DESCRIPTION Two helical-type slaved rotating antennas (completed in 1963) are
available for tracking free flight rockets. These antennas are mounted on 12-ft.
high steel towers atop the Command and Tracking Center (Building 660). The
towers are designed so that deflection or rotation from a 30 knot wind will cause
less than 0.1 degree error in tracking. The tracking rate on any axis is 20 degree per second with an acceleration of 5 degrees per second. Signal cables run
from the Command and Tracking Center to each antenna.
