Satellite TT&C confrontation will be a direct threat to the mastery of space and mastery of information in the war. Thus it has been focused by major military powers all over the world. Based on satellite TT&C confrontation, the principle of spacebased TT&C confrontation is proposed, the advantage and characteristic of spacebased TT&C confrontation are analyzed. The problem of spacebased TT&C confrontation in terms of jamming strategy, confrontation JSP and distance between two satellites are discussed, and the feasibility of satellite TT&C confrontation system in engineering practice is preliminary demonstrated. Finally，the composition and process of spacebased TT&C confrontation is proposed. These research achievements provide a elementary framework for the construction of TT&C confrontation system in the future.
