Data processing and noise subtraction for the LISA technology package — •Frank Steier, Felipe Guzman, Antonio Garcia, Vinzenz Wand, Gerhard Heinzel, and Karsten Danzmann — Zentrom für Gravitationsphysik Hannover, Callinstr. 38, 30167 Hannover

The LISA technology package is a technology demonstration for the future Gravitational Wave detector LISA. On board LISA Pathfinder the length change between two free falling test masses is measured interferometrically with picometer accuracy in a frequency range between 1 mHz and 30 mHz.
We show how redundant interferometrical signals are combined, noise subtraction for the longitudinal measurement is done and control loops with downsampling and asynchronous data transfer are implemented.
