| Abstract: | To satisfy the construction of China Real-Time Precise Positioning Service System,a method of orbit determination of navigation satellite based on priori orbit dynamic information was proposed,in which the foregone dynamic orbit information and regional stations' measurement information are used together.The key techonique is how to assign weight to two above informations.Mathematic model of this method was introduced and transformation formulae of normal equations with initial orbit parameters at different... |
