Report
An examination of the telephone tollrate changes likely to follow the cost reductions made possible by the use of satellite communications systems. Only a tenuous relationship exists today between costs and rates for particular telephone services bec...
Report
An examination of the possibility of Echo-type satellites maintaining their shape by acquiring negative electrostatic potentials in the outer Van Allen belt.
Report
An outline of the problems of public policy raised by the development of satellite-communication techniques.
Report
Discusses the problems of foreign participation in a communication satellite system from the standpoints of policy formulation and agreement negotiation.
Report
An approximate solution to the orbit of an artificial earth satellite, taking into account the oblateness of the earth (i.e., its departure from a spherical shape). The technique used is to simplify the nonlinear differential equations of celestial m...
Report
A discussion of the ability of communications satellite systems to provide broadband, long-distance communications at microwave frequencies without depending on intermediate ground-relay stations.
Report
Introductory remarks presented at the Symposium on Possible Uses of Earth Satellites for Life Sciences Experiments at Washington, D.C., May 14-17, 1958. Problems of satellite experiments are discussed: space environment, satellite package costs, an...
Report
A discussion of the basic objectives of the current, planned, and predictable programs of scientific research in outer space. The suitability of satellites and rockets in various roles of data collection is considered, and the importance of these da...
Report
A review of the mechanism of meteor-burst propagation, and a discussion of the operating principles of typical systems. A model of burst occurrence and duration is constructed. Total burst time and duty cycle are computed, for given intervals of time...
Report
An account of the more important recent advances in high-altitude research based on rocket and satellite data and a presentation of a quantitative picture of our current knowledge of atmospheric physics. Some findings which have not yet been properly...
Report
A study of the minimal velocity impulse which must be imparted to satellites on circular and elliptical orbits to "knock them out of orbit" and cause them to impact the earth. It is concluded that the idea of "shooting down an unfriendly satellite" m...
Report
An application of linear and dynamic programming to solve numerous communication system problems. Treatments for communication system extension problems and for equipment replacement policies are given, and various generalizations are indicated....
Report
A proof that the functional equation technique of dynamic programming can be used advantageously in analyzing weighted pulse-code modulation (WPCM) communication systems. WPCM differs from normal PCM in that the amplitude of the transmitted pulses re...
Report
A study of the functional-equation technique of dynamic programming to analyze (1) some extensions of the Kelly-Bellman-Kalaba model of communication and (2) a null-zone reception system. The role of suboptimum systems is emphasized....
Report
This research memorandum is the product of a feasibility study undertaken by several members of the RAND technical staff. The basic idea of using a spin-stabilized panoramic camera in the manner described herein was developed by M. E. Davies in the spring of 1957.
Report
A discussion of the requirements for establishing an artificial satellite of the moon.
Report
A discussion of the developments proposed after the 1953 Soviet agricultural reforms to reduce the importance of private production in total food supply. In particular, this study discusses USSR plans to increase the production of specific crops and ...
Report
A RAND Corporation study that delineates the problems of water supply and indicates the more important areas of research in this field.
Report
This report comprises a discussion of problems and requirements of instrumentation for communication between ground stations and a man-made satellite on an orbit above the earth's equator.
Report
More than eleven years before the orbiting of Sputnik, history's first artificial space satellite, Project RAND released its first report: Preliminary Design of an Experimental World-Circling Spaceship (SM-11827), May 2, 1946.
