Of course, how stupid of me, just the IOR satelite!
So intersect that with a fuel/flt time arc from the last "known" point and, assuming the various pings suggest a constant track, it is indeed likely to be toward the western end of the northern arc.
But someone knows the arcs of each of those pings ... and the northern arc in my opinion would remain at roughly the same distance from the satelite whilst the southern could well vary in distance considerably.
