POLYNOMIAL INTERPOLATION OF GNSS SATELLITE COORDINATES
BASED ON POSITION AND VELOCITY INFORMATION
Chinese Academy of Surveying and Mapping，Beijing 100830
Abstract Polynomial fitting and interpolating of precise or broadcast ephemeris will be affected by Runge’s phenomenon.Satelites’ position and velocity information were used to remove the influence of Runge’s phenomenon.The result shows that the outside precision of 8hour fit interval can reach millimeter level.
Key words ：
GNSS
precise ephemeris
broadcast ephemeris
polynomial interpolation
Runge’s phenomenon
