CODE rapid product series for the IGS

CODE, the Center for Orbit Determination in Europe, is a joint venture of the following four institutions: Astronomical Institute, University of Bern (AIUB), Bern, Switzerland;Federal Office of Topography swisstopo, Wabern, Switzerland; Federal Agency of Cartography and Geodesy (BKG), Frankfurt a. M., Germany; Institut für Astronomische und Physikalische Geodäsie, Technische Universität München (IAPG, TUM), Munich, Germany. It acts as a global analysis center of the International GNSS Service (IGS). The operational computations are performed at AIUB using the latest development version of the Bernese GNSS Software (Dach et al., 2015). In this context a rapid solution series is generated considering all active GPS, GLONASS and Galileo satellites. It contains 24 hours of observed orbits and published at the day after the observations.欧洲轨道确定中心（Center for Orbit Determination in Europe，简称CODE）是由以下四家机构联合组建的机构：瑞士伯尔尼大学天文研究所（Astronomical Institute, University of Bern, AIUB）、瑞士瓦伯恩的联邦地形测绘局swisstopo（Federal Office of Topography swisstopo）、德国美因河畔法兰克福的联邦测绘与大地测量局（Federal Agency of Cartography and Geodesy, BKG）以及德国慕尼黑工业大学天文与物理大地测量研究所（Institut für Astronomische und Physikalische Geodäsie, Technische Universität München, IAPG, TUM）。 该中心作为国际GNSS服务（International GNSS Service, IGS）的全球分析中心开展运行，其业务计算工作由AIUB依托Bernese GNSS软件的最新开发版本完成（Dach等，2015）。 在此背景下，研究团队生成了一套快速解算序列，涵盖所有现役GPS、GLONASS及Galileo卫星，该序列包含24小时观测轨道数据，并于观测次日对外发布。
