ECAPS - Eddy Current Approach and Proximity Satellites

Completed Technology Project

Project Introduction

ECAPS - Eddy Current Approach and Proximity Satellites
Multiple, energized coils in a small satellite will generate eddy currents in the skin of the International Space Station (ISS). This will create repulsive forces between the satellite and the ISS. Coil configurations control tip/tilt of the satellite, while lateral forces can be generated using linear induction motor concepts where the coils are energized at shifted phases to make it appear that there is a traveling magnetic field. Creating attractive forces, to balance the repulsive forces for controlled flight of the satellite, will be accomplished through a frequency dependent phase relationship between the coil current and the eddy current. This is complimentary to previous work done by another researcher. The project will begin with developing the models and performing experimental verifications of the interaction of a single coil with a conductive sheet, then expand to coupled coils in order to demonstrate lateral forces. Feasibility and capability of the ECAPS will be determined, and peer reviewed journal paper and final report will be published. More »
