The invention discloses a satellite navigation method for wide-area detection on a stellar surface. The satellite navigation method comprises the following steps of: (1), realizing a spatial circular queue through the control of an orbit parameter by adopting a group of navigation satellites, wherein the group of navigation satellites at least comprises a primary navigation satellite and two auxiliary navigation satellites; (2), acquiring the spatial positions of all the navigation satellites; (3), synchronizing time among all the navigation satellites through an inter-satellite link phase-locked communication; (4), issuing time signal information and ephemeris data information to a terminal user by all the navigation satellites; and (5) receiving the time signal information and the ephemeris data information of all the navigation satellites by the terminal user, and resolving the position of the terminal user by utilizing time difference measurement and curve intersection to realize the navigation positionin
