Actually it is closer to 10.2299999954326 MHz... but only measured as
such when the bird is on ground.
This adjustment is done just before launch to compensate for the fact
that the gravitational pull is slightly less on the birds fligthpath.
Relativistics makes the clock go faster up there, so tune it sour before
letting it go will but it right when in place. If you where to measure
it at its place in the bird, it is 10,23 MHz.
Cheers,
Magnus
