Solar Orbiter/PHI Electrical Functional Model ready for delivery

July 15, 2015

The Electrical Functional Model (EFM) of the Polarimetric and Helioseismic Imager (PHI) for the upcoming joint ESA/NASA Solar Orbiter space mission is ready for delivery to Airbus DS and for integration into the electrical test bench of the spacecraft.

The PHI EFM provides full electrical functionality including detectors, mechanism drives and onboard software. During the science phase of the mission the EFM will serve ESA and the instrument team as a ground reference model for commanding and resource testing.

The PHI instrument is designed to first ever perform substantial in-flight scientific data calibration and analysis which requires sophisticated onboard data processing hard- and software.
