首次太空飞行以来,哥达德(Goddard)空间飞行中心就一直以其数据捕获网为用户提供各种程度的保障.为了进一步满足先进的近地轨道卫星用户增强通信和测轨的需要,跟踪和数据中继卫星系统(TDRSS)网(TN)已发展成为一个演进网的计划的一部分.为了对1983年初发射一系列跟踪数据中继卫星做好准备,各种网的部件的大变更正接近实现,综合和试验阶段.综合的最后阶段要求对工作网的部件进行 TDRSS 飞行后试验,然后才能证明 NT 网的工作能够保障所有的用户.TDRSS 不同于旧网的研制方法,因为它是由商用和政府用部件组合而成的一个高度自动化闭环系统所构成.商用部份,即由中心地面终端监控地球轨道上的系列卫星,以便取代 NASA’S 现有地面上分布的地面终端.NALA 部分包括一系列部件,根据任务保障形合同,这些部件能够监测和控制整个网.本文已概述了该系统拟在80年代和到0年代满足用户科学试验需求的计划.
Since the first space flight, the Goddard Space Flight Center has been providing its users with varying degrees of security with their data capture network. To further meet the needs of advanced NEO users to enhance communications and metrology, The Data Relay Satellite System (TDRSS) network (TN) has been developed as part of a plan for an evolutionary network. In preparation for the launch of a series of tracking data relay satellites in early 1983, major changes in various network components are approaching implementation , Integration and testing phases The final phase of the integration requires that post-flight TDRSS pilots be tested on the components of the working network prior to justifying the work of the NT network to all subscribers.TDRSS differs from the development of the old network in that it is comprised of commercial and The government is made up of a highly automated closed-loop system of components, the commercial part of which is the series of satellites in Earth orbit monitored by a central ground terminal to replace NASA’s existing ground-based terrestrial terminals. The NALA section consists of a series of components , These components are capable of monitoring and controlling the entire network based on mission-assurance contracts. This article has outlined the system to be developed in the 1980s And to 0 years to meet the needs of users of scientific experiments in the plan.
