Description: ALM2POS computation for satellite position from almanac data file
[pos,R]=alm2pos(almanac,PRN,time) calculates the satellite position in the
Terrestial and in the Celestial reference frame for a desiderate satellite
vehicle (PRN) with almanac data (ALMANAC). The given time (TIME) can be a
scalar or also a vector. Colomn 1-3 of position (pos) are Terrestial
Coordinates (ECEF) colomn 4-6 of position are Celestial Coordinates (ECSF)
in m. Another output is the position vector of the satellite (R) in m.- ALM2POS computation for satellite position from almanac data file

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: 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/). Platform: |
