Summary — Methods of obtaining ballistic data on long-range and guided missiles in the Army Ordnance Department's missile program at White Sands Proving Ground are described. The use of motion pictures for obtaining trajectory measurements and information on detailed flight performance of missiles launched at the White Sands range has produced a significant wealth of data for use of ballisticians and design engineers engaged in the development of long-range guided missiles.
I HE USE OF MOTION PICTURES as a method of obtaining ballistic data on full-scale, free-flight missiles and guided missiles has employed at the White Sands Proving Ground, New Mexico, since the summer of 1945. At that station, where the Army Ordnance Department, in collaboration with other departments of the Armed Services, conducts flight tests of high-altitude and long-range missiles, the Ballistic Research Laboratories have installed and operate several types of motion picture instruments by means of which a variety of experimental work is carried out in connection with the missile program.
Theoretical and experimental work on the development of observing methods and instrumentation is performed by the Ballistic Research Laboratories at Aberdeen Proving Ground. These methods and instruments are applied at the White Sands range for the purpose of obtaining basic data to be used by design engineers in the development of new weapons.
Other methods of obtaining ballistic data are used also since observing conditions, the different types of data required, accuracy requirements, time limits to be met, and the cost of the entire missile project make it impractical to depend upon a single method. Both groundand missile-borne instruments of electronic as well as optical types
