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
