Hi,
I have just noticed that the data was found at http://www.beidou.gov.cn/xpnavdata.rar
The satellite was built by BD7ILZ's company and launched on 2016.11.10. The data is recieved from the Crab nebula.
If you are interested on the data I am happy y to translate the readme.txt and related information.
