This document discusses satellite hacking for fun and profit. It describes how the speaker analyzes unencrypted satellite feeds using affordable open source software and hardware like Dreambox satellite receivers. Visualization tools are created to make satellite hacking easier, such as a 3D model that allows pointing a satellite dish and decoding streams directly within the model interface. The speaker advocates exploring open standards and avoiding proprietary systems to analyze satellite streams.
