Abstract :
A new 15-pound mechanically commutated telemetering system developed by the General Electric Company and designed for use with rockets speeding at 3,800 miles per hour recently was tested successfully at the United States Army Ordnance Proving Ground, White Sands, N. Mex. The system uses only ten electronic tubes and is packaged in two pressurized cans, each four inches in diameter and 12 and 15 inches long. Power is supplied by a separate 28-volt battery, located in the control compartment, which weighs 12 pounds. Every 1/35 of a second 28 items are sent by the 5-watt transmitter in the rocket and are received at the ground station where they are recorded permanently on film from one cathode ray oscilloscope.
