Abstract
The Photospheric and Helioseismic imager (PHI) on board of the ESA mission Solar Orbiter, to be launched in 2017, will provide measurements with high polarimetric accuracy of the photospheric solar magnetic field at high solar latitudes. The needed pointing precision requires an image stabilisation (ISS) to compensate for spacecraft jitter. The image stabilisation system works as a correlation tracker with a high-speed camera and a fast steerable mirror. The optomechanical and electronic design of the system will be presented.
