I don't have a clue what you did, you have never posted that.
You have to add the change in PEnergy and KE of the satellite.
PE= INT Forcegravity*dh from Re to Rg
KEchange=final KE - Intial KE
now on the initial KE, remember that the launching point has a velocity as the Earth rotates.
I will be happy to critique your thinking on this.
