  • Astronomy for the Non-Astronomer

    Kinematical observations of the solar system have attained an accuracy reached in few other areas of measurement. The adequate description of these observations requires an elaborate and accurate terminology. This paper defines and discusses most of the important terms, coordinate systems, and methods of time reckoning which are used by astronomers in describing the motion of the solar system. No previous background in astronomy on the part of the reader is required. Warning is also given concerning terms whose meanings look obvious, but which in fact do not mean what they seem to.

  • Energy Spectra of FM System with Low Beta, High Deviation Ratio, and MF Which Approaches Carrier Frequency

    Publication Year: 1960 , Page(s): 17 - 19

    A technique was developed at the Naval Air Missile Test Center to determine energy spectra of an FM system which has a low Beta, a high deviation ratio, and a modulation frequency which approaches the carrier frequency. Ths technique may be used for analysis of any FM wave and yields theoretical results which conform closely to actual operating results. View full abstract»

  • How Environment Affects Magnetic Recording Tape

    Publication Year: 1960 , Page(s): 19 - 24
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (3656 KB)  

    The increasing emphasis on higher and higher operating and/or storage temperatures for data acquisition apparatus requires a critical appraisal of the behavior of available magnetic recording tapes as their rated operating limits are approached or exceeded. Among the criteria that bear examination are the dimensional stability, strength and toughness of the substrate, and the chemical stability of the binder and the magnetic material. Unexpected physical effects can be experienced within the generally accepted ``safe'' environmental limits. Critical temperatures and observed effects are described. View full abstract»

  • Threshold Improvement in an FM Subcarrier System

    Publication Year: 1960 , Page(s): 25 - 33
    Cited by:  Papers (5)

    The paper is concerned with the causes and characteristics of threshold behavior in pulse-averaging and phase-coherent (``phase-locked loop'') FM subcarrier discriminators. An analytical discussion of the basic elements of each form of discriminator is first presented, leading to a comparison of the devices for input modulation indices of one and five, in the presence of noise. For the first time in the literature, the effect of additional output filtering following the ideal phase-coherent loop is discussed. Finally, the requisite modulation characteristics for an improved threshold in a phase-locked loop discriminator are presented, followed by a brief description of the approaches which may be taken in the design of such a system.

  • The Astronautic Chart

    Publication Year: 1960 , Page(s): 34 - 37

    The Astronautic chart is a nomograph or alignment chart so arranged that a single straight line marks off values of the velocity, mass, mean distance, period, and acceleration of any two-body orbiting system. It is illustrated with numerous examples of orbits of planets about the sun, moons about their planets, and artificial earth satellites. All scales give correct values at the extremities of the minor diameter of the elliptical orbit. In the case of binary stars where the masses are comparable, the scales also give correct values of the total mass, total separation, relative velocity, and relative acceleration.

  • A Versatile PAM/PDM Decommutation Station

    Publication Year: 1960 , Page(s): 38 - 40
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1405 KB)  

    The growing complexity of data-handling systems and the need for less complicated and smaller decommutation devices led to the development of the PAM/PDM decommutation station shown in Fig. 1. The PAM/PDM data-handling capability of this station is 100 channels and, for the system shown, the utilized panel space is 26 1/4 inches. View full abstract»

  • The Navy's Portable Satellite Tracking Stations

    Publication Year: 1960 , Page(s): 41 - 45

    The stations described recover doppler frequencies to an accuracy of one part in 109 and subcarrier oscillator frequencies to 15 kc bandwidths. Coherent phase detection and a tracking local oscillator to minimize required reception bandwidth maximizes signal sensitivity. Station portability accommodates rapid changes of location as dictated by satellite projects and the flexibility of the receiving and recording equipment due to unitized construction permits inexpensive modifications to accommodate present and future satellite programs.

  • Ground Antenna for Space Communication System

    Publication Year: 1960 , Page(s): 45 - 54

    The accurate tracking and telemetering of space probes requires the use of very sensitive receiving equipment and large antennas. The TRAC(E) system developed by the Jet Propulsion Laboratory utilizes an 85-foot-diameter, equatorially mounted, parabolic reflector. The antenna, similar to those used for radio astronomy, is located near Goldstone Lake near Barstow, Calif. The mechanical and electrical characteristics of the antenna and its subsystems are discussed, and its performance and the way it was used in tracking the lunar probe Pioneer IV are described. Limitations imposed on the space communication system by the ground antenna are discussed, and possible methods of improvement are listed. View full abstract»

    The Inter-Range Instrumentation Group (IRIG) was established in 1952 by the commanders of the United States guided missile test ranges, principally for the purpose of facilitating the interchange of information on range instrumentation. Today, the IRIG consists of a Steering Committee and ten Technical Working Groups. Among other activities, the IRIG prepares and disseminates recommended standards and other documents (such as glossaries of terms and catalogs of range instruments) to advance the range instrumentation art.

    One of the ten Technical Working Groups of the IRIG (Inter-Range Instrumentation Group, established by the commanders of the United States guided missile test range), is the Telemetry Working Group (TWG). Among other activities, the TWG has prepared several System Standards that have been published as IRIG Recommendations. View full abstract»
