International challenges of GRACE Follow-On

2017 IEEE Aerospace Conference, 2017
The Gravity Recovery and Climate Experiment-Follow-On (GRACE-FO) Mission is a NASA directed mission to continue the goals of the original GRACE mission and provide continuity for the GRACE data set. The GRACE-FO mission is the result of an international cooperation to develop a concept and approach that minimizes cost and risk and maximizes the ...

Bridging GRACE and GRACE Follow-On TWS gap using forward-backward autoregressive model

2022
<p>Nowadays, huge number of regions spread around the World are struggling with the problem of water availability. Hence, the quality and quantity of continental water resources must be regularly controlled. Currently, land water components are monitored, among others by measuring their weight, type and density or analyzing the level of ...

V04 Level-1 data processing status for GRACE and GRACE Follow-On

2020
<p>On May 22, 2020, the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO), will celebrate two years of successful in-orbit operation. The primary goal of this satellite mission is to provide information about time variations of the Earth’s gravity field. This is possible due to precise orbit determination

Overview of the GRACE Follow-on Mission

Light, Energy and the Environment, 2014
The GRACE Follow-on mission will map Earth’s gravity to monitor melting of polar ice and changes in continental ground water. We present GRACE Follow-on’s new laser ranging instrument developed by US, German and Australian scientists.

Merging GRACE Follow-On gravity fields with various approaches

2022
<p>For the 2002–2017 period, an essential information about global monthly gravity variations was provided by the Gravity Recovery and Climate Experiment (GRACE) mission. Gravimetric mission have given a new opportunities to analyze fluctuations in the Earth's system, so GRACE observations is widely used in various fields of

Reconciling ocean mass changes from 20 years of GRACE and GRACE Follow On observations

The total mass change of the Earth's land surface precisely offsets the combined changes in the atmosphere and oceans, resulting in a net-zero change for the entire system (land+ocean+atmosphere).Closing the ocean mass budget is crucial for understanding current and future sea-level changes.

Laser Ranging Interferometer on GRACE Follow-On: Current Status

2020
<p>The GRACE Follow-On satellites were launched on 22<sup>nd</sup> May 2018 to continue the measurement of Earth’s gravity field from the GRACE satellites (2002-2017). A few weeks later, an inter-satellite laser link was established with the novel Laser Ranging Interferometer (LRI), which
