Standardization of GPS Satellite Orbits is an important step in GPS data processing.In order to analyze the influence of the location of interpolation points,bands and extrapolation,we calculate 30-minute intervals data to 15-minute intervals data using barycentric Lagrange interpolation.The result shows that the precision for standardization of GPS satellite orbits of barycentric Lagrange interpolation is available when it is 10 bands.It has higher operation efficiency and stability process.
