Real‐time precise orbit determination for FY‐3C and FY‐3D based on BDS and GPS onboard observation
(1) The real‐time precise orbit determination (POD) for low earth orbit (LEO) satellites based on spaceborne global positioning system (GPS) and BDS‐2 observations are executed. (2) Code multipath piece‐wise linear (PWL) error model of BDS‐2 satellites is constructed and applied to real‐time LEO POD.
