Satellite tribe dressed in gold (7)
I believe the answer is:
orbiter
'satellite' is the definition.
(I've seen this before)
'tribe dressed in gold' is the wordplay.
'dressed' indicates an anagram ('dress' can mean 'prepare').
'in' is an insertion indicator.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'tribe' with letters rearranged gives 'rbite'.
'rbite' placed into 'or' is 'ORBITER'.
(Other definitions for orbiter that I've seen before include "Non-landing spacecraft" , "Satellite perhaps" , "One goes round" , "Circling spacecraft" , "Space vehicle" .)
