    This paper describes a method for quickly and quite accurately estimating the time that the moon is in common view of two stations on earth during the lunar day. A mathematical derivation tion and a detailed description of the method are given, together with a nomogram which simplifies the calculation. A sample problem is solved and a short table of time availability for several links of interest ... View full abstract»

    This paper presents a general discussion of phase-locked-loop thresholds and tracking ranges. A typical phase-locked loop and its linear equivalent are introduced, and there is a brief discussion of application of the root locus method and the Bode amplitude plot to this circuit. Calculation of the maximum allowable deviation is considered for both phase and frequency modulation (sinusoidal). The ... View full abstract»

    With the development of low-noise amplifiers, the noise contribution of the antenna has become a limiting factor on system performance in many applications. This paper discusses the calculation of the equivalent noise temperature contribution of parabolic reflector antennas using their radiation characteristics and environment. As an example, the equivalent noise temperature of an 85-foot reflecto... View full abstract»

    This paper derives relationships which express the contribution of ground-receiver noise and round-trip transit time to the errors in two-way radio Doppler measurements. Only one method of Doppler measurement is considered. This is the method of counting the number of cycles in a given time interval. From this measurement the signal frequency may then be determined. In usual tracking systems this ... View full abstract»
