Abstract: Actually,the satellite precision orbit determination is a iterated process to improve the initial orbit by solving the dynamic differential equation group.So that,the precision and calculating rate of the orbit is depends on the solve algorithm of the differential equation and the precision and veracity of the initial orbit.For the ranges or two-way ranges data observed by some stations synchronously,a geometry method was proposed to determine the satellite initial orbit.The method combined the radio wave refraction error correction method with itself can improved the precision greatly.
