Abstract
The possibility of determining the attitude or orientation of the Helios spacecraft by means of polarization measurements of the spacecraft radio signal is described. One principal error source is the Faraday rotation of the S-band radio signal by Earth’s ionosphere. If this effect can be removed by independent measurements of the ionosphere, then the orientation of the spacecraft in two dimensions perpendicular to the spacecraft line-of-sight can be determined to better than 0.5 deg.
