The actual version requires the following MATLAB toolboxes:

- Mapping toolbox (for elevation())

- Image Processing Toolbox (for imshow())

A providing of toolbox independent functions would be greatly acknowledged.



You may tweak the sourcecode to adjust the following information:

- Receiver Position

- Receiver Time offset to GMT

- Path of ephemerides file

- Path for satellite track recordings



Ephemerides are taken from

http://www.celestrak.com/NORAD/elements/galileo.txt

and should be updated from time to time



The satellite position calculation (calc_satposition_ecef.m) is based on a program from the Institute of Systems Optimization (ITE) at the University of Karlsruhe, Germany (http://www.ite.uni-karlsruhe.de/).
