The satellite navigation system uses spread spectrum codes such as Gold code, Weil code and memory code. Each code has the property of having a certain length. Therefore, the code with the required length is generated using truncation or insertion. The Kasami code is optimal in terms of Welch's lower bound and is used only in QZSS centimeter-level augmentation service signals. Since Kasami codes have a small number of code families, it is difficult to find candidates for spread spectrum codes using truncation. Therefore, in this paper, we propose a new method for creating spread spectrum code candidates. The correlation results are compared with the Kasami code-based spread spectrum code and the Weil code used in BDS.
