Present and future space missions rely on systems of increasingly demanding performance for being successful. Drag-free technology is one of the technologies that is fundamental for LISA-Pathfinder, a European Space Agency mission whose launch is planned for the end of September 2015. A purely drag-free object is defined by the absence of all external forces other than gravity. This is not a natural condition and therefore a shield has to be used in order to eliminate the effect of undesired… 

Nanosatellites for quantum science and technology

Abstract Bringing quantum science and technology to the space frontier offers exciting prospects for both fundamental physics and applications such as long-range secure communication and space-borne



The Drag-free CubeSat

A drag-free spacecraft utilizes a Gravitational Reference Sensor (GRS) to shield an internal free-floating test mass (TM) from (a) external disturbances and (b) from disturbances caused by the

The Drag-Free Satellite

A scientific earth satellite that is guided in a drag-free orbit by a shielded, free-falling proof mass has been proposed by a number of investigators. This paper examines the feasibility and some of

Free-flight experiments in LISA Pathfinder

The LISA Pathfinder mission will demonstrate the technology of drag-free test masses for use as inertial references in future space-based gravitational wave detectors. To accomplish this, the

The paper outlines orbit and attitude control problems of a long-distance two-satellite drag-free formation for the Earth gravity monitoring and shows how disturbance dynamics and rejection are mandatory.

LISA Pathfinder drag-free control and system implications

The top-level requirement of the LISA Pathfinder mission is the verification of pure relative free fall between two test masses with an accuracy of about 3 × 10−14 m s−2 Hz−1/2 in a measurement

Principles, operations, and expected performance of the LISA Pathfinder charge management system

The test masses of LISA Pathfinder are free flying and therefore not grounded to the spacecraft by a wire. Because of galactic cosmic rays, solar energetic particles, and unknown microscopic surface

LISA Pathfinder test mass injection in geodesic motion: status of the on-ground testing

The LISA Technology Package (LTP) onboard the LISA Pathfinder mission aims to demonstrate, in orbit, several critical technology milestones for LISA, including the purest geodesic motion ever
