I have wondered the same thing.
Their premise: the pings stayed the same distance from a geosynchronous satellite over the Indian ocean.
But I wonder: how accurate? Plus or minus how much?
As the +/- tolerance gets bigger, the two arcs from last radar contact (based on the satellite) get wider.
If they get wide enough, they would merge, and literally the entire Indian Ocean is your search area.
DME tolerance is +/- 3%. Are satellite pings the same......or worse?
