First you shield your spacecraft with a gravity shielding device so it's not affected by earth gravity anymore. Then, even an emdrive's tiny propulsion output should be able to push your spacecraft all the way to space, powered with a clean cold fusion reactor. It's all imaginary though, but a man can dream...

Hmm, I'm not so sure. Once the gravity shield is invented, any reasonably strong human should be able to just throw the satellite into orbit. Why spend money installing an emdrive?
