In the field of space remote sensing technology, this paper researches on the technologies of high precision and long life tracking mechanism. The especial requirements in space for tracking mechanism are presented firstly, and the technologies are studied. Then a tracking mechanism bearing by two flexural pivots and driven by a voice coil motor is designed. Flexural pivot is ideally suited for limited angular rotation. Voice coil motor has a simple structure, without any structure for reversing, and is easy to be controlled. The mechanism’s tracking accuracy can reach to 30″, and the life of this tracking mechanism can reach to 3.6E+6 which are all proved by some test in the end.
