  • Power supplies for space vehicles

    Publication Year: 1961, Page(s):179 - 188
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1269 KB)

    The requirements for electrical power in space vehicles over the next five years are reviewed and estimated figures given with particular reference to power/weight ratio. Vehicle life duration and its effect on choice of supply are discussed. Problems encountered in space vehicles due to environmental conditions, e.g. temperature, radiation, zero gravity, etc., are then pointed out. The available ... View full abstract»

  • The advantages of attitude stabilization and station keeping in communications satellite orbits

    Publication Year: 1961, Page(s):193 - 202
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1134 KB)

    The power demands for broadband transmission of multichannel telephony are far greater than those for telemetry. Satellite communications repeaters might require inputs of the order of hundreds of watts and the weight and cost of solar cells to provide this power is considerable. Attitude stabilization is one method of economy in that it makes possible the utilization of satellite transmitting aer... View full abstract»

    The reception pattern of a short dipole above the F layer is considerably modified by refraction in the ionized medium and has the form of a cone with sharply bounded edges modulated by a fine interference pattern. The properties of this reception pattern are discussed and suggestions are made for satellite experiments based on this phenomenon. It is shown that a variety of techniques are availabl...

  • A proposal for an active communication satellite system based on inclined elliptic orbits

    Publication Year: 1961, Page(s):209 - 225
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1978 KB)

    Satellites in the 24-hour stationary orbit will have to be stabilized in attitude relative to the earth, and kept in the correct station in their orbit, if their full potential is to be realized. If attitude stabilization and station keeping can be achieved, there are many advantages in using inclined elliptic orbits; this paper describes the design of a communication satellite for use in a 63-deg...

  • Some international aspects of satellite communication system planning

    Publication Year: 1961, Page(s):227 - 229
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (399 KB)

    The work of the organizations concerned with international planning of telecommunication systems is described. The prime need for satellite communication systems is the allocation of frequency bands, preferably on an exclusive basis, but some sharing with low-power radio-relay systems may be necessary. Other aspects requiring international agreement include the minimization of interference with ot... View full abstract»

  • Inertial systems in space vehicles

    Publication Year: 1961, Page(s):231 - 239
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1167 KB)

    This paper discusses the use of inertial elements in space vehicles for attitude control and navigation. Some limitations of inertial systems in this environment are described and it is shown that inertia alone is not adequate for most space applications. However, the use of inertia to bridge the gaps between information from other sources can simplify the requirements for other sensors in the sat... View full abstract»

    The radiation environments encountered by a satellite according to its orbit are summarized. The breakdown of high-energy radiation on meeting matter is described, indicating the mechanisms and nature of damage caused to equipment. An argument is presented to show that screening against hard radiation is inefficient and uneconomical. Estimates are given of the life of a transistor¿the most suscep... View full abstract»

  • Cosmic ray measurements in the U.K. scout I satellite

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (612 KB)

    The main purpose of this experiment is to make accurate measurements of the primary cosmic ray energy spectrum and of the way in which this spectrum changes as a result of modulation by the inter-planetary magnetic field. The cosmic ray intensity will be measured as a function of latitude and longitude using Geiger-Muller counters, which respond to the total flux of primary particles, and a Cerenk...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (897 KB)

    Three experiments in Moon reflection using 1 kW v.h.f. transmitters and the Jodreil Bank radio telescope are described. The results are discussed in terms of practical long-distance communication circuits using the Moon as a passive reflector. Consideration is given to the optimum frequency, type of modulation, aerial size, etc., for economic utilization of such a circuit. View full abstract»

    The principles of operation of the maser are reviewed with emphasis on its ability to give low-noise amplification. The properties of the comb structure travelling wave maser are discussed and related to the microwave ¿space window¿, with special reference to an S-band amplifier which has been constructed. The performance of a receiver, incorporating a maser or a parametric amplifier, is analyse... View full abstract»
