  In a light-pulse atom interferometer, we use a tip-tilt mirror to remove the
influence of the Coriolis force from Earth's rotation and to characterize
configuration space wave packets. For interferometers with large momentum
transfer and large pulse separation time, we improve the contrast by up to 350%
and suppress systematic effects. We also reach what is to our knowledge the
largest spacetime area enclosed in any atom interferometer to date. We discuss
implications for future high performance instruments.
