卫星平台的标准化

STANDARDIZATION OF SATELLITE PLATFORMS

中国空间技术研究院（ＣＡＳＴ）通过已经研制成功并经过空间飞行考验的卫星平台和未来将研制的卫星平台，进行适当的修改后，形成标准化的卫星公用平台．ＣＡＳＴ拟建立４个系列６种公用平台．这就是以“东方红３号”卫星平台为基础的地球静止轨道卫星公用平台ＤＪＳ－１、以未来大容量通信卫星平台为基础的地球静止轨道卫星公用平台ＤＪＳ－２、以“资源一号”卫星平台为基础的太阳同步轨道卫星公用平台ＴＴＳ－１、拟议中的新一代太阳同步轨道卫星公用平台ＴＴＳ－２、返回型卫星公用平台ＦＳＷ－２和以“实践５号”卫星平台为基础的小卫星公用平台ＣＡＳＴ９６８． 本文首先阐述卫星标准化的三种形式──通用化、系列化和组合化的基本概念和卫星实现标准化的必要性；其次，介绍国外公用平台的现状，提出建立卫星公用平台的基本原则；最后给出６种公用平台的自重、平台尺寸、可支承的有效载荷重量、总功率、有效载荷可用功率、姿态控制精度、测控能力、推进剂携带量、设计工作寿命、与运载火箭的相容性等主要性能参数及其应用前景．

The paper, at first, presents the basic concept of three forms of standardization, i.e. generalization, senation and combination, or modularization and the necessity of the realization of satellite standardization, secondly introduces the status of the foreign satellite common platforms, thirdly formulates the basic principles on establishment of satellite common platforms, and finally gives the CAST's six common platforms performance parameters, including weight, size, supportable payload weight, total power output, power available to payload, telemetry and remotecommand, propellant available, operation lifetime and compatibility with launcher, and the application prospects.
