An algorithm with periodic item for steering UTC(NTSC) to UTC

In order to steer master clock in timekeeping laboratory, it is necessary to identify a suitable algorithm for steering UTC(K) to UTC for a period of 45 days with 5-day latency. An algorithm is proposed to modify a traditional quadratic polynomial prediction model whose random error term is represented by a linear combination of periodic term. In the case of steering, the performance of the underlying algorithm is examined in depth, together with a comparison against simulated results of QP.
