Journal Article
Upper air densities obtained by means of rockets and satellites in the region from 100 to about 800 km are presented.
Journal Article
Solar stream distortion of the geomagnetic field, polar auroras, electrojets.
Report
An application of a new mathematical technique, based on the theory of dynamic programming, to the computational solution of trajectory problems. This method has already resolved many problems, seemingly inaccessible to the conventional methods of th...
Report
A derivation of three-dimensional error equations for a locally vertical inertial navigation system based on the three-gimbal and five-gimbal concepts. The error equations are presented for undamped and damped systems. The resulting analytical expres...
Report
Background information supplementing the cost estimates for communications satellites given in RM-2709-NASA, "Communications Satellites: An Introductory Survey of Technology and Economic Promise."
Report
A description of a guidance or orbital control process, particularly applicable for use with a 24-hour communications satellite. The process deals with certain of the guidance problems involved in such a satellite, namely, the determination of the di...
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
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
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
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.
