Low Earth Orbiting Satellites – Opportunities and Challenges

Low-Earth orbiting (LEO) satellites are now providing broadband service to users around the world. But they face space congestion problems. Some satellites must steer around each other to avoid collisions. In addition, the LEO satellites must share radio spectrum with geosynchronous Earth-orbiting (GEO) satellites and, more interestingly, with each <a href="http://other.

This presentation will touch on collision avoidance but will focus on beam steering and other ways that these satellites can efficiently share spectrum with each other. There are a variety of ways they can do this. Some require information sharing, but others do not. Our work at Carnegie Mellon is examining the effectiveness of various spectrum sharing <a href="http://methods.
