Instrumentation for balloon and rocket experiments.

Description of a number of plasma, particle, and field detectors used on rocket investigations in and above the earth's atmosphere. Emphasis is on magnetospheric and solar-interplanetary studies. A balloon-borne X-ray telescope system with 20-min pointing accuracy is discussed. A PCM telemetry system used on both balloons and rockets to handle scientific data is described which includes a simple Doppler ranging system that gives location to 1.5 km. A system to reduce and analyze PCM data on the ground is discussed.
