七十年代,美航宇局在应用技术卫星计划中进行了广泛的通信试验,为卫星通信技术的发展做出了重大贡献。现在,为了迎接信息社会的到来,美航宇局又制定了一项目的在于发展高级通信技术的试验计划。在这项计划中准备研制的卫星称为“高级通信技术卫星”(ACTS)。本文将首先简单地介绍卫星通信技术的发展现状,然后着重描述在高级
In the 1970s, the United States Aerospace Bureau carried out extensive communications experiments in the Applied Technology and Satellite Program, making a significant contribution to the development of satellite communications technology. Now to meet the information society, NASA has also put in place a pilot project aimed at developing advanced communications technologies. The satellite to be developed in this plan is called the Advanced Communications Technology Satellite (ACTS). This article will first briefly introduce the status of the development of satellite communications technology, and then focus on description in advanced
