摘要
文章对著名论文《采用卫星方式实现越洋通信》作了介绍,该论文发表在1959年3月的《Proceed-ing of IRE》杂志上,作者为J.R.Pierce和R.Kompfiner.该文概述了从那时以来卫星通信的发展.令人吃惊的是,在某些方面,基本想法在40年后没有太多改变.从理论上讲,大多数技术发展符合这些想法.实际上,技术的进步和显著的发展在一些领域,如空间段、地面段和发射工具等领域已经实现.今天,卫星通信已不再仅仅是技术人员的领域,它已经创立了一个行业,建立了相应的机构,通过协调制定了规则和标准,为许多人提供了就业机会和商业利益.
This paper proviedes an introduction to the classic paper ' Transoceanic Communication by Means of Satellites,' which was written by J. R. Pierce and R. Kompfner and appeared in the March 1959 issue of the Proceedings of the IRE. This paper also provides a periscopic view of satellite communications development since then. Surprisingly, in some aspect, the fundamental ideas have not changed much after 40years. Conceptually, most technical development falls within these ideas. Practically, however, technological advances and significant progress has been made in all areas of space segment, ground segment, and launch vehicles. Today, due to its impact and usefulness, satellite communications is no longer the domain of the technologists alone. Instead, it has created industries, established relevant institutions, coordinated regulations and standards, provided employment, and financially benefitted many persons. This paper addresses these issues, which have been indirectly created by the scientists and engineers who developed satellite communications.
