Looks like you were right! The gravitational effects win out over the opposing effects due to the high speed of the satellite.

Actually I was using that example to show when I was wrong : ) I learned it the hard way when I was helping design the guidance system for the Tomahawk.

Wow! Very impressive. Thanks for your service on the program.

Of course the gravitational slowing down of the earthbound observer’s clock would depend on where he/she was on the Earth’s surface. Some locations have a higher level of gravity than others. It depends on the density of the rock below. Also, near the equator, there is an outward force (acting in the opposite direction from gravity) due to the spinning of the Earth (about 900 miles/hour at the equator).
