[amsat-bb] Satellite QRB records

[pedro at dutrasousa.name]

Hi,

I'm using formulas to determine the distance to the horizon from the  
satellite, then the distance across the (curved) surface between two  
opposite locations.
Again, it's meant for sea level. AO-7 solves with 7,858.478 Km which  
is below the record of 7,947.381 Km. This is because the higher from  
the sea level you are, the farther you are in the sat horizon.
I'll send you that list later today.
