Abstract
En 中文
The cone error compensation algorithm and the sculling error compensation algorithm are two important components of the inertial navigation algorithm. At present, scholars have done a lot of research on cone error compensation, and have proposed many cone error compensation algorithms, but there are few studies on the compensation of the sculling error. So for this problem, this paper proposes a new operation method, which can convert the cone error compensation algorithm into the corresponding sculling error compensation algorithm with simple calculation. Taking four classical cone error algorithms as examples, we give the conversion process and conversion results. The conversion results are exactly the same as the derivation error compensation algorithms given by the derivation, which proves the effectiveness of the proposed method. The method avoids the complicated derivation process of the traditional sculling error compensation algorithm, significantly reduces the amount of calculation, and has strong engineering practical significance.
