SATELLITE-BASED DIRECT ACCESS TELECOMMUNICATIONS SYSTEM

摘要

A direct access satellite telecommunications system employs one or more telecommunications satellites in geosynchronous orbit. Small, low-cost user terminals are located at the user's premises and permit two-way telecommunications via user links. Access links provide satellite telecommunications to larger gateway stations as well as a network control center. Gateway stations store user information and provide connection to terrestrial telecommunications networks. In operation, the network control center allocates satellite bandwidth and power to setup the access and user links, with a minority of the satellite's power being allocated to the access links, and a majority of the power being available for the user links.
