Thanks for the excellent work! Can you explain what EmpFile means and How to get the EmpFile(hksc141g.nav)? I can download roverMeasureFile from https://github.com/IPNL-POLYU/UrbanNavDataset#urbannav-hk-deep-urban-1,and baseMeasureFile from https://www.geodetic.gov.hk/en/rinex/downv.aspx. But I can't find EmpFile. Looking forward to your reply! thanks!

Hi @Eric-Zhao1, thank you for your interest. The EmpFile stands for ephemeris file. You can download broadcast ephemeris either from SMO or from NASA website and convert it into .nav file through RTKCONV from RTKLIB. Feel free to reach out if you have further questions.

Best, Xikun
