KUL was tracking MH370 on secondary radar at the time of the handoff. Was the next ATC also able to track MH370 on secondary radar at the time of handoff before the Xpdr went off? Did either ATC track MH370 on primary radar? If not, why not. Would not a target with the <acronym title="Rochester (RCS...

You are correct, if the satellite were truly geostationary the north and south track would be symetrical in terms of Doppler.

RE: MH370 Malaysia Airlines B772 Missing Enroute KUL-PEK Part 58

If the fundamental measurement of the round trip time delay has an uncertainty of +/- 300 us (which seems to be a fact) then the ROUND TRIP distance has an uncertainty of about +/- 48.6 nm.

This corresponds very roughly to +/- 24 nm in position on the Earth.

If the pre-correction method is b, then the residual offset remaining is due to only the satellite motion which is exactly what you need to break the north south symmetry.
