摘要欧洲开始了脉冲星时间驯服原子钟的项目计划,他们和国内一些团队都是基于传统折叠模式的脉冲星到达时间数据单元和脉冲星星历预报,进行开环的钟驾驭算法研究。结合计量学的特点和技术要求,提出了不同的技术实现方案。该方案能解决传统脉冲星观测的自回归和吸收效应等问题,并且全部观测的测量参数可溯源,为脉冲星时间闭环驾驭原子钟提供了可行性。

Abstract：Recently, the project of Pulsar Time Steering Atomic Clocks has begun in Europe. They and some domestic teams both are based on the traditional folding mode of Pulsar Data Unit of TOA (Time of Arrival) and Pulsars Ephemeris Prediction to study the open-loop clock control algorithm. Based on the characteristics and technical requirements of metrology, ar technical implementation plan is put forward. Our scheme can solve the autoregression and absorption effects of traditional pulsar observations, and all the measured parameters can be traced back to the linking, which provides the feasibility for the closed-loop control of the atomic clock by pulsars.

Key words： metrology pulsar time disciplined atomic clock pulsar data recording and reduce autoregression
