AbstractThe Solar Probe Plus (SPP) mission is the culmination of decades of studies on spacecraft designed to explore the inner region of the heliosphere. The mission is being implemented by the Johns Hopkins University Applied Physics Laboratory for a 2018 launch. Building on the flight experiences of the Helios (NASA/FRG) and MESSENGER (NASA/JHUAPL) spacecraft and several remote studies, SPP will be the closest operating spacecraft to the Sun, even surpassing the 2017 planned launch of the Solar Orbiter (ESA/NASA) spacecraft. At a 9.86 solar radii perihelion, this places SPP in an environment where small deviations from planned attitude and appendage positioning can have catastrophic consequences. To demonstrate engineering feasibility and survivability, the Guidance & Control simulation must capture the significant spacecraft design elements and environmental factors affecting true spacecraft and appendage motion. This truth dynamics model is then coupled with simulated sensors to the simulated flight G&C system to validate the design. This paper presents the influences driving the dynamics of the spacecraft in the current modeling of the SPP G&C truth dynamics simulation.
