Payload accommodation on Solar Orbiter S/C. The RPW sub-units are indicated in red. The electric Antenna system (ANT) consists of a set of three identical antennas deployed from +Z axis (Antenna PZ) and from the opposite corners of the S/C +Y and -Y walls (Antennas PY and MY). The SCM consists of a set of three magnetic antennas mounted orthogonally. Their orientations, in the S/C reference frame, are given by the three vectors in the upper left part of the figure. Finally the Main Electronic Box (MEB) is located inside the S/C body.
