Abstract
Due to the very small displacements that the LISA Pathfinder payload will measure, (in the order of 10-8 meters) the LPF mission has been designed to minimise the sources of physical disturbance to the payload sensor. However small scale disturbances (e.g. solar flux noise) can not be completely removed by mission design and the effects of these disturbances must be understood. A Power Spectral Density (PSD) thermal analysis has been employed to demonstrate the thermal stability of the spacecraft remains within specified limits between 0.1 and 0.001Hz).
This paper discusses the thermal considerations and trade-offs which are important in the design of this mission, and examines the effect of thermal noise sources on the payload.
