During gravity field and geoid model computation it became evident that the density of GSE gravity data distribution was higher than needed in geoid determination and caused computational burden in data processing.

We have set: [rho]' = [rho] + [t.sub.gravity] because we consider a stationary gravity field (in a general case, the gravity field is "dragged" along with the mass and [rho]' = [rho] + [t.sub.gravity] no longer holds).
Figures 8(a) and 9(a) show the gravity field variations along profiles A and B, respectively.
Regarding more engineering-oriented aspects, knowledge of the lunar gravity field directly affects spacecraft orbit determination (OD) and orbit propagation (OP) knowledge.
With this Resolution, it is recognizcd the importance of a globally-coordinatcd approach to Geodesy: the science focused on accurately measuring the shape, rotation and gravity field of planet Harth.

He said that as the spacecraft flies by Enceladus, its velocity is perturbed by an amount that depends on variations in the gravity field that we're trying to measure.
Using data from NASA's GRACE satellite, which measures changes in the Earth's gravity field, the scientists were able to calculate the way in which mass on the surface has been redistributed as ice has melted from ice sheets and glaciers.
