To eliminate non-gravitational forces such as light pressure and solar wind on the test masses, each spacecraft is constructed as a zero-drag satellite, and effectively floats around the masses, using capacitive sensing to determine their position relative to the spacecraft, and very precise thrusters to keep itself centered around them.[3] This technology was pioneered by the TRIAD satellite in 1972. A single satellite (“LISA Pathfinder”), to be launched in 2013,[5] will test drag-free operation as it will be implemented in LISA.
