Ben Cartwright

Finishing a Master's degree in Electronic Engineering and Computer Science in the UK, Ben will shortly be starting as a graduate Electronics Design Engineer at STFC RAL Space in Oxford.  His primary interests are in cubesats and high power rocketry, and developing the electronic systems within.

Ben is also a member of staff on the UKSEDS operations and outreach teams, as well as a founding member of The Mars Generation.

STRUCTURAL DESIGN

AstonSAT is an engineering model of a cubesat built for Ben's Master's project.  Large parts of the project revolved around a working Attitude Determination System, so a prototype chassis was built, emulating the Planetary Systems Corp cubesat standard, to allow the testing of sets of directional sensors and the integration of the electronics stack.

ELECTRONICS DESIGN

Ben led development of a series of electronic systems as part of the AstonSAT cubesat design project.  Although his primary role was in the development of the Attitude Determination System, using two sets of coarse sun sensors and Kalman derived sensor fusion, he also worked on the top-level system design, electronics preproduction, and integration with the mechanical components.

CONSTELLAR

HIGH POWERED ROCKET

Constellar is a work in progress rocket being designed and built to get L1 and L2 High Power Rocketry certifications, with the aim of being able to support development of an eventual flagship rocketry project with The Flame Trench.

Research at RAL Space

In the third year of his degree Ben worked at STFC RAL Space as an electronic engineer, conducting research and development into Digital Correlated Double Sampling - a method of reducing read noise from scientific CCDs.  He worked with prototypes and flight electronics from the JPAS telescope in Spain and NASA's Solar Dynamics Observatory respectively.  He also worked on a proposal for a cubesat flying Phase4's Cubesat Ambipolar Thruster.

Ahi-I

EXPERIMENTAL ROCKET ENGINE

Ahi-I began as an attempt to design a gasoline/GOX rocket engine with approx. 50N thrust.  Although still in the design phase, prototype 3D prints have been used to verify stages of the combustion chamber and coolant saddle design.  Ben is currently working on injector design when he has spare time, however he's waiting on a funding source before making this project a focus.
