During the LISA Pathfinder mission, several unexpected changes in test mass acceleration, or “glitches”, were observed. As LISA relies on extreme stability of the test masses for accurate data collection, we wish to know the extent to which similar dynamical glitches on the LISA spacecraft will affect our measurements, and whether they can be mitigated. To that end, we present simulations of the LISA instrument’s TDI response to these glitches, and propose a technique for detecting, and potentially removing glitches from data. The latest stage of the LISA Data Challenge, Spritz, contains the same type of glitches discussed here, and can serve as a test of the removal techniques.
