Gao Xingxin was the first person to crack the coding rules used by the Galileo test satellite and the BeiDou generation of medium earth orbit satellites.
The U.S.-Japan summit just finished issuing a joint statement that attaches great importance to the security of the Taiwan Strait, and the military confrontation between the U.S. and China is taking shape, triggering national sentiments of discontent among mainland netizens against the U.S., as well as the former Tsinghua University professor who cracked the code of the Chinese Communist Party’s BeiDou satellite. Gao Xingxin, a talented woman who cracked the Chinese “BeiDou” satellite code, was once again called a “traitor” and became a hot search on Weibo recently.
Gao Xingxin is the first person to crack the coding rules used by the Galileo test satellites and the BeiDou generation of medium-earth orbit satellites. Originally from Harbin, Heilongjiang Province, she grew up in China and studied actuarial science at Tsinghua University before attending Stanford University in 2003, where she received her Ph. After receiving her doctorate, she decided to stay in the United States and changed her name to Grace.
In April 2007, China launched the first medium Earth orbit satellite belonging to its Beidou-1 system. Building on her previous successful technology, Xingxin Gao demodulated all three band frequencies (E2, E5b, E6) of the civil code broadcast on this M1 satellite, confirmed that all BeiDou-M1 codes were Gold codes, and deciphered that its code generator was a linear shift element return register.
She also applied these pseudo-garbled codes in a soft receiver to acquire and track BeiDou-M1 satellites.
In addition, during her doctoral studies at Stanford University, Xingxin Gao cracked the channel coding rules of the Communist Party’s BeiDou-2 positioning and navigation satellites, and subsequently published several papers and received recognition from the American Radio Committee for Aeronautics.
However, because Gao’s research involved the Chinese Communist Party’s cutting-edge defense technology industry, her findings were highly valued by the U.S. as an important tool in the fight against the Chinese Communist Party.
As a result, many Chinese netizens called Gao a “traitor” and were very unforgiving of her after the disclosure of the report. However, opponents of the CCP’s military expansion argue that Gao Xingxin’s approach helps to curb the CCP’s hegemony and contributes to the maintenance of international justice.
