Byron seeks to assess the contribution that a constellation of nanosatellites could make towards the determination of Earth's time variable gravity. This entails quantifying the scientific return of such a nanosatellite constellation, as well as the specific mission design and hardware requirements. This will be accomplished by numerical simulations, along with the experimental testing of a nanosatellite platform utilizing state-of-the-art GNSS receivers and the latest in MEMS technology. Byron is advised by Dr. Brian Gunter.
