Abstract : Contract effort can be grouped under programs concerned with telemetry system studies, rocket and balloon instrumentation systems, orbiting vehicles, field support for certain sounding rockets and balloons, and evaluation of commercial telemetry system components. The telemetry system studies are concerned with signal-to-noise improvement in frequency division multiplex systems and deal with subcarrier pre-emphasis tapers, computer analysis of FM/FM spectrums and extension of system threshold. The orbital vehicle effort is concerned with the solar panels and a magnetic tape recorder for the Cannonball II satellite as well as the solar power analysis of an additional vehicle. The field support rendered in connection with the various programs is tabulated. (Author)
