Greetings, Orekit community,
I am new to Orekit and trying to reproduce 02-orbit-determination-example.ipynb to use it for a similar ODP using SLR data. But when I try to load station data, the code hereunder gives me an error, and I need your help. Your help/direction is much appreciated!
Code:
stationFile = ‘SLRF2014_POS+VEL_2030.0_180504.snx’
stationEccFile = ‘ecc_xyz.snx’
import slrDataUtils
stationData = slrDataUtils.parseStationData(stationFile, stationEccFile, startCollectionDate)
display(stationData)
error:
…indexing.py:925: PerformanceWarning: indexing past lexsort depth may impact performance.
return self._getitem_tuple(key)
KeyError Traceback (most recent call last)

3362 except KeyError as err:

The above exception was the direct cause of the following exception:
