We present GravProcess, a set of MATLAB routines to process gravity data from complex campaign surveys and calculate the associated gravity field. Data reduction, analysis, and representation are done using the MATLAB Graphical User Interface Tool, which can be installed on most systems and platforms. Data processing is divided into several steps: (1) Integration of gravity data, station locati...

The Gravity Recovery and Climate Experiment (GRACE) its successor, the GRACE Follow-On (GRACE-FO) gravity satellite missions, have been providing monthly field solutions for almost 20 years, enabling a unique opportunity to monitor large-scale mass variation processes. anomaly time series Aral Sea region has obtained period of April 2002 January 2022. method determining from GRACE-FO improved b...

the problem of downward continuation of the gravity field from the earth’s surface to the reference ellipsoid arises from the fact that the solution to the boundary value problem for geoid determination without applying stokes formula is sought in terms of the disturbing potential on the ellipsoid but the gravity observations are only available on the earth’s surface. downward continuation is a...

In 1999, Georgia Tech conducted two field experiments to determine the performance of its mission specification system. The experiments were developed for the DARPA Tactical Mobile Robotics (TMR) Program and were conducted at Fort Sam Houston, Texas. The goal of the TMR Program is to develop robotic tools that can perform useful tasks on future military missions involving complex obstacle negot...

Low gravity astronaut extravehicular activity (EVA) missions using a maneuvering Jetpack and robotic servicing and assembly missions could benefit from spacecraft systems capable of maintaining pointing stability during critical operations. The addition of single-gimbal control moment gyroscopes (CMGs) to the attitude control system of these spacecraft could substantially improve the stability ...

New satellite missions are returning high precision, time-varying, satellite measurements of the Earth’s gravity field. The GRACE mission is now in its calibration/validation phase and first results of the gravity field solutions are imminent. We consider here the possibility of external validation using data from the superconducting gravimeters in the European sub-array of the Global Geodynami...
