    I have been scratching my head, trying to fiqure out why the following site
    
    http://tycho.usno.navy.mil/gpscurr.html
    
    Says "The current GPS constellation consists of 30 Block II/IIA/IIR/IIR-M satellites". I got 29,
    when I was looking at data located at
     
    ftp://tycho.usno.navy.mil/pub/gps/gpsb2.txt
    
    There's a black star beside IIA-17 ( PRN 29 ) which they say 
    
    *  Satellite is no longer in service "
    
    Wrong!
    
    I see it's operational, ie transmitting a signal:) I am getting a signal from it on my gps
    receiver. 
    
    So that explains the missing one, I didn't included in a list I keep. I thought it was turned off,
    based on that " *  Satellite is no longer in service " line.
    
    I was fooled by them, I am on to them now.
