I should have said Edwin Taylor. You can read about GPS and GR here:

Apology to Prof. Taylor.

I took both of Edwin F. Taylor's classes on special and general
relativity when he taught at Harvard Extention School in the early
1990's. I recall doing the cited calculation then. Here is the
equation for the difference in stationary satellites (Eq. 4):

dt_satellite/dt_Earth = (1 - 2 M/r_{satellite})^(1/2)(1 - 2 M/r_{Earth})^(-1/2)

For the exponential metric, g_{00} = e^(-2 M/r). Do a [Brook not Edwin F]
Taylor series in M/R, keep the first term of that expansion, and the
ratio of g_{00}^(1/2) for different r's will be the _exact same_
algebraic expression. GPS tests of general relativity to first order
in M/r are consistent with the exponential metric.
