Data Transmission and Instrumentation Systems for Space Vehicles

摘要

The report summarizes the main work carried out under this contract (April 1, 1963 through March 31, 1967). The contract effort can be grouped under programs concerned with an orbiting vehicle, a re-entry vehicle, field support for certain sounding rockets and balloons, evaluation of commercial telemetry system components, and system studies and developments related to telemetry and weather radar. The orbital vehicle effort is concerned with a telemetry subsystem, a data storage system, aspect instrumentation and determination and a commutator. The discussion of the instrumentation of a Trailblazer II rocket for a re-entry experiment includes treatment of an s-band pulsed system, an x-band PPM telemeter and certain probes. A tabulation is given of commercial airborne telemetry components tested and evaluated since detailed results are published in scientific reports which are available to authorized agencies. The field support rendered in connection with the various programs is tabulated. Specific discussion is given to a PAM/FM system, temperature studies of balloon telemetry systems, and the modification of a weather radar. (Author)
