| Abstract: | This article describes an algorithm for polynomial interpolation of GPS satellite coordinates and its implementation in MATLAB.
The algorithm is intended for real-time processing software and computes the position and velocity of GPS satellites from
both broadcast and precise ephemerides. Tests with different orders of polynomials, and with different time spans used for
polynomial fitting, show suitable settings with respect to the required interpolation precision. |
