Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Aerospace Science and Technology Corporation. This standard by the National Aerospace Technology and Application of Standardization Technical Committee (SAC/TC425) centralized. This standard was drafted. Shanghai Institute of Satellite Engineering. Drafters of this standard. Wu Dong, Li Jin Group, Zong Yi Yan, Rong Shen Kang Gu Tao Tao strong, Shuxiao Chen, Zhang L, Li Qiang.

Introduction

This standard belongs to China Aerospace national standards. China Aerospace national standards applicable to national standards in the field of aerospace and revision Management, covering the management of space, space technology, space applications and services of the three fields, is to guide spacecraft and launch vehicle project management, engineering research System, space launch services, in-orbit satellite applications based activities. With the development of satellite technology development and national defense, economic needs and the requirements of the satellite with more precise and sophisticated optical, thermal control, navigation and positioning Control and longer service life. The pollution is an important factor in satellite reliability, safety impact, long-term cumulative effects of contamination Movies Its performance impact of satellite payloads, and even shorten the life of satellites and their payloads. Therefore, in the development of all aspects of satellite products Of pollution control it is necessary. Satellite pollution prevention technical requirements

1 Scope

This standard specifies the required satellite development of the whole process of pollution prevention projects and their technical requirements. This standard applies to the entire star development, subsystems and components (including equipment, parts) can also refer to use.
