| 摘 要： | 探讨了CEI技术在飞船交会对接远程导引段的高精度定轨与实时监控的能力。仿真结果表明:精密定轨中采用可视弧段较长的单站可使相对位置精度达百米以内,速度达厘米/秒级。采用单一绝对扩展卡尔曼滤波器的方案进行实时轨道计算,采用滤波稳定后固定模糊度的方法可以使相对轨道位置精度达十米级,速度精度达厘米/秒级,事后及实时的轨道精度均满足远程导引段的精度指标。

| Abstract: | Rendezvous and docking between Shenzhou spaceship and target spacecraft are the goals in the next phase of Chinese space exploration.Connected-element interferometry(CEI)is a method of passively tracking directions and has the advantages of short baselines,flexible station-network distribution,and nearly real-time processing.It allows real-time precision orbit determination for spacecraft rendezvous and docking.We discuss the CEI-based orbit determination of a course under remote guidance leading to spacecr... |
