Reviewer 2 Report
This article proposed one method to mitigate the multipath error based on the TR algorithm which has good performance on the performance improvement. Attitude determination as one example for the multipath mitigation effect is good but not clear enough to verify the algorithm performance. This point is quite important to validate the proposed TR algorithm.

Reviewer 3 Report
This paper focuses on the periodic variation of multipath error depending on the satellite's orbit and elevation angle, and improves the multipath error with Tikhonov regularization and cyclic regularization parameter reference.
Chapter 1 provides sufficient background and related research.Chapter 2 describes the proposed method well.Chapter 3 describes the evaluation of the proposed method applied to real data and shows that the proposed method improves multipath error and attitude estimation performance.Chapter 4 summarizes the results.
Mainly in Chapter 3, there are many parts that are a little difficult to understand due to insufficient explanation. However, minor modifications will clarify them.
