Abstract:

Gravity fields have become increasingly large. Subsets of the gravitational field are commonly used to limit computational time spent finding accelerations. But is a 70×70 subset out of a 360×360 field the same as a 70×70 subset from a 2190×2159 field? We discuss working approaches to using full gravity fields and document the factors involved in doing analyses of the results. We also update a digital gravity model that can be used with the complete gravity field, or a significantly large subset, at comparable computational times to traditional subsets.
