Laser ranging interferometer for GRACE follow-on [PDF]

International Conference on Space Optics — ICSO 2012, 2017
The Gravity Recovery and Climate Experiment (GRACE) has produced a wealth of data on Earth gravity, hydrology, glaciology and climate research. To continue that data after the imminent end of the GRACE mission, a follow-on mission is planned to be launched in 2017, as a joint USGerman project with a smaller Australian contribution.

Arm locking with the GRACE follow-on laser ranging interferometer [PDF]

Physical Review D, 2016
Arm-locking is a technique for stabilizing the frequency of a laser in an inter-spacecraft interferometer by using the spacecraft separation as the frequency reference. A candidate technique for future space-based gravitational wave detectors such as the Laser Interferometer Space Antenna (LISA), arm-locking has been extensive studied in this context ...

Time-variable gravity field determination from GRACE Follow-On data usingthe Celestial Mechanics Approach extended by empirical noise modelling [PDF]

, 2022
We study gravity field determination from GRACE Follow-On satellite-to-satellite tracking using the inter-satellite K-band link and kinematic positions of the satellites as observations and pseudo- observations respectively.

Bridging the gap between GRACE and GRACE-Follow On by the combination of HLSST and SLR [PDF]

Journal of Physics: Conference Series, 2022
<p>GRACE has been undoubtedly one of the most important sources to observe mass transport at global and regional scales. Within the COST-G project, GRACE and GRACE-Follow On gravity field solutions from various processing centers are being combined to further increase the spatial and temporal resolution.

Using Swarm to Detect Total Water Storage Changes in 26 Global Basins (Taking the Amazon Basin, Volga Basin and Zambezi Basin as Examples)

Remote Sensing, 2021
The Gravity Recovery and Climate Experiment (GRACE) satellite provides time-varying gravity field models that can detect total water storage change (TWSC) from April 2002 to June 2017, and its second-generation satellite, GRACE Follow-On (GRACE-FO ...

Estimation of the Center of Mass of GRACE-Type Gravity Satellites

Remote Sensing, 2022
One of the key constraints for the accelerometer of GRACE-type gravity satellites to accurately measure the non-gravitational accelerations acting on the satellite is that the center of mass of the satellite and the proof mass of the accelerometer should
