The Skyfield conversion from TEME to ECEF is tested against an example calculation from a recent update to the SGP4 algorithm. See the comment above this test for a link; the test itself includes the numbers themselves: python-skyfield/skyfield/tests/test_earth_satellites.py Lines 67 to 99 in aa59e2d Could you explain which numbers you would like Skyfield to print in your own case, and which numbers it is printing instead for comparison? |

The TLE file I attached is assembled by myself. Those TLE data are old, I requested those data via email. Try the first four set of TLE data instead. I have given sat PRN number to each set of TLE data. Note that some of them contains two versions of TLE data for a specific satelltie, you can try any one of them if you wish, just don't use both. |

Hi there,
I am looking for a way to convert the coordinates in TEME frame to ECEF frame. I got the code which utilized both sgp4.api and skyfield.sgp4lib to do the conversion, but the converted coordinates are not accurate as I have the true ECEF coordinates for comparison. The code is provided below. I wonder if this piece of code should be modified since it was published online in 2018.
Many thanks,
Hongzhao
