title = "Efficient gravity field computation for trajectory propagation near small bodies",

abstract = "We present an approximation scheme for gravitational force near arbitrarily shaped small bodies. The approximation uses polynomial interpolation with an adaptive spatial data structure. This data structure allows us to drive errors in the model to within user defined thresholds. The result is a method that is expected to reduce the run time of trajectory integrations around small bodies without compromising accuracy. Our method is likely to provide a substantial improvement in the speed of Monte Carlo analysis of spacecraft motion in proximity to small bodies.",
