This report presents the results of a theoretical analysis of a frequency-hopping, multiple-frequency-shift-keyed, spread-spectrum communication system using a nonprocessing communication satellite transponder. A large number of users are assumed to be hopping pseudo-randomly about the transponder passband in time synchronization and approximate frequency synchronization. The users are assumed to ......

This Note describes in mathematical terms the dynamic geometry between a constellation of satellites deployed for ballistic missile defense (BMD) and the missiles the satellites are engaging. Formulas, readily translatable into computer code, are given for such engagement parameters as slant range, closing velocity, and line-of-sight incidence angle in terms of satellite and missile position and v......

Publisher: RANDPublished Time: RANDPages: 100The European Union plans to have its positioning, navigation, and timing (PNT) system, Galileo, in initial operation in 2008. As envisioned, Galileo will function and perform similarly to the U.S. Global Positioning System (GPS), the preeminent PNT system now in existence. Policy leaders and technical experts have been attempting to find cooperative way......

Standard equations for the determination of the changes in the orbital elements of nearly circular satellite orbits for two large, heavy satellites similar to Mercury. The lifetimes of these satellites, starting on orbits ranging in altitude from 75 to 150 n mi and inclinations from 0 to 90 deg, are given for several different Earth-atmosphere models.......

Hard facts and harder questions about cable television and satellite interconnection, expanded from a symposium leader's remarks at the October 1972 SMPTE Technical Conference.Under the severe FCC restrictions on importing distant television broadcast signals, how can urban cable systems attract subscribers?Neither advertiser-supported nor noncommercial locally originated programming seems able to......

The Department of Defense needs far more satellite communications capacity than it owns and thus must lease satellite communications services.Communications planners can use the "rule of thumb" set forth in this study to aid in making efficient satellite leasing decisions in the face of uncertain demand for satellite services.It is a simple, graphical technique.Extensions to the basic model show h......

A study to determine whether balloon-type communication satellites remain sufficiently stable to be economically competitive with other means of communication.During certain orientations of Echo I, perturbing forces due to solar radiation pressure and air drag operate in the same direction, so the decrease in perigee altitude is rapid.At other times, the opposing forces counteract each other.Examp......

A discussion of the requirements for establishing an artificial satellite of the moon. Such problems are considered as general orbit properties, limiting orbit parameters, transporting the satellite to the moon, attitude control during transit, and the visibility of the satellite on orbit.......
