Abstract
The post-Newtonian terms included in the Frequency Difference of Arrival equation derived here by means of Synge’s world-function are considered to estimate their contribution in the precise Geolocation of passive radio transmitters at rest on the earth surface. Four of these terms are kinematical and the other two are gravitational. The kinematical terms account for the velocities of the radio transmitter and the receivers with respect to the Earth Centered Inertial reference frame, as well as for the relative velocities of the transmitter with respect to the receivers. The other two account for the gravitational attraction of an spherical earth on the receivers. The gravitational time delay has been taken into account to derive these terms.
