There's a problem applying SR in this situation because neither the ground or orbiting clock is an inertial frame.AG
An orbiting clock is in an inertial frame. An inertial frame is just one in which no forces are acting (and gravity is not a force) so that it moves with constant momentum along a geodesic. Although it's convenient for engineering calculations, from a fundamental veiwpoint there is no separate special relativity and general relativity and no separate clock corrections. General relativity is just special relativity in curved spacetime. So clocks measure the 4-space interval along their path - whether that path is geodesic (i.e. inertial) or accelerated.
