摘　　要：新一代高精度测定轨系统要求地面测控设备零值测量精度达到厘米量级,与目前测控通信领域典型的测距零值标定残差工程指标相比提高了约2个数量级。提出了一种基于多链路联合解算的扩频测控设备距离零值标定方法,可以解决传统的分段标校方法带来的误差累计。理论分析和外场测试验证标校精度可达到厘米量级,精度优于0.02m。The new generation high-precision orbit determination system requires centimeter-level delay calibration technology.Compared with the current system,the system delay measurement accuracy could be enhanced at least two orders.A multi-link combined calculation equipment delay technique which can avoid accumulate error of traditional segmentation calibration is proposed.The theoretical analysis and outfield test proves the calibration accuracy can reach the order of centimeter.The accuracy is better than 0.02 m.
