Ruwisch, Fabian; Jain, Ankit; Schön, Steffen
(Basel : MDPI AG, 2020)
We present analyses of Global Navigation Satellite System (GNSS) carrier phase observations in multiple kinematic scenarios for different receiver types. Multi-GNSS observations are recorded on high sensitivity and ...

(College Park, MD : American Physical Society, 2019)
Deep-frequency-modulation interferometry combines optical minimalism with multifringe readout. However, precision is key for applications such as optical gradiometers for satellite geodesy or as dimensional sensors for ...

(Basel : MDPI AG, 2018)
We present ground deformations in response to water level variations at the Toktogul Reservoir, located in Kyrgyzstan, Central Asia. Ground deformations were measured by Envisat Advanced Synthetic Aperture Radar (ASAR) and ...

Mirzaee, S.; Motagh, M.; Akbari, B.
(Göttingen : Copernicus GmbH, 2017)
Shabkola is a village located in Mazandaran province of northern Iran that suffers from the mass movement happening in the upstream. Deforestation and changes to land use are the main reasons for the soil instability in ...

Koch, Alexander; Sanjuan, Josep; Gohlke, Martin; Mahrdt, Christoph; Brause, Nils Christopher; Braxmaier, Claus; Heinzel, Gerhard
(Washington, DC : Optical Society of America, 2018)
The laser ranging interferometer (LRI) on board of the GRACE follow-on spacecraft, launched in May 2018, is the first laser interferometer to perform an inter-satellite range measurement. It is designed for ranging noise ...

Schütze, Daniel
(Bristol : Institute of Physics Publishing, 2016)
The GRACE mission that was launched in 2002 has impressively proven the feasibility of low-orbit satellite-to-satellite tracking for Earth gravity observations. Especially mass transport related to Earth's hydrological ...

Schwarze, Thomas S.; Fernández Barranco, G.; Penkert, D.; Gerberding, Oliver; Heinzel, Gerhard; Danzmann, Karsten
(Bristol : Institute of Physics Publishing, 2016)
The planned spaceborne gravitational wave detector LISA will allow the detection of gravitational waves at frequencies between 0.1 mHz and 1 Hz. A breadboard model for the metrology system aka the phasemeter was developed ...

Zhong, Luping; Sośnica, Krzysztof; Weigelt, Matthias; Liu, Bingshi; Zou, Xiancai
(Basel : MDPI AG, 2021)
The Earth’s time-variable gravity field is of great significance to study mass change within the Earth’s system. Since 2002, the NASA-DLR Gravity Recovery and Climate Experiment (GRACE) and its successor GRACE follow-on ...

Sefercik, Umut Gunes; Sörgel, Uwe
(Göttingen : Copernicus GmbH, 2010)
SAR Interferometry (InSAR) is a technique to derive Digital Elevation Model (DEM) from at least two complex SAR images. The data are either taken simultaneously (single-pass mode) or sequentially (repeat-pass mode) by ...

Chen, Qiang; Poropat, Lea; Zhang, Liangjing; Dobslaw, Henryk; Weigelt, Matthias; van Dam, Tonie
(Basel : MDPI AG, 2018)
Over the 15 years of the Gravity Recovery and Climate Experiment (GRACE) mission, various data processing approaches were developed to derive time-series of global gravity fields based on sensor observations acquired from ...

Vishwakarma, Bramha Dutt; Devaraju, Balaji; Sneeuw, Nico
(Basel : MDPI AG, 2018)
The mass change information from the Gravity Recovery And Climate Experiment (GRACE) satellite mission is available in terms of noisy spherical harmonic coefficients truncated at a maximum degree (band-limited). Therefore, ...
