This is a wrong statement.

No, it is not.


Kindly ascertain the facts and correct it.

_YOU_ need to do that.


In PARCS the GR correction is expected to be of the order of 0.27
micro sec/day

Please actually read what is written, and apply basic reading skills: PARCS is not the GPS. <shrug>


PARCS is designed to fly in the ISS, at its altitude, not at the GPS satellite altitude. This accounts for the difference (though I have not checked your value for PARCS). Indeed, at low earth orbit even the _sign_ of the difference changes, and a clock orbiting ~100 miles up (e.g. in the space shuttle) will _lose_ time relative to ground clocks.

This is all just an elementary application of GR to the conditions of the various orbiting clocks. There is nothing new or surprising here, and this is all well known (by people who understand such things, anyway).
