Sky plots are polar orthogonal plots illustrating the satellite's path as a function of elevation and azimuth which can be used in GNSS survey planning. Sky plots illustrates the geometry of the satellite constellation which is expressed mathematically as the geometric dilution of precision (GDOP) factor,

Presented, is the matlab code used to generate the figure on left using data from the reference station ALGO on DOY 62 2008 at 12:00 GPS Time. The azimuth and elevation angle is assumed known.
