SKYPLOT for a given receiver position
Y=skyplot(X,PRN,C,O) draws the skyplot for the receiver position. The
required inputdata for the calculation of the skyplot X is N-by-3*M matrix,
where N are the timesteps and M is the number of the Satellites. The 1st
colomn is the elevation, the second colomn the azimuth and the 3rd colomn
is the geometric distance between sv and rx [° ° m].
The output Y is the same matrix als X, the only difference is that the
satellites below the cutoffangle are marked (number 9999 is written instead
the Elevation, Azimuth and distance.
The numbers of the satellites are listet in the voctor PRN (M-by-1), C is
the cutoffangle for the satellite elevation (default = 5°). The skyplot
displays only satellites who are visible for more then 10 times.
