摘要
授时技术在许领域都有重要应用。基于对授时技术和双星系统的分析 ,在文中给出了基于双星系统的卫星单向授时方案 ,并进行了误差分析。根据双星系统的误差预算 ,本方案的授时精度可达 30 ns。此外 ,还进一步归纳了通用授时技术对双星系统的要求。
Timer transfer is widely applied in many fields.Based upon the analysis of time transfer methods and Twin Synchronous Satellites system,a specified scheme is presented and the error performance is analyzed.According to the errorbudget,error degree of 30ns accuracy can be obtained by the timer transfer scheme provided here.Finally,the requirements of general timer transfer methods towards dual satellite system are further concluded.
