Movement of it reversed in satellite (6)
I believe the answer is:
motion
'movement' is the definition.
(I know that movement can be written as motion)
'it reversed in satellite' is the wordplay.
'reversed' says the letters should be written in reverse.
'in' means one lot of letters goes inside another.
'satellite' becomes 'moon' (moon is a kind of satellite).
'it' in reverse letter order is 'ti'.
'ti' put inside 'moon' is 'MOTION'.
'of' acts as a link.
(Other definitions for motion that I've seen before include "Formal proposal put to a meeting" , "Movement or proposal" , "Old coin of Germany" , "MP's proposal" , "Flow - proposal" .)
