Portscanning Low Earth Orbit

by Travis Goodspeed

Satellites are orbiting all around our little planet, but the lack of tools for accessing them have limited past research to stationary satellites or to ones with documented communications protocols. This lecture will teach you how to take an old telecom dish from a Navy ship, rewire it for computer control, and then target moving satellites. All targeting is performed by a collection of Unix daemons, and all reception is performed by a flexible software defined radio.
