I'm using code from a Fortran program called solid.f that I converted to C using F2C and modified to use more accurate sun / moon positions. The solid.f program is based on an edited version of the dehanttideinelMJD.f source code provided by Professor V. Dehant. This code is an implementation of the solid earth tide computation found in section 7.1.2 of the IERS Conventions (2003) , IERS Technical Note No. 32.
The gravity offset calculation is based upon TVB's tides.c:
> This is all new information to me - and fascinating! Have you just
"calculated" the offsets (using known values from somewhere), or "measured"
it by very long term averaging of the GPS position information?
