Official Simulator
FiraSIM
Based on gr-sim simulator, receive data from simulator is similar to receiving data from SSL-Vision using Google Protobuf library.
Sending data to the simulator is also possible using Google Protobuf. Sample clients are included in clients folder.
There are two clients available, qt-based and Java-based. The native client is compiled during the normal compilation.
The simulator compiles on Linux and MacOS. Simulador will run on dual core PC with 1GB of RAM and a simple graphic card.
