Aerospace & military: setting targets throughout the region

Article Abstract:

Aircraft development and space exploration are perceived by many Asian countries as what will drive their technology into the next century. Japan sent its first spacecraft around the moon in 1990, and China launched its first commercial payload for a foreign company, a communications satellite for a Hong Kong-based consortium that sent the first direct-broadcast television images to all of Asia. Japan has targeted fighter planes, commercial air transport and space technology in its attempts to become a top aerospace power. Singapore, Indonesia and Malaysia hope to gain entry to aerospace markets by first becoming centers for maintenance and repair, then manufacturing smaller components, then assembling aircraft from kits, and finally designing and building complete aircraft domestically. The goals for these and other Asian countries in aerospace and military areas are discussed.

Communications satellites: orbiting into the '90s

Article Abstract:

Revolutionary engineering advances are taking place in satellite communications. Scarce spectrum resources will be used much more efficiently due to sophisticated switchboards that exploit both high-frequency regions and frequency reuse. Experimental satellites have spot beams that are so narrow and so efficient that they will provide 10 or more times the capacity of one old-style beam. Powerful new coding schemes are increasing capacity more by compressing voice, data, video, and music with no loss of quality. The changes taking place in satellite communications are being compared to the changes that took place in land communications with the advent of the optical fiber.

Small, low-cost earth stations: a major trend

Article Abstract:

Satellite communication systems increasingly use small, inexpensive earth stations for domestic networks in response to both competition and regulatory changes. These VSATs (very small aperture terminals) are flexible and more economical than fiber-optic cable for thin-route communications, and can be linked with fiber-optic networks. International satellite communications continue to grow at 10 to 12 percent yearly.
