本文叙述了ERTS计划的基础——从准备到目前所确定的系统和初步设计的结果。讨论了ERTS数据在空间方面,光谱方面和暂态方面的关系;也讨论了它们对实现一个系统的实际情况的关系。在概述了飞船、它的传感仪器和各分系统之后,还简述了地面数据处理系统(GDHS)。在系统的设计中可看出数据的分析和散发情况,结论是:目前的GDHS概念为在此领域内的继续努力提供了有益的基础。
This article describes the basics of the ERTS program - from preparation to the system and preliminary design results identified so far. The relationship between spatial, spectral and temporal aspects of ERTS data was discussed. Their relationship to the actual situation of a system was also discussed. After an overview of the spacecraft, its sensing instruments and subsystems, the ground data processing system (GDHS) was also outlined. The analysis and dissemination of data can be seen in the design of the system and concluded that the current concept of GDHS provides a useful basis for continued efforts in this area.
