摘要
针对日益增长的北斗授时时统零值标定需求,在建立北斗授时链路时间传递模型的基础上,深入研究了5种北斗授时时统零值标定技术的标定原理及其优势和不足,并利用不同型号北斗授时时统开展了零值标定实验验证。结果表明,5种零值标定技术可分别实现不超过0.1 ns、0.9 ns、1.5 ns、2.0 ns、2.8 ns的零值标定,分别适用于少量超高精度标定、小批量较高精度标定、大批量自动化标定、日常巡检标定、快捷粗略标定等不同类型的北斗授时时统零值标定应用场合,具有良好的工程应用价值。
In order to meet the growing demand for zero-value calibration of Beidou timing system,based on the establishment of Beidou timing link model,the testing mechanism,advantages and disadvantages of five Beidou timing system zero-value calibration technologies are analyzed in depth,and the zero-value calibration experiments are carried out using different Beidou timing systems.The results show that the five zero-value calibration technologies can achieve zero-value calibration of no more than 0.1 ns,0.9 ns,1.5 ns,2.0 ns,2.8 ns,respectively.They are suitable for different types of zero-value calibration applications such as small quantities of ultra-high precision calibration,small quantities of high accuracy calibration,large quantities of automated calibration,daily patrol calibration,fast and rough calibration,and have good engineering application value.
