The Microscope mission by CNES is a test of the Equivalence Principle with a microspacecraft in low Earth orbit. The propulsion system for this satellite has unique requirements: very low thrust, accurate thrust throttling, stringent mass and power constraints. The system will be used to compensate for non-gravitational forces on the spacecraft, enabling it to fly along an inertial trajectory, in the so called “drag-free” mode. This paper presents the architecture of the micronewton FEEP system for MicroScope, illustrating the configuration constraints and the resulting design choices.

Abstract
The Microscope mission by CNES is a test of the Equivalence Principle with a microspacecraft in low Earth orbit. The propulsion system for this satellite has unique requirements: very low thrust, accurate thrust throttling, stringent mass and power constraints. The system will be used to compensate for non-gravitational forces on the spacecraft, enabling it to fly along an inertial trajectory, in the so called “drag-free” mode. This paper presents the architecture of the micronewton FEEP system for MicroScope, illustrating the configuration constraints and the resulting design choices.File in questo prodotto:
