Description: 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.- SKYPLOT for a given receiver position

Description: ELEVAT calculation for elevation, zenit angle and spatial distance
e_az_s=elevat(D,RHO) computes the elevation, the zenit angle and the
spatial distance between a satellite(j) and a receiver(i). The receiver
position (D) is a 3-by-3 matrix [n e u] and the distance between the
sv and rx (RHO=X(j)-X(i)) is a N-by-3 vector with N satellite postitions
calculated from spatial coordinates in m.
The output e_az_s is a N-by-3 vector and contains the elevation angle [°],
the zenit angle [°] and the spatial distance [m] from the rx to the sv.- ELEVAT calculation for elevation, zenit angle and spatial distance

Description: 这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible).
The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot).
The script is not fully optimize

Description: 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/).
