Multiple Access Techniques Add Flexibility

Washington-Efficiency and flexibility of the Intelsat communications satellite global network will be greatly enhanced by an important technical innovation in “multiple access” which is being introduced later this year. For the first time, any suitably equipped earth station will be able to communicate with any other similarly equipped earth terminal within view of a single satellite.

New Technology for Civil Uses Evolving

Washington-New communications satellite technology that will be needed in the late 1970s and in the 1980s is becoming increasingly well-defined, at least for most civil applications. The technological trends for a broad spectrum of next-generation military communications satellites expected to see service during the same period are now being defined in a Pentagon-sponsored "summer study,” scheduled for completion this week.

Changes in Design, Higher Costs Expected with New Allocations

Recent propagation experiments in the newly assigned 11/14-gc. and 20/30-gc. communications satellite bands provide an indication of the technical problems involved in expanding into the new frequencies later in this decade. Even more extensive experiments are planned during the next several years.

Global Military System Approval Expected

Washington-Pentagon approval is expected shortly for the development of an operational UHF military satellite communications system with global coverage for Navy fleet use and for tactical communications with Navy and USAF aircraft.

TV Education Role Gains World Interest

Worldwide interest in satellite systems for television distribution as the new frontier for rapid national development by mass education and instruction is gaining momentum. In the mid-1960s, India started looking to satellites as the answer to the country’s monumental top-priority problem:

British Shift to Communications Satellites

London-British defense establishment is taking the lead here in development of communications satellites, with the Skynet long-range communications system setting a trend away from previous concentration on scientific satellites.

Final Approval of Esro System Nears

Paris-European Space Research Organization (ESRO) has completed definition of the advanced telecommunications satellite scheduled for launch by 1980 to serve the needs of the European Conference of Post and Telecommunications Administrations (CEPT) and the European Broadcasting Union (EBU).

Growing, Reorganized Intelsat Ponders New Satellite Series

Washington-International Telecommunications Satellite Consortium, with 80 member nations and still growing, is now starting to consider the next satellite series for its global system after two years of tortuous labor on a basic reorganization.
