36.9 Megahertz Helix Antenna
Doppler Velocity and Position (DOVAP)
Reference Transmitter Antenna
DOVAP measures a rocketís position in space using the
Doppler effect caused by a target moving relative to a ground transmitter and
Developed during World War II by the Germans as part of
a V-2 ground guidance and control system, at White Sands the DOVAP system
provided trajectory data and ground guidance for most of the early rocket
systems: Corporal, Sergeant, Honest John, Little John, Redstone, and Aerobee
Upper Atmosphere programs.
Like much of the early instrumentation, it was designed
and built at White Sands Missile Range. This particular antenna was built in the
mid-1960s near C Station.
