| 摘 要： | 短基线相位干涉测量是一种被动测角卫星定轨跟踪方法,测量精度高。利用该方法采用单组正交双基线对静地卫星的定轨精度进行了仿真计算,并分别采用物理延长东西基线和东西基线阵列两种方法来考察对卫星定轨精度的改进情况。仿真结果表明,物理延长东西基线可以显著提高定轨精度;若星下点与跟踪网相距较远,则东西向基线阵列可显著提高定轨精度,且该方法对我国北斗卫星群的整体定轨效果很好,能进行几十米级的定轨。 |
| 关 键 词： | 相位干涉测量 静地卫星 精密定轨 基线阵列 |

| Abstract: | Connected-element interferometry(CEI) is a passive angular tracking method,with its high measure accuracy it can be used in orbit determination and tracking.One set of short dual-orthogonal baselines was used to do lots of simulation work about GEO'orbit determination and two methods were used to improve the orbit determination accuracy,one method was enlarging east-west baseline,the other was using east-west baseline array.The simulation results indicated that the method of enlarging east-west baseline cou... |
