I was running the GPS satellite tracking code yesterday, it ran for a few hours, with no issues until this:

2021-03-20 15:31:15 ERROR ATATools.ata_control: /ephemeris got error: Command failed - ephemeris generation failed - The source, GPS-BIIR-8---PRN-16-, was not found or no tracks generated.
Traceback (most recent call last):
  File "/home/obsuser/miniconda3/envs/ATAobs/lib/python3.8/site-packages/ATATools/ata_rest.py", line 71, in _do_op
    raise ATARestException(json[cls.RETURN_MSG_KEY])
ATATools.ata_rest.ATARestException: Command failed - ephemeris generation failed - The source, GPS-BIIR-8---PRN-16-, was not found or no tracks generated.

During handling of the above exception, another exception occurred:

@tkoumrian Is there a log file where the exceptions can be read?
