IR Seeker Drone

Is it possible to have a drone that can fly to an IR beacon?

Have looked around a bit, but didn't find anything useful. My idea is to put an ir phototransistor on the drone and then have it actively seek out an IR beacon.

Yes. Perhaps this article will provide some useful hints: http://diydrones.com/profiles/blogs/infrared-beacon-guidance-for-the-arducopter A Google search for infrared beacon tracking will turn up more.
