Drag-free satellites maintain geodetic trajectories while powering interferometers via shielded internal positioning systems
Evidence from space-borne gravitational wave detector research confirms that drag-free satellites use shielded internal test masses to maintain precise trajectories while supporting space-based interferometers.
The retrieved literature consistently supports the claim that drag-free satellites use shielded internal test masses (positioning systems) to maintain geodetic trajectories and support high-precision space interferometers (such as for gravitational wave detection). Papers [0], [4], [9], and [10] explicitly discuss these mechanisms and control systems.
