Background: The IGOR camera that tracks the Apollo after liftoff is located on a beach at Patrick Air Force base, 25 miles south of the launch pad at Merritt Island.
It's a large telescope system mounted inside an igloo-shaped astrodome, with the capability of swiveling around to any point on the compass.
The name "IGOR" is a brief form for Intercept Ground Optical Recorded - which means it can take long-range photographs of objects in space.
The station is manned by three men, who have constant reference on a television screen while they are filming the spacecraft in flight at the same time.
By checking the T-V displays the crew can coordinate their telescope-aiming with the radar system that locks onto the target.
A man in the control room also feeds the television picture to the range control center at Cape Kennedy, as well as to Houston.
Two men cooperate the camera itself with hand-wheels - one controlling azimuth (or direction of flight), the other maintaining the same elevation as the target.
Long-range cameras like the IGOR have been operating for manned and unmanned flights since the early days of the space program. The IGOR itself has been used since Gemini.
