Abstract: This article describes an algorithm for polynomial interpolation of GPS
satellite coordinates and its implementation in MATLAB. The algorithm is intended
for realtime 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 interploation precision.
Note: There are numerous MATLAB m-files included in this software package. Thus, the
the authors have bundled all files and sample data in a *.zip file (KTHorb.zip).
The Readme.txt file describes the directories created when the .zip file is unpacked.
The file Matlab_implementation.doc (or Matlab_implementation.txt) describes some
of the classes and methods included in the package for GPS satellite orbit interpolation.
