During activities such as aerospace engineering mission design and analysis, ground testing, on-orbit early warning and forecasting, and fault location, the space environment and its related... This terminology is frequently used by departments that propose space missions, develop spacecraft, produce space materials and components, and manage operations. The terminology used in the aerospace field has varied domestically over the past few decades, leading to communication difficulties among industry, academia, research, and application units. Differences in coordination and communication activities cause numerous inconveniences. Therefore, it is necessary to standardize the terminology related to the space environment in space activities. specification. In the drafting process, this document drew upon both the terminology explanations in widely recognized international standards and specifications, and existing mature domestic standards. Explanation of terms in relevant standards. The terminology used in this document mainly refers to the space environment and related terms that directly interact with spacecraft during spacecraft activities, and does not cover terms that may be related to spacecraft. Environments that affect the spacecraft's space environment but do not directly interact with the spacecraft. Space terminology. space environment 1.Scope This document defines the general fundamentals of space environment, space environment models, and space-related aspects involved in the field of spacecraft space environment and its effects. Terminology and definitions for environmental forecasting, space environment effects, space environment detection, and ground simulation experiments of space environment and effects. This document applies to the design, launch, and operation of spacecraft and space environment-related fields, including satellites, spacecraft, space stations, and space probes. This approach can also be adopted in fields related to the effects of the space environment, such as launch vehicles.2 Normative referencesThis document has no normative references.3 General Basics3.1 General Terminology 3.1.1 space Space The universe beyond Earth's atmosphere.
