Yes, but don't go too far. Gaobo disclosed that the polynomial generated by the current civil short code channel coding is not what Beidou designers want, but it will not cause substantial harm to the safety of Beidou-2, especially the safety of military applications.

Gaobo incident:

Gao Bo, a female student who graduated from the Department of Precision Instruments in Tsinghua University, cracked the channel coding rules of the Beidou second-generation positioning and navigation satellite in China during her doctoral studies at Stanford University, and subsequently published many high-level papers, which were commended by the American Aviation Radio Committee. When the news reached China, a stone stirred up a thousand waves and attracted a lot of abuse. Some people say that when she was studying in Tsinghua, she participated in the Beidou project. In the United States, all the research was about traitors and traitors who ate outside.
