Spacecraft communication systems operating at X-band are strongly affected when the propagation path passes close to the sun (which can be characterised by the Sun-Earth-Probe, SEP, angle). In this paper, a channel model that can generate a time-series of signal amplitude and phase, and hence the signal in-phase and quadrature values, is presented. For X-band, the channel model reproduces the observations well for SEP>0.8°. While the model has not been experimentally validated at SEP angles below 0.8°, the behaviour is consistent with measurements reported in the literature and is therefore likely to be suitable for use, with caution, in that region too.
The work described here forms part of the HELIOS (Highly rEliable LInks during sOlar conjunctionS) project which has been funded by the General Study Programme (GSP) of the European Space Agency under Invitation To Tender Reference: AO/1-8050/14/F/MOS.
