Kinematic Orbit Determination of Low-Earth Orbiters Based on GPS Precise Point Positioning Technique

  • In order to advance orbiting results obtained using the present kinematic orbit determination method,the principle and mathematic model of kinematic orbit determination based on GPS PPP(precise point positioning) technique considering dynamic information on a low-earth-orbiter(LEO) were analyzed.By using smoothed orbiting result as the priori orbit of an LEO,an improved majority voting method was proposed and successfully used in kinematic orbit determination.With this proposed method,the quality of data pre-processing based on undifferenced observations from an onboard GPS receiver can be improved and big phase breaks causing many gaps in the orbit of an LEO can be avoided efficiently,as a result,orbiting accuracy can be enhanced.
