Abstract: The spacecraft on the tourist orbit can travel around the GEO without control force. There are some disadvantages with the groundbased exploration network, so that the tourist orbit is supposed to improve the surveillance capability .In this paper, a initial orbit design is improved based on the previous design. Then by applying the control, two methods are proposed to observe the multiple targets on the GEO. Finally, simulation validations are given and their respective advantages are compared.
