Thank you for reaching out to us.
It should be the TR.AssetLocationLatitude and TR.AssetLocationLongitude fields.
The code looks like:
df = ld.get_data( universe = 'C}KY7309846678', fields = ['TR.AssetLocationLatitude.date','TR.AssetLocationLatitude', 'TR.AssetLocationLongitude'], parameters = {'SDate':'0D', 'EDate':'-1AW'}) df
You can use the Data Item Browser tool to search for other fields. Otherwise, you can contact the helpdesk team directly via MyAccount.
