Satellite based precision measurements of Earth's gravity field have unlocked the dynamics of land masses, glaciers, aquifiers and oceans with application to Earth science, climate science and in the future, planetary science. One of the limitations of satellite observations of Earth is the long-term drift of the accelerometers that monitor and correct for drag on the satellite. To date classical accelerometers have been used to perform this task. Although these are advanced, cutting edge sensors, all suffer from long term drift and insufficeint sensitivity for some tasks. The aim of this project is to design, numerically model, construct and test a new concept in quantum limited measurements of acceleration suitable for space deployment.
