of our end user code is heavily based on the awesome works makersnake published.
Crypto
- Iridium SBD Messages are transmitted as is. So if you type clear text, it will be transmitted in... clear text. That's really sucks.
- In the RBS scenario there is no possible communication other than the sat messages and to have very short crypted messages we use some short stream cipher and hash function.
