This report presents the design of a 12U Gravimetry CubeSat. Gravimetry Satellites carry sensors that measure gravitational readings over ice caps to map geophysical characteristics and help study climate change. CubeSats provide a cost-effective way to carry on the work of previous gravimetry missions. This 10-year mission uses two satellites at inclinations of 91 and 103 degrees to ensure global coverage. Orbital design was performed using Systems Tool Kit (STK®). A Gradiometer was developed with six high-precision accelerometers. Mechanical design was conducted in SolidWorks and Ansys. An Attitude Determination and Control System alongside an on-board computer and communications system was designed. Power generation, electric propulsion, thermal, and radiation effects were analyzed in STK®. The Polar-Orbiting Gravimetry CubeSat (POGSat) was designed to provide complete global mapping of the Earth’s gravity field every three weeks, with a mission duration of 10 years, a marked improvement from previous gravimetry missions such as GOCE.
