Solar Orbiter is a future spacecraft dedicated to solar and heliosphericphysicsscheduledforlaunchinOctober2018. The Radio Plasma Waves (RPW) instrument will measure electric fields at high time resolution using three electric antennasmountedonboomsinaperpendicularplanetothe spacecraft-Sun axis. Effective antenna lengths and directions will be different from the physical ones due to their thermal bending and coupling with the spacecraft body. This paper discusses the variations of the RPW’s direction finding capability for interplanetary solar radio emissions as a function of the distance from the Sun.
