DragonOS is a ready to use Linux OS image that includes many SDR programs preinstalled and ready to use. The creator Aaron also runs a YouTube channel that has multiple tutorial videos demonstrating software built into DragonOS.
In a recent video Aaron shows how you can set up a GSM basestation within minutes by using the latest DragonOS version together with a USRP b205mini-i software defined radio. As the required software (osmo-BTS, osmo-bts, osmo-bts-trx) is all preinstalled, setting up the basestation is a simple matter of opening three terminal windows and running a few commands. We note that this latest DragonOS version is due to be released this Thursday.
In a previous video Aaron also shows a more detailed setup procedure showing how all the software was installed.
