    It does account for elevation, in this case 202 meters above geoid for 
    the location. My main concern is the calculation. I update the satellite 
    and Sun positions every 1/4th of a second in the last 10 seconds. The 
    error therefore could possibly be as wide as 4 arc minutes. Acceptable 
    or not, difficult for me to judge.
