Project Description

SmallSat Constellation

Improvements in the spatiotemporal resolution of time variable gravity (TVG) modeling are of primary importance for many science applications.   Our goal is to demonstrate that small satellite constellations coupled with precise laser ranging can provide a low-cost path for improving measurements of the Earth's TVG field.

Our goal is to demonstrate that small satellite constellations coupled with precise laser ranging can provide an improvement in the recovery of the large-scale components of the earth’s time variable gravity field as a scalable, low-cost and complimentary addition to future dedicated gravity missions.
