 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.
