TELEMETERING PICKUPS,
Abstract
Pickups were designed and constructed to measure a wide variety of physical quantities for transmission from test vehicles to ground stations. These designs have been subject to the rigid requirements and configurations of flight-test vehicles, the important requisites being ruggedness, compactness, and accuracy. The physical quantities measured include pressure, acceleration, temperature, orientation, force, and velocity. Most of the pickup instruments are of the variable inductance type, in which a physical change effects a variation in inductance and, consequently, a corresponding frequency change in a subcarrier oscillator. The important constructional features of the inductance units and the various types of pickups are described and calibration techniques and performance characteristics are discussed. Also included are proposals for future modifications and improvements. (Author)
