本文讨论了目前全球（和区域）导航卫星系统（GNSS）所采用的姿态模式和用于描述它们的模型，沿着与星座特定的航天器主体框架的定义。全球导航卫星系统国际服务组织提出了一个标记航天器主轴的统一惯例，从而对偏航操纵模式下的所有全球导航卫星系统卫星的标称姿态有一个共同的表述，而不论其具体轨道和星座。本文档中定义的约定为ANTEX（天线交换）格式的IGS绝对相位中心模型的多GNSS版本中的天线相位中心偏移和变化的规范提供了基础。为便于对全球导航卫星系统观测结果和卫星激光测距测量结果进行联合分析，除了所有全球导航卫星系统星座的代表性天线偏移值外，还提供了与国际地球同步系统特定航天器框架约定一致的激光后向反射器阵列坐标。(C)2015年空间研委会。由Elsevier Ltd.发布。这是CC BY-NC-ND许可证下的开放获取文章（http：//creativecommons.org/lic，enses/by-nc-nd/4.0/）。
This article discusses the attitude modes employed by present Global (and Regional) Navigation Satellite Systems (GNSSs) and the models used to describe them along with definitions of the constellation-specific spacecraft body frames. A uniform convention for the labeling of the principal spacecraft axes is proposed by the International GNSS Service (IGS), which results in a common formulation of the nominal attitude of all GNSS satellites in yaw-steering mode irrespective of their specific orbit and constellation. The conventions defined within this document provide the basis for the specification of antenna phase center offsets and variations in a multi-GNSS version of the IGS absolute phase center model in the ANTEX (antenna exchange), format. To facilitate the joint analysis of GNSS observations and satellite laser ranging measurements, laser retroreflector array coordinates consistent with the IGS-specific spacecraft frame conventions are provided in addition to representative antenna offset values for all GNSS constellations.
