SPICE (NOLOADEDFILES) #709

Open liuli217217 opened 1 month ago

liuli217217 commented 1 month ago

Describe the bug I have followed the instructions to install Basilisk on Windows 10/Windows 11/Ubuntu 20.04, and I can successfully run multiple examples including scenarioBasicOrbit.py and scenarioGroundLocationImaging.py. However, when I try to run scenarioGroundDownlink.py, it always prompts me with the error message: ' Toolkit version: N0065 SPICE (NOLOADEDFILES) -- At least one SPK file needs to be loaded by SPKLEF before beginning a search. A traceback follows. The name of the highest level module is first.spkezr_c --> SPKEZR --> SPKEZ --> SPKGEO --> SPKSFS.'

Could you please help me understand the reason for this and how to resolve it? Thank you."

This means the JPL Spice files were not installed. Be sure to install git-lfs before cloning the repo to ensure the spice file is also pulled. See http://hanspeterschaub.info/basilisk/Install/pullCloneBSK.html.
