空间目标轨道信息软件平台的建设

摘要

The space object orbit information is one of the most important elements in the space situational awareness. It serves as the basis for the space collision warning, the space debris environment model and many other space applications, as they are all related with the determination of space object orbits. In this paper, the Space Object Orbit Information Software Platform developed at Wuhan University is presented. At the present, the platform includes or is going to include the following functions: the satellite/ debris orbit determination (including the initial orbit determination) and prediction using multi-source data, the atmospheric mass density model calibration, the space collision warning and the rapid precision orbit propagation based on the semi-analytical method. The research advances in the software platform are summarized, and the development plans are discussed.%空间目标轨道信息是空间态势感知的重要要素,是空间碰撞预警、空间碎片环境模型和许多空间应用的基础.因而,空间目标轨道确定成为空间态势感知的主要任务之一.文章介绍武汉大学测绘学院正在开发建设的空间目标轨道信息服务软件平台,该平台拥有的主要功能有:利用多源数据的卫星/空间碎片轨道确定(包括初轨确定)与预报、大气质量密度模型精化、空间碰撞预警和半解析法快速精密轨道传播等.文章还针对软件平台功能的研究进展进行了综述,介绍了软件平台发展规划.
