Pulse-Time Modulation Telemetering Systems for Rocket Application

The Naval Research Laboratory has designed and operated two long-range multichannel pulse-time modulation telemetering systems for over 55 V-2 and Viking rocket firings at the White Sands Proving Grounds. Design and operational data are given for a 23-channel, 1-kw peak pulse power system and for an improved 30-channel, 4-kw peak pulse power system, together with photographs of the equipment and sample records obtained.
