Boresight range tower is (or has been in the past a tower on which the radar transponder for a target vehicle is mounted The capsule then communicates with the transponder. Feel sure that here the GT-8 capsule (which will dock with an Agena) will use the Agena 5003 on the radar boresight tower in tests of the radar transponder system. The system perm is the spacecraft to "talk" to the object it is trying to rendezvous with -- saying "where are you" and the target answering "here I am." This is done by sending radar pulses from the spacecraft which are received by the transponder on the target, amplified, and sent back to the spacecraft. In the spacecraft, a computer uses the shift in frequency of the returned signals to figure out where the target is in relation to the spacecraft and give instructions of ??? to close the gap.
Hoe that's what this is all about, ???
