Several numerical codes aiming at calculating spacecraft plasma interactions have been developed over the world. They generally calculate plasma dynamics, current emission/collection on spacecraft and spacecraft charging. Among these codes, SPIS and MUSCAT have been developed by ONERA/DESP and KIT respectively. SPIS, the Spacecraft Plasma Interaction Software, has been developed with ESA support and ameliorated via several CNES R&T contracts so as to provide the community with an open-source software dedicated to the environment effect on satellites. The numerical core and the user interface have been developed by ONERA and ARTENUM respectively. The effect of in-orbit plasma on spacecraft has been modelled in a wide range of configurations: electric propulsion, GEO charging, barrier of potential. The ONERA plasma chamber JONAS has also been simulated and the results compared to experiments. SPIS also takes account of all phenomena involved in ESD triggering. It has permitted to confirm a physical model of ESD triggering by numerical simulations. MUSCAT, the Multi-Utility Spacecraft Charging Analysis Tool, has been in development since 2004 and the final version was released in March 2007. The comparison to experiments has also been achieved in a wide range of configurations. By now, the models have been tested independently. The objective of this work is to provide a first attempt of SPIS and MUSCAT cross validation. It consists in comparing them in a typical LEO-like environment. First simulations were performed in previous work using MUSCAT to solve plasma dynamics around a plate immersed in drifting plasma. The work presented in this paper consisted in using SPIS in the same configuration. The results show a good qualitative and quantitative agreement with similar plasma sheath, particle dynamics, wake and particle collection. In near future, better quantitative agreement could be achieved by using closer models. The next step would then be to simulate the spacecraft charging at GEO.
