A Measurement of the General Relativistic Time Delay With Data From Mariners 6 and 7The technique for obtaining range measurements is discussed. It involves measuring elapsed time between the transmission of an encoded signal from the ground station and its return from the spacecraft. The theoretical background for the Mariner Mars 1969 relativity test is presented, including computation of orbits and time transformation. Interplanetary and coronal plasma effects on range and Doppler observations at S-band are also considered. The general relativistic propagation delay was measured and a value of 0.997 for the relativity parameter Gamma star was obtained.
