Study to Develop Use of Gravity Gradiometers in Gravity Mapping.
Abstract
Gravity mapping requires a form for storing the data about the gravity field as well as an ability to make measurements and interpret them. The studies at Stanford University have included comparisons of gravity field models as well as some of the concerns associated with gathering data. Our earliest work included modeling of gravity gradiometer instruments in an attempt to correct for instrumental errors and reduce the residual measurement errors before doing gravity fitting. More recent work has been concerned with the errors introduced by mass attraction gradient of the vehicle carrying a gradiometer while data gathering and the proper patterns to use to maximize the separation of uncertainties in the gravity field from measurement noise. Keywords: Inertial guidance; Navigation; Mascon approximations; Efficient Gravity Gradient Data Gathering.
