GIOVE-B是未来欧洲全球导航卫星系统伽利略的两颗测试卫星之一。GIOVE观测合作网络（刚果）是由德国航空航天中心和联邦制图和大地测量局建立的具有GIOVE能力的接收器全球跟踪网络。该网络为使用伯尔尼GPS软件的修改版本在2009年6月29日至10月27日期间精确确定GIOVE-B卫星的轨道提供了基础。不同的弧长和轨道参数集进行了测试。这些测试表明，九个辐射压力参数的完整集合比五个参数的缩减集合产生更好的性能。对于5天溶液的中心日，可以证明约1至2分米的内部精度。轨道预报的精度约为1米，预报周期为24小时。卫星激光测距（SLR）的外部验证显示残差水平为12 cm。预计最终轨道的精度将达到几分米的水平。
GIOVE-B is one of two test satellites for the future European Global Navigation Satellite System Galileo. The Cooperative Network for GIOVE Observation (CONGO) is a global tracking network of GIOVE-capable receivers established by Deutsches Zentrum fur Luft- und Raumfahrt (DLR) and Bundesamt fur Kartographie und Geodasie (BKG). This network provides the basis for the precise orbit determination of the GIOVE-B satellite for the time period 29 June till 27 October 2009 with a modified version of the Bernese GPS Software. Different arc lengths and sets of orbit parameters were tested. These tests showed that the full set of nine radiation pressure parameters resulted in a better performance than the reduced set of five parameters. An internal precision of about one to two decimeters could be demonstrated for the central day of 5-day solutions. The orbit predictions have a precision of about 1 m for a prediction period of 24 h. External validations with Satellite Laser Ranging (SLR) show residuals on the level of 12 cm. The accuracy of the final orbits is expected to be on the few decimeter level.
