Plans are presented for an experiment to measure the gravitational red shift of the Earth by comparing a ground-based and satellite-borne hydrogen maser clock. The limiting accuracy is estimated to yield a determination of the red shift to 1 part in 105, corresponding to a clock stability of 3 parts in 1015.
