No, each servo motor has two infrared sensors mounted on them. Each one of these assemblies is called a "tracker". You'll need at least two trackers, spaced as far apart as you can get them, before you can triangulate a heading and distance to the beacon(s). This is from the

Q: Got any photos of an example tracking assembly?
A: Glad you asked. Have a look here.
