But in practice the satellites won't be sitting and waiting at the edge 
of this 940km radius. They are moving in and out the radius and the 
question is if satellite density is high enough so that once the serving 
satellite loses its gateway link there's another satellite in the 940km 
radius which also covers Tonga. And then this new satellite cannot be 
within certain elevation angles (~60-80° at 0° azimuth) where the 
geostationary arc crosses Fijian skies and the gateway antennas have to 
seize emission. My gut feeling is that availability in Tonga would be 
<90% simply because it's too far out at the edge of a Fijian gateway's 
range where there will be frequent service interruptions.
