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.
