Previous analysis, made just after the Venus swing-by#2 by the ESA/ESOC flight dynamics department, proved that the orbit determination software during the swing-by added It is worthwhile to remark that the analysis of VSB2 data confirms that ISA like high-sensitivity accelerometers are key instruments for the spacecraft fine-dynamic and Precise Orbit reconstruction in the regime of small and very small accelerations, overcoming the need of modelling them that would be an extremely challenging and sometimes not feasible activity in such complex scenarios.
